Question 621Question →

When analyzing the blueprints for the new library, the head architect noticed that the two consultants' proposal had its own set of structural flaws.

Which of the following is the best replacement for the underlined portion?

Show answer & explanation

Answer: NO CHANGE

Answer

The correct option is 'NO CHANGE' because it correctly uses the plural possessive 'consultants\'' to show that the proposal belongs to two consultants, and the possessive pronoun 'its' to modify 'own set of structural flaws'.
The sentence correctly uses the plural possessive 'consultants\'' to indicate that the proposal belongs to two individuals, and the possessive pronoun 'its' (without an apostrophe) to show that the structural flaws belong to the proposal.

Step-by-Step Solution

1
Determine if the noun 'consultants' should be singular or plural, and possessive or not.
The sentence specifies 'two consultants,' indicating a plural noun. Since they possess the proposal, we need the plural possessive form, which is written as 'consultants\'' with the apostrophe after the 's'.
Using 'consultant's' would incorrectly indicate that only one consultant is involved.
2
Determine if a contraction or possessive pronoun is needed before 'own set'.
We need to show that the flaws belong to the singular proposal, which requires the possessive pronoun 'its'.
The contraction 'it's' stands for 'it is' or 'it has,' which would result in 'had it is own set,' which is grammatically incorrect. There is no such word as 'its\''.
3
Compare these findings to the original underlined text.
The original underlined text matches the correct grammatical choices: 'consultants' proposal had its'.
Since the original phrasing is correct, 'NO CHANGE' is the correct selection.

Question 622Question →

The two guitarist's instruments were carefully tuned before the concert began.

Which of the following is the correct spelling and punctuation of the underlined word in the sentence above?

Show answer & explanation

Answer: guitarists'

Answer

The correct option is the plural possessive form 'guitarists''.
The correct answer is the plural possessive form 'guitarists''. Since the sentence describes two individuals who own the instruments, a plural possessive is required. For regular plural nouns ending in 's', possession is shown by adding an apostrophe after the 's'.

Step-by-Step Solution

1
Determine if the noun should be singular or plural based on context clues.
The sentence contains the number 'two' right before the noun, indicating that there is more than one guitarist. Thus, a plural noun is needed.
The modifier 'two' establishes that the noun represents multiple entities.
2
Determine if the noun needs to be possessive.
The instruments belong to the guitarists, meaning a possessive form is necessary.
Possession must be marked to connect the owners (guitarists) to the owned objects (instruments).
3
Apply the punctuation rule for forming plural possessives for nouns ending in 's'.
The plural of 'guitarist' is 'guitarists'. To make a regular plural noun ending in 's' possessive, add an apostrophe at the end of the word, resulting in 'guitarists''.
Following standard punctuation rules ensures grammatical correctness.

Question 623Question →

The following passage is about the work of medieval scribes.

To preserve classical knowledge, medieval scribes spent countless hours copying texts in cold monasteries. They painstakingly reproduced scientific, philosophical, and literary manuscripts, despite the poor lighting and fatigue. Consequently, modern scholars must compare multiple versions of the same text. To reconstruct the original content as accurately as possible.

Which of the following options represents the correct punctuation for the underlined portion of the passage?

Show answer & explanation

Answer: text to reconstruct

Answer

text to reconstruct
The correct option removes the punctuation between the main clause and the infinitive phrase of purpose. In the sentence, the phrase beginning with 'to reconstruct' explains why modern scholars must compare the texts. Since this is an adverbial phrase rather than a separate independent clause, no punctuation is required to connect it to the main clause.

Step-by-Step Solution

1
Analyze the grammatical structure of the clauses surrounding the underlined portion.
The clause before the boundary ('Consequently, modern scholars must compare multiple versions of the same text') is independent. The phrase following the boundary ('To reconstruct the original content as accurately as possible') is an infinitive phrase.
Identifying clause boundaries and structures is necessary to determine the appropriate punctuation.
2
Evaluate the relationship between the independent clause and the following infinitive phrase.
The infinitive phrase acts as an adverbial modifier explaining the purpose of comparing the texts, meaning it is dependent on the main clause.
Understanding the function of the phrase helps determine if it should be separated by terminal punctuation.
3
Select the punctuation option that connects the phrase to the main clause without creating a fragment or comma splice.
Connecting them with no punctuation ('text to reconstruct') creates a single, grammatically correct sentence.
An infinitive phrase of purpose following a main clause does not require punctuation to separate it.

