Choice C is the best answer. The convention being tested is parallel structure. The past tense verb 'exchanged' maintains parallelism with 'exchanged' earlier in the sentence, creating a coordinate structure with 'not only...but also.'
Why the others are wrong
AThis choice incorrectly uses the base form 'exchange' when the past tense 'exchanged' is needed to maintain parallel structure and match the historical context.
BThis choice incorrectly uses the present tense 'exchanges' when the past tense 'exchanged' is required for parallel structure and to match the historical timeframe.
DThis choice incorrectly uses the present participle 'exchanging' when the past tense finite verb 'exchanged' is needed to maintain parallelism with the earlier verb.

A main clause requires a finite verb to perform the action of the subject, and this choice supplies the finite past tense verb 'attracted,' which agrees with the singular subject 'trip' and matches the past tense context established by 'embarked.'
Why the others are wrong
AThis choice incorrectly uses the present tense plural verb form 'attract,' which does not agree with the singular subject 'trip.'
CThis choice incorrectly uses the future tense 'will attract,' which does not match the past tense context of the narrative established by 'embarked.'
DThis choice incorrectly uses the nonfinite present participle 'attracting,' which cannot serve as the main verb of the clause.

Which choice completes the text so that it conforms to the conventions of Standard English?
Show the answer and explanation

Choice A is the best answer. The convention being tested is pronoun-antecedent agreement and finite verb forms. The plural pronoun 'they' correctly refers to the plural antecedent 'millions of these delicate insects,' and the finite present tense verb 'overwinter' correctly performs the action of the subject.
Why the others are wrong
BThis choice incorrectly uses the singular pronoun 'it' to refer to the plural antecedent 'millions of these delicate insects.'
CThis choice uses a nonfinite verb form ('overwintering') when the sentence requires a finite verb to complete the main clause.
DThis choice creates subject-verb disagreement; the singular verb 'overwinters' does not agree with the plural subject 'millions of these delicate insects.'

Which choice completes the text so that it conforms to the conventions of Standard English?
Show the answer and explanation
Why C is right

Why the others are wrong
AThis choice creates subject-verb disagreement; the plural present tense verb 'challenge' does not agree with the singular subject 'His team's discovery.'
BThis choice uses a nonfinite verb form ('challenging') when the sentence requires a finite verb to complete the main clause.
DThis choice uses a nonfinite infinitive form ('to challenge') when the sentence requires a finite verb to complete the main clause.

Which choice completes the text so that it conforms to the conventions of Standard English?
Show the answer and explanation
Why B is right
Choice B is the best answer. The convention being tested is the use of finite and nonfinite verb forms. A main clause requires a finite verb to perform the action of the subject, and the past tense verb 'rediscovered' correctly indicates an action completed in 1812.
Why the others are wrong
AThis choice is incorrect because the bare infinitive form 'rediscover' does not provide the finite verb form needed to complete the main clause.
CThis choice is incorrect because the present participle 'rediscovering' is a nonfinite verb form that cannot function as the main verb of the clause.
DThis choice is incorrect because the pronoun 'him' is unnecessary and creates an awkward construction; the subject 'Johann Ludwig Burckhardt' is already established.

Why D is right
Choice D is the best answer. The convention being tested is the use of possessive nouns and plurals. The singular possessive 'stone's' correctly indicates that there is one stone, and the plural 'inscriptions' correctly indicates that there are multiple inscriptions (three scripts) belonging to that stone.
Why the others are wrong
AThis choice incorrectly uses the possessive form 'inscription's' when the simple plural 'inscriptions' is needed.
BThis choice omits the necessary apostrophe in 'stone's' and incorrectly uses the singular 'inscription' when multiple inscriptions are referenced.
CThis choice incorrectly uses the plural 'stones' when the singular possessive is needed to indicate one stone.

Which choice completes the text so that it conforms to the conventions of Standard English?
Show the answer and explanation
Why A is right
Choice A is the best answer. The convention being tested is the use of plural nouns. The plural noun 'populations' correctly indicates that DDT threatened multiple bird populations, and the simple plural form is appropriate since nothing belongs to the populations.
Why the others are wrong
BThis choice incorrectly uses the singular 'population' when the plural 'populations' is needed to refer to multiple groups of birds affected by DDT.
CThis choice incorrectly uses the plural possessive form when the simple plural 'populations' is needed, as nothing in the sentence belongs to the populations.
DThis choice incorrectly uses the singular possessive form when the plural form 'populations' is required to indicate multiple bird groups.

Why the others are wrong
AThis choice uses a nonfinite verb form ('establishing') when the sentence requires a finite verb to complete the main clause.
BThis choice incorrectly uses the present tense verb 'establishes' when the context requires the past tense to match the time frame of 1925.
DThis choice creates subject-verb disagreement; the plural verb 'have established' does not agree with the singular subject 'The study.'

Which choice completes the text so that it conforms to the conventions of Standard English?
Show the answer and explanation
Why A is right
Choice A is the best answer. The convention being tested is modifier placement and sentence structure. The phrase 'produced by photosynthesis' correctly modifies 'glucose' without introducing unnecessary punctuation or pronouns that would create a run-on or fragment.
Why the others are wrong
BThis choice incorrectly adds a comma after 'photosynthesis,' which creates an inappropriate pause and suggests the beginning of a new independent clause that does not follow.
CThis choice incorrectly adds the pronoun 'it' without proper punctuation, creating a run-on sentence.
DThis choice incorrectly adds both a comma and the pronoun 'it,' creating faulty sentence structure with an unnecessary subject for the verb 'serves.'

