Read the passage below and select the choice that best replaces the underlined portion to eliminate redundancy.

"The astronaut looked out the window and saw the Earth, which was a round sphere floating in the dark void of space."

Which of the following options best eliminates the redundant phrasing while maintaining correct grammar?

Cevabı ve açıklamayı göster

Cevap: a sphere

Cevap

a sphere
The correct choice is the most concise option because a sphere is already a round object, making the modifier 'round' redundant. The phrasing 'a sphere' functions cleanly as an appositive modifying 'Earth' without introducing any grammatical errors.

Adım Adım Çözüm

1
Identify the redundancy in the underlined phrase.
The phrase 'round sphere' is redundant because a sphere is, by definition, a round three-dimensional shape.
Eliminating redundant words is necessary to make the sentence concise and direct.
2
Evaluate the remaining options for grammatical correctness and conciseness.
The option containing just 'a sphere' is the most concise and forms a grammatically correct appositive phrase. The options that introduce a comma splice or a dependent clause fragment are grammatically incorrect.
ACT English questions require the correct choice to be both grammatically correct and free of redundancy.

Every year, the migration of monarch butterflies attracts thousands of tourists who travel annually to witness the event.

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

Cevabı ve açıklamayı göster

Cevap: attracts thousands of tourists

Cevap

attracts thousands of tourists
The correct answer is the option that deletes 'who travel annually' and only keeps 'attracts thousands of tourists'. This choice is the most concise because the sentence already begins with the phrase 'Every year,' which makes 'annually' redundant. It is also grammatically correct and preserves the author's intended meaning.

Adım Adım Çözüm

1
Identify any redundant or repetitive phrasing in the sentence.
The sentence begins with the phrase 'Every year,' which means that the entire sentence is contextually set to occur on a yearly basis. The underlined portion contains 'who travel annually,' where 'annually' means the same thing as 'every year,' resulting in redundant repetition.
To maintain a clear and concise writing style, synonyms that repeat information already established in the sentence must be eliminated.
2
Evaluate the choices for both conciseness and grammatical correctness.
The option that simply states 'attracts thousands of tourists' removes the redundant reference to yearly travel without changing the sentence's meaning. The other options either keep the redundant word 'annually' or introduce structural grammatical errors such as a sentence fragment or a comma splice.
The correct answer on the ACT English section must be the most concise option that preserves the sentence's meaning and remains grammatically correct.

Cevabı ve açıklamayı göster

Cevap: blooming

Cevap

The correct answer is 'blooming', as it is the most concise choice that avoids redundancy and maintains grammatical correctness.
The option containing only 'blooming' is correct because it is the most concise choice and avoids redundant language while keeping the sentence grammatically sound.

Adım Adım Çözüm

1
Identify repetitive or redundant words in the original sentence.
The words 'currently' and 'at this present time' express the exact same concept of happening in the present moment.
Redundant synonyms must be removed to ensure clear and concise writing.
2
Evaluate the remaining options for both conciseness and grammatical correctness.
The single word 'blooming' eliminates the repetition while fitting the grammatical structure of the sentence. The other options either maintain the redundancy, introduce a comma splice, or create a sentence fragment.
The correct choice must improve conciseness without introducing new grammatical errors.

Although the scientists wanted to present their findings at the annual conference, they had to postpone the scheduled presentation until a later date due to incomplete data.

Which choice best replaces the underlined portion of the sentence?

Cevabı ve açıklamayı göster

Cevap: postpone the presentation

Cevap

postpone the presentation
The correct answer is the option that removes both the redundant phrase 'until a later date' (since 'postpone' already implies a delay to a later time) and the wordy adjective 'scheduled,' resulting in a grammatically correct and concise sentence.

Adım Adım Çözüm

1
Identify the redundancy in the underlined phrase.
The word 'postpone' already indicates that the action is rescheduled for a future time, which makes the phrase 'until a later date' repetitive.
Redundancy is tested on the ACT by checking if the same idea is repeated unnecessarily using different words.
2
Evaluate the choices for both conciseness and grammatical correctness.
The option that simply states 'postpone the presentation' is the most concise choice and avoids grammatical errors such as comma splices or fragment constructions.
The correct answer must improve clarity and economy of language while adhering to rules of standard written English.