Key Concept

Identifying sentence fragments and choosing appropriate end-of-sentence punctuation to connect clauses and phrases.

Question 624Question →

The following sentences are from a draft of an essay about geologist Marie Tharp. To ensure the paragraph logically builds its claim that scientific data supported Tharp's hypothesis of a seafloor rift valley, in what order should the sentences be arranged?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The sentences should be ordered: Geologist Marie Tharp was convinced that a continuous rift valley ran down the center of the Atlantic Ocean...; To prove her hypothesis, Tharp meticulously plotted thousands of sonar soundings...; Her resulting maps revealed a distinct, V-shaped cleft...; Confronted with this precise correlation...
The correct paragraph structure starts by introducing Marie Tharp's hypothesis about the Mid-Atlantic Ridge rift valley. It then logically transitions to her methodology of plotting sonar soundings to prove her claim. Next, it introduces the specific details of the maps she produced, specifically the V-shaped cleft that correlated with earthquake data. Finally, it shows how this evidence resolved the conflict and convinced her colleague, validating plate tectonics.

Step-by-Step Solution

1
Identify the introductory sentence that establishes the claim.
The sentence introducing Marie Tharp's conviction about a continuous rift valley and her colleague's dismissal serves as the logical starting point.
A paragraph must first state the claim or hypothesis being investigated before detailing the evidence gathered to support it.
2
Determine the methodology or action taken to find evidence.
The sentence describing Tharp plotting thousands of sonar soundings must follow the introduction.
This establishes how she gathered the data necessary to prove her hypothesis.
3
Locate the specific supporting evidence derived from the methodology.
The sentence detailing the V-shaped cleft on the maps and its correlation with earthquake epicenters is placed next.
This provides the concrete details and evidence that resulted directly from the plotting process described in the previous step.
4
Find the concluding sentence that shows the impact of the evidence.
The sentence showing Heezen's acceptance of the rift valley when confronted with this correlation completes the paragraph.
This resolves the initial conflict introduced in the first sentence by demonstrating how the evidence supported and proved the claim.

Question 625Question →

The restoration of the ancient Roman aqueduct has sparked intense debate among architectural historians; the primary source of contention is the controversial materials used to reinforce the arches.

Which option best punctuates the underlined portion of the sentence?

Show answer & explanation

Answer: NO CHANGE

Answer

The correct option correctly uses a semicolon to join the two independent clauses, keeping the finite verb 'is' in the second clause.
The correct option correctly uses a semicolon to separate two independent clauses. The first clause, 'The restoration of the ancient Roman aqueduct has sparked intense debate among architectural historians,' and the second clause, 'the primary source of contention is the controversial materials used to reinforce the arches,' are both independent clauses capable of standing alone as complete sentences. A semicolon is the proper punctuation to join them without a coordinating conjunction.

Step-by-Step Solution

1
Identify the clause structure before the punctuation mark.
The clause 'The restoration of the ancient Roman aqueduct has sparked intense debate among architectural historians' is an independent clause because it contains a subject ('restoration') and a finite verb ('has sparked') and can stand alone as a complete sentence.
To determine the correct punctuation, you must first analyze the grammatical status of the preceding clause.
2
Analyze the grammatical structure of the clause following the punctuation mark for each option.
In the correct version, the clause 'the primary source of contention is the controversial materials used to reinforce the arches' contains a subject ('source') and a finite verb ('is'), making it an independent clause. In the version with 'being', the phrase lacks a finite verb, making it a fragment.
A semicolon can only join two independent clauses. If the second clause is a fragment, a semicolon cannot be used.
3
Evaluate the punctuation options to avoid comma splices or fragments.
Joining the two independent clauses with only a comma creates an ungrammatical comma splice. Joining them with a semicolon is correct.
Independent clauses must be joined by a semicolon, a period, or a comma accompanied by a coordinating conjunction.

