Question 561Question →

In the passage below, fill in each blank with the correct choice from the homophones 'discreet' and 'discrete' to ensure semantic and grammatical correctness.

Fill in the blanks below

To protect the privacy of the study's participants, the research team made a effort to keep all identifying data confidential, analyzing the information only as data points that could not be linked back to specific individuals.
Show answer & explanation

Answer

The first blank must be filled with 'discreet' and the second blank must be filled with 'discrete'.
The correct response uses 'discreet' in the first blank because the context of protecting participant privacy requires a word meaning cautious, confidential, or circumspect. It uses 'discrete' in the second blank because describing data points that are unlinked and separate requires a word meaning distinct or individual.

Step-by-Step Solution

1
Determine the required meaning for the first blank based on the surrounding context.
The first blank describes an 'effort to keep all identifying data confidential' to protect privacy. This context requires an adjective meaning cautious, wary, or respecting privacy. The correct spelling for this meaning is 'discreet'.
Analyzing the first part of the sentence establishes the semantic demand for confidentiality and prudence.
2
Determine the required meaning for the second blank based on the surrounding context.
The second blank describes 'data points' that are analyzed individually and cannot be linked back to specific individuals. This context requires an adjective meaning distinct, separate, or discontinuous. The correct spelling for this meaning is 'discrete'.
Analyzing the second part of the sentence establishes the semantic demand for separate, individual units of data.

Key Concept

Distinguishing between the homophones 'discreet' (showing prudence, caution, or keeping secrets) and 'discrete' (constituting a separate, distinct, or individual entity).

Question 562Question →

In the early twentieth century, the verification of Einstein's general theory of relativity hinged on observing the deflection of starlight during a solar eclipse. Arthur Eddington, who captured the photographic evidence that confirmed the theory, was an English astrophysicist who led the crucial 1919 expedition to the island of Príncipe. This landmark observation catapulted Einstein to global fame and revolutionized modern physics.

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

Show answer & explanation

Answer: NO CHANGE

Answer

NO CHANGE
The correct option correctly uses a pair of commas to set off the nonessential relative clause beginning with 'who captured' and ending with 'theory' from the main sentence, while correctly avoiding commas around the restrictive clause 'that confirmed the theory'.

Step-by-Step Solution

1
Identify whether the underlined relative clause is essential (restrictive) or nonessential (nonrestrictive) to the meaning of the sentence.
The clause 'who captured the photographic evidence that confirmed the theory' modifies the proper noun 'Arthur Eddington.' Because proper nouns uniquely identify a person, any relative clause modifying them is nonessential.
Nonessential elements must be set off from the rest of the sentence with punctuation (typically commas).
2
Determine the correct punctuation to set off the nonessential clause.
A pair of commas must enclose the nonessential clause: one immediately before it (after 'Eddington') and one immediately after it (after 'theory').
Failing to include both commas leaves a punctuation mark dangling and breaks the syntactic flow of the main sentence.
3
Evaluate the restrictive clause 'that confirmed the theory' nested inside the nonessential clause.
This nested clause is restrictive because it specifies which photographic evidence is being discussed. Therefore, it must not be separated from 'evidence' by commas.
Commas should never isolate a restrictive clause from the noun it modifies.

Question 563Question →

Though the two companies announced a mutual merger, each board's members defended it's own autonomy during the final negotiations.

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

Show answer & explanation

Answer: board's members defended its

Answer

board's members defended its
The correct option correctly applies the singular possessive form 'board's' to agree with the singular modifier 'each', and it uses the possessive pronoun 'its' (without an apostrophe) to refer to the singular noun 'board'.