During the excavation, the team uncovered a collection of clay tablets. Currently, these ancient artifacts are now stored in the university archives.

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

Cevabı ve açıklamayı göster

Cevap: These ancient artifacts are now stored

Cevap

The option that reads 'These ancient artifacts are now stored' is the correct answer.
The correct choice is the option that states 'These ancient artifacts are now stored.' This version successfully removes the redundant word 'Currently' while preserving a complete, grammatically sound sentence.

Adım Adım Çözüm

1
Identify any redundant phrasing in the underlined segment.
The words 'Currently' and 'now' both indicate the present time. Using both in the same sentence is redundant.
ACT style guides require eliminating unnecessary repetition to maintain concise writing.
2
Evaluate the remaining options for correctness, conciseness, and sentence structure.
The option beginning with 'These ancient artifacts' removes the redundancy. The option beginning with 'Being that' creates a fragment, and the option with two independent clauses creates a comma splice.
The correct choice must not only remove redundancy but also maintain grammatical correctness.

Many archival institutions prioritize the preservation of ancient manuscripts. Because these historic documents are fragile and prone to deterioration, the preservationists handled the folios with extreme care, mindful of the delicate, easily damaged nature of the pages, which could easily break.

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

Cevabı ve açıklamayı göster

Cevap: extreme care, mindful of the pages' delicate nature.

Cevap

The correct choice is the option that states 'extreme care, mindful of the pages' delicate nature.'
The correct option is the most concise choice that successfully eliminates the redundant synonyms ('delicate', 'easily damaged', 'could easily break') while keeping the sentence grammatically sound.

Adım Adım Çözüm

1
Analyze the underlined portion for wordiness and repetitive meaning.
The phrases 'delicate', 'easily damaged', and 'could easily break' all repeat the same basic meaning already established by the word 'fragile' earlier in the sentence.
ACT English requires the elimination of wordy and redundant phrases.
2
Evaluate the choices to find the one that is grammatically correct and most concise.
The option ending in 'delicate nature' is the shortest grammatically correct option. The choice with 'they were mindful' creates a comma splice, and the choice that splits the sentence with a period before 'Mindful' creates a fragment.
The correct choice must resolve both the redundancy and any grammatical errors introduced by the distractors.

Geothermal geysers, such as Yellowstone's Old Faithful, erupt on highly predictable schedules due to the buildup of underground pressure. The geothermal water, which is heated to a high temperature by hot magma beneath the Earth's surface, boils and eventually forces its way upward.

Which of the following options represents the most effective and grammatically correct replacement for the underlined portion?

Cevabı ve açıklamayı göster

Cevap: heated by magma beneath the Earth's surface, boils and

Cevap

heated by magma beneath the Earth's surface, boils and
The correct option is the most concise and grammatically sound choice. The phrase 'heated by magma' communicates the temperature changes clearly without the wordy addition of 'which is heated to a high temperature' and the redundant adjective 'hot' before 'magma,' since magma is inherently hot. It maintains the proper sentence structure by providing the active verbs 'boils' and 'forces' for the subject 'geothermal water.'

Adım Adım Çözüm

1
Identify the redundancy in the underlined portion.
The phrase 'heated to a high temperature' and the adjective 'hot' before 'magma' are redundant, as magma is by definition extremely hot.
ACT English requires the most concise version that preserves the meaning.
2
Eliminate options that fail to correct the redundancy or introduce grammatical errors.
Removing the redundant words leaves 'heated by magma beneath the Earth's surface, boils and'. Check this against options containing punctuation errors or run-ons.
Distractors often try to fix one error while introducing a new grammatical issue.
3
Verify sentence structure with the remaining option.
Inserting the concise option creates a grammatically complete sentence where 'heated by magma beneath the Earth's surface' is a modifying phrase, and 'boils and eventually forces' serves as the compound predicate for 'The geothermal water'.
Ensures the choice maintains complete sentence structure without creating fragments or comma splices.