Question 626Question →

The passage below contains a blank at the end of the first sentence. Which punctuation mark best fills the blank to correctly punctuate the end of the first sentence?

Fill in the blanks below

The archivist wondered whether the fragile parchment, which had been sealed in a lead box for centuries, would crumble upon exposure to the air, and if so, how the museum could possibly hope to preserve the faded ink This dilemma kept her awake at night, prompting her to consult with conservation specialists from around the world.
Show answer & explanation

Answer

A period (.)
The sentence is a declarative statement reporting what the archivist was wondering, which makes the clauses starting with 'whether' and 'how' indirect questions. Declarative sentences must end with a period.

Step-by-Step Solution

1
Analyze the structure of the sentence containing the blank.
The sentence begins with the main clause 'The archivist wondered.'
This main clause introduces a statement reporting a thought or question, rather than asking a question directly.
2
Determine the nature of the subsequent clauses introduced by 'whether' and 'how'.
The clauses 'whether the fragile parchment... would crumble' and 'how the museum could... preserve the faded ink' are indirect questions acting as noun clauses.
Indirect questions report what someone asked or wondered and do not perform the speech act of asking a direct question.
3
Identify the appropriate end-of-sentence punctuation mark.
Since the sentence is a declarative statement containing indirect questions, it must end with a period.
Declarative sentences are always punctuated with a period, even if they contain embedded indirect questions.

Key Concept

Declarative sentences that contain indirect questions must end with a period rather than a question mark.

Question 627Question →

As the storm approached the coast, the lone lighthouse's beacon flashed its warning to passing ships.

Which of the following is the correct spelling and punctuation of the underlined portion?

Show answer & explanation

Answer: lighthouse's beacon flashed its

Answer

The correct answer is the option that reads 'lighthouse's beacon flashed its', as it correctly uses the singular possessive noun 'lighthouse's' and the possessive pronoun 'its'.
The correct answer correctly features the singular possessive noun 'lighthouse's' to show that the beacon belongs to the single ('lone') lighthouse. It also uses the possessive pronoun 'its' to modify 'warning', showing that the warning belongs to the beacon.

Step-by-Step Solution

1
Analyze the context to determine whether the noun 'lighthouse' is singular or plural, and if it requires possession.
The word 'lone' indicates a single lighthouse. Since the beacon belongs to the lighthouse, we need the singular possessive form, which is 'lighthouse's'.
Singular possessive nouns are formed by adding an apostrophe and an 's' to the singular noun.
2
Determine if the word before 'warning' should be a contraction or a possessive pronoun.
The warning belongs to the beacon, so we need the possessive pronoun 'its'. The contraction 'it's' (meaning 'it is') would make the phrase 'flashed it is warning', which is grammatically incorrect.
Possessive pronouns like 'its' do not take apostrophes, whereas 'it's' is a contraction.

Question 628Question →

The following sentence contains two blanks that require words from the frequently confused pair 'flout' and 'flaunt'. Which word correctly fills each blank to maintain the proper meaning of the sentence?

Fill in the blanks below

Although the rebellious artist chose to the traditional rules of perspective, she did not her unconventional techniques merely to shock the critics.
Show answer & explanation

Answer

The correct words are 'flout' for the first blank and 'flaunt' for the second blank.
The verb 'flout' correctly completes the first blank because the artist is actively disregarding or defying established rules of perspective. The verb 'flaunt' correctly completes the second blank because it refers to the act of ostentatiously displaying or showing off her unconventional techniques.

Step-by-Step Solution

1
Examine the context of the first blank to identify the correct word choice.
The first blank describes the artist's action toward the 'traditional rules of perspective.' Since she is defying or disregarding these rules, the correct word is 'flout,' which means to mock or openly disregard a rule or law.
Understanding the semantic requirement of disregarding rules guides the choice of 'flout' over 'flaunt'.
2
Examine the context of the second blank to identify the correct word choice.
The second blank describes the artist not showing off her unconventional techniques to shock critics. The word 'flaunt' means to display ostentatiously or show off.
Understanding the semantic requirement of showing off or displaying ostentatiously guides the choice of 'flaunt' over 'flout'.