Step-by-Step Solution

1
Determine whether 'board' should be singular or plural possessive.
Since the sentence uses the word 'each' to refer to the individual boards, the noun must be singular. To show possession of the members, we use the singular possessive form, 'board's'.
The adjective 'each' always modifies a singular noun.
2
Determine the correct pronoun to replace 'it's'.
The pronoun refers back to the singular noun 'board' and must show possession of 'autonomy'. The singular possessive pronoun is 'its'.
'It's' is a contraction for 'it is' or 'it has', and 'its'' is a non-existent spelling. A possessive pronoun is needed here.
3
Combine the correct noun form and pronoun form to choose the correct replacement.
The correct combination is 'board's' and 'its'.
This option resolves both the noun punctuation error and the pronoun homophone error.

Question 564Question →

[1] In the late nineteenth century, Marianne North defied Victorian conventions by traveling alone to document the world's flora through her vibrant oil paintings. [2] Unlike contemporary botanists who relied on dried, pressed specimens, North insisted on painting plants in their natural environments. [3] Her vast body of work, which includes over 800 paintings, was not only artistically remarkable but also scientifically invaluable. [4] Indeed, she captured details of plant physiology that were lost in dried museum specimens, such as ________.

The writer wants to revise the underlined portion of sentence 4 to provide the most specific, concrete visual details that illustrate the plant physiology details captured by North. Given that all the choices are true, which one best accomplishes this goal?

Show answer & explanation

Answer: the intricate, pitcher-shaped leaves of *Nepenthes northiana*, showcasing their crimson speckles and waxy rims.

Answer

the intricate, pitcher-shaped leaves of *Nepenthes northiana*, showcasing their crimson speckles and waxy rims.
The correct choice provides specific, concrete visual details—'intricate, pitcher-shaped leaves' and 'crimson speckles and waxy rims'—that directly illustrate the plant physiology details captured by North.

Step-by-Step Solution

1
Analyze the prompt to identify the specific rhetorical goal.
The goal is to find the option that provides the most specific, concrete visual details illustrating the details of plant physiology.
This establishes the criteria for evaluating the choices.
2
Evaluate the choices for grammatical correctness.
The option beginning with 'the structures of tropical flowers' is a comma splice, and the option starting with 'although' is a sentence fragment. Both are grammatically incorrect.
Eliminating grammatically incorrect options narrows the choices to those that are syntactically sound.
3
Compare the remaining grammatically correct options against the rhetorical goal.
The option mentioning 'several plants' is vague and geographical, whereas the option describing the 'intricate, pitcher-shaped leaves... crimson speckles and waxy rims' provides specific, concrete visual details of plant physiology.
Selecting the option that best fulfills the specified rhetorical goal determines the correct answer.

Question 565Question →

Although the committee members were impressed by the design of the new library, they voiced concerns about it's visitors' access to the parking options, which were already crowded with hundreds of vehicles.

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

Show answer & explanation

Answer: its visitors'

Answer

The correct option is the one that reads "its visitors'".
The correct answer correctly uses "its" as the possessive pronoun for the singular noun "library" and "visitors'" as the plural possessive noun. The possessive pronoun "its" never takes an apostrophe, and placing the apostrophe after the "s" in "visitors'" correctly shows that the access belongs to multiple visitors, matching the plural context of the sentence.

Step-by-Step Solution

1
Determine the correct possessive form for the pronoun referring to the library.
The pronoun refers to the singular noun "library." The possessive form of "it" is "its" without any apostrophe. The spelling "it's" is a contraction for "it is" or "it has," and the spelling "its'" is not a valid English word.
Choosing the correct possessive pronoun avoids homophone and spelling confusion.
2
Determine whether the noun "visitor" should be singular or plural, and possessive or not.
The context mentions "hundreds of vehicles," indicating there are multiple visitors. The access belongs to these visitors, requiring a plural possessive noun: "visitors'". Placing the apostrophe before the "s" ("visitor's") would incorrectly make it singular possessive.
Applying the correct plural possessive punctuation fits the context of the sentence.

Question 566Question →

The newly discovered cave system contains unique crystalline formations, furthermore, it houses a previously unknown species of blind cave fish.

Which of the following choices best replaces the underlined portion?