To transport clean water across long distances, Roman engineers constructed aqueducts, which were vast bridge-like structures that carried water over valleys. Because they relied on gravity alone as the sole force of movement, the conduits had to decline at a precise, consistent slope to prevent stagnation.

Which of the following choices best replaces the underlined portion of the sentence to construct a clear, grammatically correct statement without redundant phrasing?

Cevabı ve açıklamayı göster

Cevap: Because they relied on gravity alone, the

Cevap

Because they relied on gravity alone, the
The correct option, 'Because they relied on gravity alone, the', successfully eliminates the redundant phrase 'as the sole force of movement' from the original sentence. Since 'gravity alone' already conveys that gravity was the only source of propulsion, any additional mention of a 'sole force' is repetitive. This option resolves the redundancy while maintaining grammatical correctness and clear sentence structure.

Adım Adım Çözüm

1
Identify the redundant information in the underlined portion of the sentence.
Recognize that 'gravity alone' and 'sole force of movement' express the exact same concept of a single driving force.
To make the sentence clear and concise, repetitive ideas must be removed.
2
Evaluate the options to find the one that removes this redundancy without introducing grammatical errors.
The choice 'Because they relied on gravity alone, the' removes 'sole force of movement' while maintaining a subordinate clause that logically connects to the main clause.
This establishes a clear cause-and-effect relationship using the subordinator 'Because'.
3
Check the remaining options for grammatical correctness and sentence structure errors.
The choice starting with 'Relying' creates a dependent fragment, while the choice 'They relied on gravity alone, the' results in a comma splice.
Ensuring the selected choice forms a complete, grammatically correct sentence is necessary to satisfy ACT English conventions.

Anahtar Kavram

Redundancy in writing occurs when words or phrases repeat the same information. In standardized tests like the ACT, the most concise grammatically correct option that preserves the sentence's meaning is always preferred.

The paleontologists examined the apex predator's fossilized jaw, it was uniquely adapted for the sole and exclusive purpose of crushing dense bone.

Which of the following choices, if used to replace the underlined portion, most effectively eliminates the redundancy in the sentence?

Cevabı ve açıklamayı göster

Cevap: which was uniquely adapted for

Cevap

The correct choice is the option that uses 'which was uniquely adapted for' to create a subordinate clause and eliminate redundant wording.
The correct option resolves the comma splice by using the relative pronoun 'which' to subordinate the second clause, and it removes the redundant synonyms 'sole' and 'exclusive' to make the sentence concise.

Adım Adım Çözüm

1
Identify any grammatical errors in the original sentence.
The clause starting with 'it was' creates a comma splice when joined to the first independent clause with only a comma.
Before looking at style, ensure the grammar is correct.
2
Identify redundant phrasing in the underlined portion.
The terms 'sole' and 'exclusive' are synonymous, and 'purpose of crushing' is wordier than necessary.
Redundancy weakens style and should be eliminated.
3
Evaluate the options to find one that resolves both the comma splice and the redundancy.
The option using 'which was uniquely adapted for' resolves the comma splice and eliminates the redundancy.
This option is both grammatically correct and concise.

Which choice most effectively eliminates the redundancy in the underlined portion of the sentence while maintaining correct grammar and punctuation?

Cevabı ve açıklamayı göster

Cevap: design; this intentional shape allowed

Cevap

The choice that reads 'design; this intentional shape allowed' is the correct answer.
The correct answer removes the redundancy by eliminating the phrase 'which was planned on purpose,' as 'intentional' already expresses this idea. It also correctly uses a semicolon to separate the two independent clauses.