Key Concept

Distinguishing between the frequently confused verbs 'flout' (to openly disregard) and 'flaunt' (to display ostentatiously).

Question 629Question →

Organic architecture seeks to promote harmony between human habitation and the natural world. The architect Frank Lloyd Wright, who designed Fallingwater in 1935, revolutionized modern American home design by integrating structures directly into their surroundings. By building the house over a waterfall, he created a masterpiece that seamlessly blended art and nature.

Which of the following choices best punctuates the underlined portion?

Show answer & explanation

Answer: Frank Lloyd Wright, who designed Fallingwater in 1935,

Answer

The correct option is the one that has no comma before the name and places commas around the nonessential relative clause: 'Frank Lloyd Wright, who designed Fallingwater in 1935,'.
The correct answer does not place a comma between the noun 'architect' and the essential appositive 'Frank Lloyd Wright,' but it correctly sets off the nonessential relative clause 'who designed Fallingwater in 1935' with commas at both the beginning and the end.

Step-by-Step Solution

1
Determine if the name 'Frank Lloyd Wright' is an essential or nonessential appositive.
Since 'The architect' is a broad category, the specific name is essential to identify who is being discussed, so no comma should precede the name.
Essential (restrictive) elements should not be separated from their referent by commas.
2
Determine if the relative clause 'who designed Fallingwater in 1935' is essential or nonessential.
Because the subject has already been specifically identified by name, this descriptive clause is nonessential.
Nonessential (parenthetical) information must be completely set off by commas.
3
Select the option that matches these rules.
The option that leaves the space before the name unpunctuated and encloses the relative clause with two commas is correct.
This maintains the correct grammatical boundary for both restrictive and nonrestrictive elements.

Question 630Question →

Although the botanist collected samples from multiple orchids, she noted that the single rare flowers' vibrant color had lost it's intensity when kept in the shade. Which of the following is the best replacement for the underlined portion?

Show answer & explanation

Answer: flower's vibrant color had lost its

Answer

flower's vibrant color had lost its
The context specifies a 'single rare' orchid, which requires the singular possessive noun 'flower's'. Additionally, the possessive pronoun 'its' is required to show possession of the intensity, as the contraction 'it's' (meaning 'it is') is grammatically incorrect in this position.

Step-by-Step Solution

1
Determine if the noun modifying 'vibrant color' is singular or plural.
The context mentions a 'single rare' orchid, indicating that the noun must be singular possessive: 'flower's'.
An apostrophe followed by 's' is used to show possession for singular nouns.
2
Determine whether to use a contraction or a possessive pronoun for the word indicating ownership of intensity.
The word refers to the intensity belonging to the color, requiring the possessive pronoun 'its'.
The form 'it's' is a contraction of 'it is' or 'it has' and cannot be used to show possession.

Question 631Question →

The sentence below is missing a crucial punctuation mark between two independent clauses linked by a conjunctive adverb. What punctuation mark should be placed in the blank to correctly join these clauses?

Fill in the blanks below

The Svalbard Global Seed Vault, located on a remote Norwegian island, acts as a safety net for the world's crops consequently, the facility is built deep inside a sandstone mountain to withstand catastrophic events.
Show answer & explanation

Answer

A semicolon (;) must be used to separate the two independent clauses before the conjunctive adverb 'consequently'.
A semicolon is required to separate the two independent clauses because they are joined by the conjunctive adverb 'consequently'. A comma is insufficient because it results in a comma splice, and a period is incorrect because the transitional word 'consequently' is not capitalized and remains part of the same sentence flow.