Show answer & explanation

Answer: formations; furthermore, it

Answer

The correct option is 'formations; furthermore, it' because it correctly uses a semicolon to separate two independent clauses connected by the transitional adverb 'furthermore'.
The correct option uses a semicolon to separate two independent clauses linked by the transitional adverb 'furthermore'. When two independent clauses are joined by a conjunctive adverb, a semicolon must precede the adverb, and a comma must follow it.

Step-by-Step Solution

1
Identify the two clauses in the sentence.
The clauses are 'The newly discovered cave system contains unique crystalline formations' and 'it houses a previously unknown species of blind cave fish'.
Determining clause type helps choose the correct punctuation.
2
Determine if the clauses are independent or dependent.
Both clauses can stand alone as complete thoughts, meaning they are both independent clauses.
Two independent clauses must be joined by a semicolon, a colon, or a comma plus a coordinating conjunction.
3
Evaluate the role of the transitional adverb 'furthermore'.
Since 'furthermore' is a conjunctive adverb linking two independent clauses, it requires a semicolon before it and a comma after it.
This establishes proper transition punctuation and avoids a comma splice.

Key Concept

Using semicolons to connect independent clauses linked by a transitional adverb.
Question 567Question →

Monarch butterflies migrate thousands of miles south every autumn; they spend the winter in the forests of central Mexico.

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

Show answer & explanation

Answer: autumn; they

Answer

The correct answer is the option that reads 'autumn; they'.
The correct option is the one that leaves the sentence unchanged. The sentence is composed of two independent clauses: 'Monarch butterflies migrate thousands of miles south every autumn' and 'they spend the winter in the forests of central Mexico.' Because both clauses are complete thoughts that could stand alone as sentences, a semicolon is the grammatically correct way to join them without a coordinating conjunction.

Step-by-Step Solution

1
Identify the two clauses being joined in the sentence.
The first clause is 'Monarch butterflies migrate thousands of miles south every autumn,' and the second clause is 'they spend the winter in the forests of central Mexico.'
We must determine whether the clauses are independent or dependent to apply the correct punctuation rule.
2
Analyze the grammatical structure of both clauses.
Both clauses contain a subject and a verb, express a complete thought, and can stand alone as separate sentences, meaning they are both independent clauses.
Knowing that both clauses are independent helps narrow down the acceptable ways to connect them.
3
Determine the appropriate punctuation to connect the two independent clauses.
Since there is no coordinating conjunction (like 'and' or 'but') to link them, a semicolon is the correct punctuation mark to connect the two independent clauses.
This correctly resolves the transition without introducing comma splices or fragment errors.

Key Concept

Using a semicolon to link two closely related independent clauses without a coordinating conjunction.
Question 568Question →

In an effort to protect the endangered wetland habitat, the local conservation board voted to prescribe any commercial development within a two-mile radius of the estuary.

Which choice best fits the context of the sentence?

Show answer & explanation

Answer: proscribe

Answer

The correct choice is 'proscribe'.
The correct choice is 'proscribe' because it means to forbid or ban, which fits the context of protecting the endangered wetland habitat. The verb is transitive and correctly takes the direct object 'any commercial development' without a preposition.

Step-by-Step Solution

1
Identify the context and the intended meaning of the underlined word.
The sentence describes a conservation board acting to protect a habitat by limiting commercial development. Therefore, the board wants to forbid or ban development.
Understanding the context allows us to determine the semantic role of the target word.
2
Evaluate the meaning of 'prescribe' versus 'proscribe'.
'Prescribe' means to recommend or establish a rule. 'Proscribe' means to outlaw, forbid, or ban.
Distinguishing between these frequently confused homophones is necessary to choose the word with the correct meaning.
3
Check for grammatical correctness and idiomatic usage.
The verb 'proscribe' is transitive and directly takes the noun phrase 'any commercial development' as its object. The preposition 'against' is unnecessary and ungrammatical.
Ensuring the chosen word fits the syntactic structure of the sentence is crucial for grammar assessment.