Adım Adım Çözüm

1
Identify any redundant expressions in the underlined portion.
The words 'intentional' and 'planned on purpose' express the same concept.
Conciseness is a key grammatical standard on the ACT; expressing the same concept twice is redundant.
2
Evaluate the sentence structure of the remaining choices.
The sentence consists of two independent clauses: one about the architects constructing theaters and one about the shape allowing sound waves to travel.
Two independent clauses must be joined by a semicolon or separated by a period, not a comma.
3
Select the option that corrects both issues.
Using a semicolon and removing the redundant phrase makes the sentence both grammatically correct and concise.
This resolves the redundancy while avoiding errors like comma splices or fragments.

Cevabı ve açıklamayı göster

Cevap: ; these cylindrical samples preserve

Cevap

the option that uses a semicolon and eliminates the redundant description of the shape of the ice cores
The correct option is the most effective and concise edit because it removes the redundant phrase 'which are shaped like cylinders' (since 'cylindrical' already conveys this meaning) and correctly uses a semicolon to separate the two independent clauses.

Adım Adım Çözüm

1
Identify the redundancy in the underlined portion.
The words 'cylindrical' and the phrase 'which are shaped like cylinders' are synonymous. One of them must be eliminated to make the sentence concise.
ACT English rewards concise and direct writing that avoids repeating the same meaning.
2
Analyze the grammatical structure of the sentence.
The sentence consists of two independent clauses: 'Climatologists extract ice cores from deep within glaciers' and 'these cylindrical samples preserve tiny bubbles of ancient air'.
Identifying clause boundaries helps determine the correct punctuation needed to connect them.
3
Evaluate the punctuation choices linking the two independent clauses.
A semicolon is required to separate the two independent clauses without a coordinating conjunction. Using a comma creates a comma splice, and adding 'because' after the semicolon creates a fragment.
Standard English conventions require independent clauses to be joined by a semicolon, a period, or a comma with a coordinating conjunction.

In the damp, shaded understory of temperate rainforests, certain species of fungi emit a soft, greenish glow, this glowing illumination, which shines with light, serves to attract nocturnal insects that distribute the fungi's spores.

Which choice is the most concise and grammatically correct replacement for the underlined portion of the sentence?

Cevabı ve açıklamayı göster

Cevap: which serves

Cevap

The correct choice is the option that reads 'which serves', as it creates a grammatically correct relative clause that avoids a comma splice and eliminates all redundant repetition of the word 'glow'.
The correct option is the most concise and grammatically correct choice. By replacing the underlined portion with a relative clause starting with 'which', the sentence correctly joins the dependent clause to the main clause, avoiding a comma splice. Furthermore, it eliminates the redundant phrases 'glowing illumination' and 'shines with light' because the preceding clause already mentions a 'glow'.

Adım Adım Çözüm

1
Analyze the underlined portion for redundancy.
The phrases 'glowing illumination' and 'shines with light' are redundant because the sentence already describes the subject as a 'glow'.
Conciseness is a key rule on the ACT English exam; words or phrases that repeat information already established in the sentence must be removed.
2
Evaluate the sentence structure and punctuation.
The sentence consists of two independent clauses: the first ends with 'glow' and the second begins with the underlined portion. Joining these two clauses with a comma alone creates a comma splice.
To correct a comma splice, the clauses must be separated by a period, a semicolon, a coordinating conjunction, or one clause must be made dependent using a relative pronoun like 'which'.
3
Choose the option that resolves both the redundancy and the grammatical error.
The relative clause 'which serves' removes all redundant wording and correctly joins the clauses, resolving the comma splice.
The correct option must be both grammatically sound and free of unnecessary repetition.

1
Identify redundant words in the underlined portion.
The word 'annually' and the phrase 'once every year' mean the same thing, so one of them must be removed to avoid redundancy.
ACT English style requires sentences to be concise and free of repetitive phrases.
2
Check the remaining options for proper punctuation and grammar.
Using a comma and the relative pronoun 'which' keeps the sentence grammatically complete, whereas using a semicolon creates a fragment, and using 'it' creates a comma splice.

Cevabı ve açıklamayı göster

Cevap: Doctors did not understand

Cevap

Doctors did not understand
The correct answer is 'Doctors did not understand' because it is the most concise choice that conveys the intended meaning without repeating information.