Step-by-Step Solution

1
Identify the two clauses in the sentence and determine their relationship.
The first clause ('The Svalbard Global Seed Vault... acts as a safety net for the world's crops') and the second clause ('the facility is built deep inside... to withstand catastrophic events') are both independent clauses because they can stand alone as complete sentences.
Before deciding on the punctuation, we must analyze the structure of the clauses to see if they are independent or dependent.
2
Examine how the two independent clauses are connected.
The clauses are linked by the conjunctive adverb 'consequently', which introduces a cause-and-effect transition.
Recognizing the transitional word helps determine the punctuation style required.
3
Apply the appropriate punctuation rule for joining independent clauses with a conjunctive adverb.
When joining two independent clauses with a conjunctive adverb like 'consequently', a semicolon must precede the adverb, and a comma typically follows it.
Using a comma instead of a semicolon would result in a comma splice, while omitting punctuation entirely would create a run-on sentence.

Question 632Question →

For decades, art historians debated the authenticity of the Renaissance portrait. The local historian who discovered the forgotten letters, an expert on the artist’s early life recently published a groundbreaking study that resolved the mystery. This publication has sparked renewed interest in the painter's early works.

Which of the following choices best punctuates the underlined portion of the sentence?

Show answer & explanation

Answer: who discovered the forgotten letters, an expert on the artist’s early life, recently published

Answer

The correct option is the one that leaves the restrictive clause unpunctuated while properly enclosing the nonessential appositive phrase in commas.
The correct choice leaves 'who discovered the forgotten letters' without a preceding comma because it is a restrictive relative clause that identifies the specific historian. It also correctly places a pair of commas around 'an expert on the artist’s early life' because it is a nonessential appositive phrase providing extra detail.

Step-by-Step Solution

1
Determine if the clause 'who discovered the forgotten letters' is essential (restrictive) or nonessential (nonrestrictive) to the meaning of the sentence.
The clause is restrictive because it identifies which specific local historian is being discussed. Therefore, no comma should precede 'who'.
Restrictive elements define the preceding noun and are not set off by commas.
2
Determine if the appositive phrase 'an expert on the artist's early life' is essential or nonessential.
The phrase is nonessential because it provides supplementary information about the historian, who is already identified. It must be enclosed in commas.
Nonessential appositives must be set off by a pair of commas to show they are parenthetical.

Question 633Question →

Josephine’s Invention

[1]
In the late nineteenth century, Josephine Cochrane, a wealthy socialite from Illinois, grew frustrated with a common household problem. Although she did not wash dishes herself, her servants frequently chipped her fine heirloom china while cleaning it. Determined to find a better solution, Cochrane resolved to build a machine that could wash dishes faster and more safely than human hands.

[2]
Working in a shed behind her home, Cochrane designed a machine that used high water pressure rather than scrubbers to clean. She measured the dishes first, constructing wire compartments tailored to fit plates, cups, and saucers. These compartments were placed inside a copper boiler, which rotated while hot, soapy water was sprayed from the bottom. Cochrane patented her invention in 1886, naming it the Cochrane Dishwasher.

[3]
Initially, Cochrane’s invention was not designed for the average home, which lacked the plumbing and hot water heaters necessary to run the machine. Instead, she found success selling her large-scale washers to hotels, restaurants, and hospitals, where efficiency and sanitation were paramount. Cochrane’s design laid the foundation for the modern household appliance that is now common in kitchens worldwide.

Suppose the writer’s goal had been to write an essay that describes the technical and mechanical difficulties Cochrane encountered while building her first prototype. Would this essay successfully fulfill that goal?

Show answer & explanation

Answer: No, because the essay focuses on the motivation behind Cochrane's invention and its early commercial applications rather than detailing the technical setbacks she faced while building the machine.

Answer

No, because the essay focuses on the motivation behind Cochrane's invention and its early commercial applications rather than detailing the technical setbacks she faced while building the machine.
The correct answer is the option stating that the essay does not meet the goal because it focuses on Cochrane's motivations and commercial applications rather than technical setbacks. The essay explains why Cochrane decided to build the machine and where it was sold, but never mentions any mechanical difficulties or engineering failures during the prototyping phase.