Question 569Question →

Passage:
The atmospheric pressure on Venus is ninety times greater than that of Earth; therefore, sending probes to explore the planetary surface requires heavily armored landers that can withstand the crushing environment for only a few hours.

Which of the following options is the most effective punctuation for the underlined portion of the sentence?

Show answer & explanation

Answer: Earth; therefore, sending probes

Answer

The correct option is the one that uses a semicolon followed by 'therefore' and a comma to join the two independent clauses.
The original sentence correctly uses a semicolon to connect two closely related independent clauses. The conjunctive adverb 'therefore' is properly preceded by a semicolon and followed by a comma, establishing a logical cause-and-effect relationship without creating a comma splice or run-on sentence.

Step-by-Step Solution

1
Identify the clauses surrounding the underlined portion.
The first clause ('The atmospheric pressure on Venus is ninety times greater than that of Earth') and the second clause ('sending probes to explore the planetary surface requires heavily armored landers...') are both independent clauses capable of standing alone as complete sentences.
To determine the correct punctuation, we must first assess whether the clauses are independent or dependent.
2
Evaluate the role of the transitional word 'therefore'.
'Therefore' is a conjunctive adverb, not a coordinating conjunction.
Conjunctive adverbs require a semicolon (or a period) before them and a comma after them when they are used to connect two independent clauses.
3
Analyze the choices to find the one that avoids a comma splice or a sentence fragment.
The original punctuation ('Earth; therefore, sending probes') correctly employs a semicolon before the conjunctive adverb and a comma after it, maintaining two complete, properly connected sentences.
Other choices introduce grammatical errors such as comma splices or dependent clause fragments.

Question 570Question →

Although the symphony hired only one guest conductor for the autumn season, the conductors' critique of they're final rehearsal was met with silent hostility from the musicians.

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

Show answer & explanation

Answer: conductor's critique of their

Answer

The correct option is the one that reads 'conductor's critique of their'.
The correct choice is the one that uses the singular possessive noun 'conductor's' and the possessive pronoun 'their'. The sentence states that the symphony hired 'only one guest conductor,' which means the noun must be singular possessive ('conductor's'). Additionally, because 'final rehearsal' is a noun phrase, the possessive pronoun 'their' is required to modify it, rather than the contraction 'they're' (which means 'they are').

Step-by-Step Solution

1
Determine whether the noun indicating possession should be singular or plural based on the context.
The clause states the symphony hired 'only one guest conductor,' meaning the singular possessive form 'conductor's' must be used instead of the plural possessive 'conductors'.
This establishes the correct placement of the apostrophe before the 's'.
2
Determine whether a contraction or possessive pronoun is required before the noun phrase 'final rehearsal'.
The context requires the possessive pronoun 'their' to modify 'final rehearsal' rather than the contraction 'they're' (which stands for 'they are').
This prevents a grammatical error and ensures the sentence makes logical sense.

Key Concept

Question 571Question →

In 1962, biologist Rachel Carson published her landmark book *Silent Spring*. The book , which warned of the dangers of chemical pesticides, helped launch the modern environmental movement. Today, this work is widely considered a turning point in conservation history.

Which choice best punctuates the underlined portion of the passage?

Show answer & explanation

Answer: NO CHANGE

Answer

The choice that makes no changes to the underlined portion is correct because it correctly uses a pair of commas to set off the nonessential relative clause.
The correct choice keeps the sentence as written. The clause 'which warned of the dangers of chemical pesticides' is a nonessential relative clause that provides extra information about the book. Because the book's title is already specified, the clause is not needed to identify the book. Therefore, it must be set off with a matching pair of commas.

Step-by-Step Solution

1
Determine if the underlined clause is essential or nonessential to the meaning of the sentence.
The clause 'which warned of the dangers of chemical pesticides' is nonessential because the book's title is already specified, making the clause parenthetical.
Nonessential information must be set off from the rest of the sentence with commas.
2
Evaluate the punctuation surrounding the nonessential clause.
A pair of commas is required, one before 'which' and one after 'pesticides'.
Omitting one of the commas or using a semicolon creates grammatical errors.