Step-by-Step Solution

1
Analyze the writer's proposed goal.
The goal is to write an essay that describes the technical and mechanical difficulties Cochrane encountered while building her first prototype.
Understanding the proposed goal is necessary to evaluate if the essay meets it.
2
Evaluate the passage content against the proposed goal.
The passage discusses why Cochrane wanted to build the machine (servants chipping china), the general design (water pressure and copper boiler), and its early commercial use (hotels and restaurants). It does not mention any technical setbacks, design failures, or mechanical obstacles encountered during the prototyping process.
Comparing the essay's content with the goal determines if the essay succeeds or fails to meet that goal.
3
Select the option that correctly states whether the goal was met and provides the accurate reason.
The essay did not meet the goal (No). The correct reason is that the essay focuses on her motivations and commercial applications rather than her prototyping setbacks.
Identifying the correct Yes/No direction and the corresponding logical explanation leads to the correct answer.

Question 634Question →

During a stormy summer in Switzerland, Mary Shelley began writing her famous novel *Frankenstein*. The young author, who was only eighteen at the time, drew inspiration from conversations about galvanism and scientific discoveries. Today, the book is celebrated as a pioneering masterpiece of science fiction.

Which choice is the correct punctuation for the underlined portion of the sentence?

Show answer & explanation

Answer: NO CHANGE

Answer

NO CHANGE
The correct choice is 'NO CHANGE' because the clause 'who was only eighteen at the time' is a nonessential relative clause. It provides extra, parenthetical information about the young author. Nonessential clauses must be set off from the rest of the sentence by a matching pair of commas—one before the clause and one after it.

Step-by-Step Solution

1
Identify whether the underlined clause 'who was only eighteen at the time' is essential (restrictive) or nonessential (nonrestrictive) to the meaning of the sentence.
The clause is nonessential because the subject 'The young author' is already clearly identified, and removing the clause does not change the core meaning of the sentence.
Nonessential elements must be set off from the rest of the sentence using commas, dashes, or parentheses.
2
Punctuate the nonessential clause correctly by surrounding it with a pair of commas.
The clause starts after 'author' and ends after 'time', requiring a comma in both locations: ', who was only eighteen at the time,'.
Enclosing a nonessential clause with a matching pair of commas correctly separates it from the main clause without disrupting the subject-verb connection.

Question 635Question →

The following passage is about the history of Manhattan's street layout.

Manhattan's Grid

[1]
In the early nineteenth century, New York City was growing rapidly, yet its street layout was a chaotic jumble of narrow, winding pathways. To bring order to this expanding metropolis, the state legislature appointed a commission in 1807 to design a new street system. The resulting proposal, known as the Commissioners' Plan of 1811, introduced the iconic rectangular grid of streets and avenues that defines Manhattan today.

[2]
The planners prioritized practicality over aesthetic elegance. They rejected circular designs or diagonal boulevards, which were popular in European capitals, in favor of right-angled intersections. This layout maximized the utility of building lots and simplified the buying and selling of real estate. While some critics argued that the grid was monotonous, its efficiency facilitated the city's commercial explosion.

[3]
Today, the grid remains the structural backbone of Manhattan. It has proven remarkably adaptable, accommodating millions of residents, skyscrapers, and transit systems that the original planners could scarcely have imagined. Although Central Park was later carved out of the grid to provide green space, the basic rectangular network continues to shape the daily flow of life in the city.

Suppose the writer's goal had been to write an essay that traces the transition of New York City from a chaotic trading post to a global financial capital. Would this essay accomplish this goal?

Show answer & explanation

Answer: No, because the essay focuses on the design, implementation, and long-term adaptation of Manhattan's street grid rather than tracing the city's broader economic and financial history.

Answer

No, because the essay focuses on the design, implementation, and long-term adaptation of Manhattan's street grid rather than tracing the city's broader economic and financial history.
The correct answer is correct because the essay restricts its focus to the origin, design, and adaptability of Manhattan's street layout. It does not provide the historical context or details necessary to trace New York City's evolution from a trading post to a global financial capital.