Question 572Question →

The following passage is about the ecological effects of reintroducing wolves to Yellowstone National Park.

Restoring the Balance

[1]
In 1995, conservationists reintroduced gray wolves to Yellowstone National Park, ending a seventy-year absence of the apex predator. During the wolves’ absence, the park's elk population had soared, leading to severe overgrazing of young willow, aspen, and cottonwood trees along valley bottoms. Lacking competition and predators, the elk had stripped the riverbanks bare, causing significant erosion and altering the local ecosystem.

[2]
The return of the wolves quickly initiated a phenomenon known as a trophic cascade. As wolves hunted the elk, the herbivores' behavior shifted; they began avoiding low-lying areas where they could be easily cornered. Consequently, the vegetation along the riverbanks began to recover. Willows and aspens grew taller, providing shade that cooled the water, which in turn benefited native trout species.

[3]
With the regrowth of trees, songbirds returned to the valleys, and beavers found the materials they needed to build dams. Beaver ponds created wetlands that supported insects, amphibians, and waterfowl. By modifying the behavior of a single herbivore, the wolves indirectly reshaped the physical geography and biological diversity of the entire park, proving that predators are essential to maintaining healthy ecosystems.

Suppose the writer’s goal had been to write an essay that explains how the reintroduction of a predator can restore biodiversity and physically alter an ecosystem's landscape. Would this essay accomplish that goal?

Show answer & explanation

Answer: Yes, because it details how the wolves' return altered elk behavior, allowing riverbank vegetation to recover and beavers to create new wetland habitats.

Answer

Yes, because it details how the wolves' return altered elk behavior, allowing riverbank vegetation to recover and beavers to create new wetland habitats.
The essay successfully meets the goal because it details how the reintroduction of gray wolves altered elk behavior, which led to the recovery of riverbank plants (restoring biodiversity) and allowed beavers to construct dams that created wetlands (physically altering the landscape).

Step-by-Step Solution

1
Analyze the writer's goal stated in the prompt.
The goal is to explain how a reintroduced predator restores biodiversity and physically alters the landscape.
To evaluate if the essay meets the goal, we must first understand the criteria for success.
2
Examine the passage to see if the criteria are met.
The predator (gray wolf) is reintroduced. Biodiversity restoration is shown through the return of vegetation, songbirds, trout, and wetland species. Physical alteration is shown through recovered riverbank vegetation and beaver dams creating new wetlands.
This determines if the overall answer should be Yes or No.
3
Match the correct Yes/No direction with the most accurate reasoning.
The option stating that the essay succeeds because it details wolf-driven changes in elk behavior, vegetation recovery, and beaver wetland creation matches the passage content perfectly.
This identifies the correct choice among the Yes options.

Question 575Question →

The following sentences, when ordered logically, form a cohesive paragraph discussing the ancient Maya water management system in Tikal. What is the most logical sequence of these sentences to support the claim with clear functional evidence?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence of sentences is: 'To sustain a population of tens of thousands, the ancient Maya city of Tikal relied on a sophisticated system of human-made reservoirs to survive the region's intense dry seasons.', followed by 'These paved basins, constructed by plastering natural depressions and quarry pits, were designed to collect and store millions of gallons of rainwater during the wet months.', then 'During the subsequent months of drought, this stored water was released through a network of canals to irrigate agricultural fields and supply the city's residents.', and finally 'Archaeological excavations have confirmed that this system maintained clean drinking water by utilizing sand filters at the entry points of the main reservoirs.'
The correct ordering begins with the central claim that Tikal relied on human-made reservoirs to survive dry seasons. Next, the sentence defining these reservoirs as 'paved basins' that collect rainwater must follow because it defines the infrastructure. Then, the sentence describing how 'this stored water' is distributed during the drought follows to complete the system's functional timeline. Finally, the archaeological evidence of sand filtration concludes the paragraph by verifying the functionality and cleanliness of the system.