Step-by-Step Solution

1
Analyze the hypothetical goal proposed in the question stem.
The goal is to write an essay that traces the transition of New York City from a chaotic trading post to a global financial capital.
Understanding the specific requirements of the hypothetical goal is necessary to evaluate the essay against it.
2
Analyze the actual content and main focus of the provided passage.
The passage focuses on the history, design philosophy, and long-term physical adaptability of Manhattan's 1811 grid layout.
Comparing the actual content of the essay to the proposed goal determines whether the goal has been met.
3
Evaluate whether the essay fulfills the hypothetical goal and select the correct reasoning.
The essay does not fulfill the goal because its focus is limited to the physical street grid rather than the city's broader economic and financial history.
This step matches the evaluation to the correct Yes/No direction and the corresponding logical explanation.

Although the two research teams agreed on the single fossil's age, they disagreed on the specimens' origin and it's classification within the dinosaur family tree.

Which choice most effectively and grammatically completes the underlined portion of the sentence?

Show answer & explanation

Answer: specimen's origin and its

Answer

specimen's origin and its
The correct option correctly uses the singular possessive noun 'specimen's' because the context refers to a single fossil. It also correctly uses the possessive pronoun 'its' to show that the classification belongs to the specimen, avoiding the contraction 'it's' (which means 'it is').

Step-by-Step Solution

1
Determine if the noun modifying 'origin' should be singular or plural.
The sentence specifies 'the single fossil's age,' which means only one specimen is being discussed. Therefore, the singular possessive form 'specimen's' must be used.
To show ownership or association for a singular noun, add an apostrophe followed by an 's'.
2
Determine if a possessive pronoun or a contraction is needed before 'classification.'
The word modifies 'classification' to show that the classification belongs to the specimen, requiring the possessive pronoun 'its'. The contraction 'it's' (meaning 'it is' or 'it has') would create an ungrammatical phrase ('it is classification').
Possessive pronouns do not use apostrophes, whereas apostrophes in pronouns indicate contractions.
3
Combine the correct singular possessive noun and the correct possessive pronoun.
The combined phrase is 'specimen's origin and its'.
This is the only combination that is grammatically correct and contextually appropriate.

During the excavation, the team discovered a well-preserved *Triceratops* skeleton, but the fossils' tail was missing it's unique defensive spikes.

Which choice most effectively corrects the underlined portion of the sentence?

Show answer & explanation

Answer: fossil's tail was missing its

Answer

fossil's tail was missing its
The sentence describes a single skeleton ('a well-preserved Triceratops skeleton'), which means the singular possessive form 'fossil's' is required. Additionally, the sentence needs the possessive pronoun 'its' to show ownership of the defensive spikes. The option 'fossil's tail was missing its' is correct because it satisfies both of these conditions.

Step-by-Step Solution

1
Determine if the noun 'fossil' should be singular or plural, and possessive or not.
The sentence mentions 'a well-preserved Triceratops skeleton', which indicates a single fossil. The tail belongs to this fossil, so we need the singular possessive form 'fossil's'.
Establishing the singular versus plural context determines where the apostrophe belongs.
2
Determine if the pronoun referring to the fossil should be a contraction or a possessive.
The sentence refers to the fossil's own defensive spikes, which requires the possessive pronoun 'its'. The contraction 'it's' (short for 'it is' or 'it has') does not make sense in this context.
Differentiating between the homophones 'its' and 'it's' is necessary for proper grammatical conventions.
3
Identify the option that correctly combines both grammatical forms.
The choice containing 'fossil's tail was missing its' is correct.
This option contains both 'fossil's' and 'its' correctly.

During a winter trip to New York City in 1902, Mary Anderson observed a trolley driver struggle to see through a sleet-covered windshield. The driver had to repeatedly open his window, leaning out into the freezing air to wipe the glass by hand. Upon returning to Alabama, Anderson sketched her solution: a wooden lever inside the vehicle connected to a rubber blade on the outside. [X]

Resorting to the passage above, the writer wants to add a sentence at the indicated point [X] that emphasizes the immediate skepticism Anderson's invention faced despite its practical utility. Which choice best accomplishes this goal?