Step-by-Step Solution

1
Identify the introductory claim that sets the topic for the paragraph.
The sentence introducing Tikal's reliance on reservoirs to survive dry seasons.
It introduces the central claim about Tikal's water management without requiring external context.
2
Identify the sentence that defines or elaborates on the reservoirs mentioned in the introduction.
The sentence beginning with 'These paved basins'.
The demonstrative pronoun 'These' links 'paved basins' directly to the 'human-made reservoirs' in the first sentence.
3
Trace the chronological and functional flow of the water storage system.
The sentence describing the release of water during the dry months.
After describing how the basins collected water in the wet months, the text must transition to how 'this stored water' was distributed during the drought.
4
Place the validating scientific evidence that supports the claim of viability.
The sentence discussing archaeological excavations and sand filtration.
It offers concrete scientific verification for the effectiveness of the system described in the previous sentences.

Question 577Question →

The following passage is about the origin of the chocolate chip cookie.

[1] In 1938, Ruth Wakefield, co-owner of the Toll House Inn in Massachusetts, made a culinary decision that changed baking history. While preparing a batch of chocolate cookies, she realized she was out of baker's chocolate. Improvising, she chopped up a bar of semi-sweet chocolate, expecting it to melt entirely into the dough during baking.

[2] To her surprise, the chocolate bits did not melt completely; instead, they softened into distinct, gooey pockets of chocolate within the cookie. The guests at the inn praised the new creation, which she named the Toll House Chocolate Crunch Cookie. Its popularity grew rapidly, prompting a partnership with Nestlé to print her recipe on their packaging.

[3] Today, the chocolate chip cookie remains one of the most popular desserts in the United States. Wakefield’s invention demonstrates how an unexpected change in a recipe can lead to a beloved culinary tradition.

Suppose the writer's goal had been to write an essay focusing on the historical origin and accidental creation of the chocolate chip cookie. Does this essay successfully fulfill that goal?

Show answer & explanation

Answer: True

Answer

Step-by-Step Solution

1
Identify the writer's hypothetical goal mentioned in the prompt.
The goal is to focus on the historical origin and accidental creation of the chocolate chip cookie.
This establishes the criteria for evaluating the essay's success.
2
Analyze the main theme and content of the provided passage.
The passage describes Ruth Wakefield in 1938 running out of baker's chocolate, chopping up semi-sweet chocolate, and finding that the pieces didn't melt as expected, thus inventing the chocolate chip cookie.
This determines if the actual content matches the stated goal.
3
Compare the hypothetical goal with the actual content of the passage.
The actual content directly aligns with the goal of detailing the historical origin and accidental creation of the cookie.
Evaluating this alignment determines the final answer.

Question 578Question →

Deep within the Guatemalan rainforest, archeologists have discovered a vast network of Mayan ruins previously hidden by dense canopy. LiDAR; a laser mapping technology, has revealed structures that were previously invisible under the forest floor. This groundbreaking data has revolutionized our understanding of pre-Columbian civilization.

Which choice best punctuates the underlined portion of the sentence?

Show answer & explanation

Answer: LiDAR, a laser mapping technology, has revealed structures that were previously invisible

Answer

LiDAR, a laser mapping technology, has revealed structures that were previously invisible
The correct answer properly encloses the nonessential appositive phrase 'a laser mapping technology' within a pair of commas. Because this phrase is parenthetical, removing it leaves a grammatically complete main clause. Additionally, it correctly avoids placing commas around the restrictive relative clause 'that were previously invisible', keeping the modifier linked to the noun it restricts.

Step-by-Step Solution

1
Identify any parenthetical or nonessential elements in the sentence.
The phrase 'a laser mapping technology' describes LiDAR but is not essential to the core meaning of the sentence.
Identifying nonessential modifiers allows you to apply the appropriate comma rules to set them off from the main clause.
2
Determine the punctuation required for the nonessential appositive.
A pair of commas must enclose 'a laser mapping technology' (one after 'LiDAR' and one after 'technology').
Using a semicolon is incorrect because a semicolon must separate two independent clauses, and omitting one of the commas leaves a single dangling comma.
3
Analyze whether the relative clause starting with 'that' requires commas.
The clause 'that were previously invisible' restricts the meaning of 'structures' and is essential to the sentence, so it must not have commas.
Restrictive clauses are necessary to specify the referent and should never be isolated with commas.

Question 579Question →

Passage:
[1] In the mid-twentieth century, Mayan hieroglyphs were widely believed by scholars to represent only abstract calendar dates and astronomical observations. [2] Tatiana Proskouriakoff revolutionized Mayanist studies by analyzing patterns in the stone monuments, or stelae, at the ancient city of Piedras Negras. [3] She noticed that the dates inscribed on consecutive monuments matched the typical spans of human lifetimes, suggesting the carvings depicted the births, accessions, and deaths of individual rulers. [4] _She argued that these monuments served as records of political events._

The writer wants to revise the underlined portion of sentence [4] to provide the most specific, concrete visual details to support the claim that the carvings depicted the biographical events of rulers' lives. Which choice best accomplishes this goal?

Show answer & explanation

Answer

Her analysis identified specific glyphs associated with royal births, including the 'upended frog' symbol, and accessions, marked by a figure seated on a dais.
The correct answer successfully fulfills the rhetorical goal by providing clear, concrete visual details of the glyphs, namely the 'upended frog' symbol for births and a 'figure seated on a dais' for accessions, which directly support the claim that the carvings depicted the biographical lives of rulers.

Step-by-Step Solution

1
Identify the rhetorical goal specified in the prompt: to provide specific, concrete visual details supporting the claim that the carvings depicted the biographical events of rulers' lives.
The target details must describe specific visual symbols or markers related to biographical milestones like births or accessions.
This sets up the criteria to filter out choices that are too general or lack visual descriptions.

Evaluate the choices for grammatical correctness.
The option beginning with 'Analyzing these monuments' contains a dangling modifier. The option containing 'complex historical documents; which...' creates a fragment due to the incorrect use of a semicolon. These two options are eliminated.
ACT English requires all answers to be grammatically correct.
3
Compare the remaining grammatically correct options for specificity and relevance to the rhetorical goal.
The option focusing on the 'Piedras Negras monuments' is factually true and grammatically correct, but it offers only general information. The option detailing the 'upended frog' symbol and a 'figure seated on a dais' provides specific, concrete visual evidence directly linked to biographical events.
This step determines which grammatically correct choice best fulfills the specific writing goal.

To prepare for the winter storm, the two family's houses were reinforced with extra insulation and storm shutters. Which of the following options represents the correct punctuation for the underlined portion?

Show answer & explanation

Answer: families'

Answer

The correct answer is the plural possessive form 'families'' because the sentence refers to two families who own houses.
The plural possessive form 'families'' is correct because the word 'two' establishes that multiple families are being referenced, and they own the houses being described. For plural nouns ending in 's', possession is shown by adding only an apostrophe at the end of the word.

Step-by-Step Solution

1
Identify if the underlined noun is singular or plural based on the context.
The modifier 'two' indicates that the noun refers to more than one family, so the plural form 'families' is required.
To determine the correct base noun form before applying possessive punctuation.
2
Determine whether possession is required in the sentence.
The noun modifies 'houses', showing that the houses belong to the families, so a possessive form is necessary.
To decide if an apostrophe is needed to show ownership.
3
Apply the correct apostrophe rule for regular plural nouns ending in 's'.
For a plural noun ending in 's', the apostrophe is placed after the 's', resulting in 'families''.
To correctly format the plural possessive noun.