Show answer & explanation

Answer: Although the design was highly effective, potential buyers rejected the patent because they believed the moving blade would distract drivers.

Answer

The correct option establishes the contrast between the invention's utility and the skepticism it encountered, stating that potential buyers rejected the effective design due to concerns over driver distraction.
The correct choice successfully meets both parts of the rhetorical goal: it highlights the device's practical utility by calling the design 'highly effective' and emphasizes the immediate skepticism it faced by stating that potential buyers rejected it out of fear that the moving blade would distract drivers. Furthermore, this option is grammatically correct.

Step-by-Step Solution

1
Analyze the prompt to identify the specific rhetorical goals requested.
The added sentence must satisfy two requirements: emphasize the practical utility of the invention and emphasize the immediate skepticism or rejection it faced.
This establishes clear criteria to evaluate the suitability of each option.
2
Evaluate the choices for grammatical correctness.
The choice stating that firms refused to license the patent because they feared the blade would distract drivers contains a comma splice, incorrectly linking two independent clauses with a comma and no coordinating conjunction.
Eliminating grammatically incorrect options narrows the choices to valid sentences.
3
Assess the remaining grammatically correct choices against the rhetorical goal.
The choices detailing the patent's 1903 approval and the simplicity of the solution fail to mention skepticism. The choice stating that potential buyers rejected the effective patent due to distraction concerns is grammatically correct and matches the rhetorical goal perfectly.
This isolates the choice that fulfills all pedagogical and structural criteria.

Show answer & explanation

Answer

A semicolon (;) must be used to join the two independent clauses.
A semicolon is required to join the two independent clauses because they are closely related in meaning and there is no coordinating conjunction to connect them.

Step-by-Step Solution

1
Analyze the structure of the two clauses on either side of the blank.
The clause before the blank ('The local bakery is famous for its sourdough bread') and the clause after the blank ('customers line up down the block every morning to buy a fresh loaf') are both independent clauses.
Each clause contains a subject and a verb and expresses a complete thought, meaning each could stand alone as a complete sentence.
2
Determine the appropriate punctuation to connect two independent clauses without a coordinating conjunction.
A semicolon is the correct punctuation mark to join these two clauses.
A semicolon is used to connect two closely related independent clauses that are not joined by a coordinating conjunction (such as 'and', 'but', or 'so').

Key Concept

A semicolon is used to link two independent clauses that are closely related in thought.

The following five sentences are taken from a draft of an essay about the decipherment of Bronze Age scripts. Arrange these sentences in the most logical sequence so that each claim is immediately followed by its supporting evidence or details.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The sentences should be ordered: (1) introduction of the traditional view of Linear B, (2) explanation of the pictographic basis for this consensus, (3) presentation of Michael Ventris's counter-hypothesis, (4) description of the specific geographical evidence validating his theory, and (5) the conclusion regarding the historical impact of this geographical link.
The paragraph begins with the traditional claim about Linear B, followed by the evidence supporting that view. It then introduces Ventris's counter-claim, followed by the specific evidence validating his claim, and concludes with the overall impact of that evidence.

Step-by-Step Solution

1
Identify the introductory sentence.
The sentence introducing Linear B and the initial assumption that it was non-Greek must start the paragraph.
It sets the context and defines the main subject of the paragraph.
2
Locate the evidence supporting the initial assumption.
The sentence starting with 'This consensus' logically follows the introduction.
It provides the specific evidence (pictographic characters not resembling Greek) that supports the initial claim of a non-Greek origin.
3
Identify the transition to the counter-hypothesis.
The sentence starting with 'However' introducing Ventris's hypothesis comes next.
It contrasts with the traditional consensus and introduces a new claim.
4
Find the evidence supporting the counter-hypothesis.
The sentence explaining how Ventris 'validated this controversial theory' follows the hypothesis.
It directly supports Ventris's claim with specific details (matching syllables to towns like Knossos and Amnisos).
5
Determine the concluding sentence.
The sentence starting with 'This geographical link' ends the paragraph.
It references the 'geographical link' established in the previous sentence and sums up the significance of the decipherment.