Show the answer and explanation
Why D is right
Choice D is the best answer. The convention being tested is the use of finite verb forms and subject-verb agreement. The finite past tense verb 'earned' correctly performs the action of the singular subject 'Her 1987 masterpiece Beloved' and matches the past time frame of 1987.
Why the others are wrong
AThis choice creates subject-verb disagreement; the plural present tense verb 'earn' does not agree with the singular subject 'Her 1987 masterpiece Beloved.'
BThis choice uses a nonfinite verb form ('earning') when the sentence requires a finite verb to complete the main clause.
CThis choice uses a nonfinite infinitive form ('to earn') when the sentence requires a finite verb to complete the main clause.

Which choice completes the text so that it conforms to the conventions of Standard English?
Show the answer and explanation
Why A is right
Choice A is the best answer. The convention being tested is the use of plural nouns. The simple plural noun 'dolphins' correctly indicates multiple dolphins that can recognize the whistles, with no possession involved.
Why the others are wrong
BThis choice is incorrect because the possessive form 'dolphins'' suggests ownership, but the context requires a simple plural noun as the subject of the verb 'can recognize.'
CThis choice is incorrect because the singular 'dolphin' does not agree with the plural verb 'can recognize' and contradicts the idea of multiple dolphins recognizing whistles.
DThis choice is incorrect because the participial phrase 'having recognized dolphins' creates an illogical construction that obscures the intended meaning of the sentence.
Question 12Easy

Which choice completes the text so that it conforms to the conventions of Standard English?
Show the answer and explanation
Why C is right

The singular subject 'work' requires the singular verb 'has transformed,' and the present perfect tense appropriately indicates an action that began in the past and continues to have effects in the present.
Why the others are wrong
AThis choice incorrectly uses the plural verb form 'have transformed' with the singular subject 'work.'
BThis choice incorrectly uses the nonfinite participle 'transforming,' which cannot serve as the main verb of the clause.
DThis choice incorrectly uses the infinitive form 'to transform,' which cannot serve as the main verb of the clause.

DThis choice uses a nonfinite infinitive form ('to have challenged') when the sentence requires a finite verb to complete the main clause.
Question 14Easy

Which choice completes the text so that it conforms to the conventions of Standard English?
Show the answer and explanation
Why A is right
Choice A is the best answer. The convention being tested is punctuation with modifying phrases. The comma after 'centuries' is necessary to set off the participial phrase 'constructed over many centuries' from the main clause that follows.
Why the others are wrong
BThis choice is incorrect because it lacks the comma needed to separate the modifying phrase from the main clause, creating a run-on construction.
CThis choice is incorrect because the singular 'century' does not logically fit with the plural demonstrative 'These' and the extensive timeframe implied by the context.
DThis choice is incorrect because 'being' creates an awkward and unnecessarily wordy construction that disrupts the flow of the sentence.

Which choice completes the text so that it conforms to the conventions of Standard English?
Show the answer and explanation
Why C is right
Choice C is the best answer. The convention being tested is subject-verb agreement. The singular subject 'presence' requires the singular verb 'has,' and the present perfect tense is appropriate for describing an action that began in the past and continues to have effects.
Why the others are wrong
AChoice A is incorrect because the plural verb 'have' does not agree with the singular subject 'presence.'
BChoice B is incorrect because the nonfinite verb form 'having' cannot function as the main verb of the clause.
DChoice D is incorrect because the past perfect tense 'had' suggests an action completed before another past action, but the sentence describes ongoing effects.
Question 16Easy

Her discovery of these mobile genetic elements, later called transposons, ______ initially met with skepticism by the scientific community but eventually earned her the Nobel Prize in Physiology or Medicine in 1983.
Which choice completes the text so that it conforms to the conventions of Standard English?
Show the answer and explanation
Why B is right
Choice B is the best answer. The convention being tested is subject-verb agreement. The singular subject 'Her discovery' requires the singular past tense verb 'was' despite the intervening prepositional phrase 'of these mobile genetic elements.'
Why the others are wrong
AThis choice is incorrect because the plural verb 'were' does not agree with the singular subject 'Her discovery.'
CThis choice is incorrect because the participle 'being' is a nonfinite verb form that cannot function as the main verb needed to complete the clause.
DThis choice is incorrect because the pronoun 'it' is unnecessary and creates redundancy; the subject 'Her discovery' is already clearly established in the sentence.

Which choice completes the text so that it conforms to the conventions of Standard English?
Show the answer and explanation
Why C is right
Choice C is the best answer. The convention being tested is verb tense. The past tense 'expanded' is correct because it matches the past tense established by 'composed' and refers to historical actions that Ellington completed during his career.
Why the others are wrong
AChoice A is incorrect because the present tense 'expands' is inconsistent with the past tense context established in the passage.
BChoice B is incorrect because the nonfinite verb form 'expanding' cannot serve as the main verb of the clause.
DChoice D is incorrect because the present tense 'expand' is inconsistent with the past tense context and also fails to agree with the singular subject 'achievement' if construed that way.

Which choice completes the text so that it conforms to the conventions of Standard English?
Show the answer and explanation
Why A is right
Choice A is the best answer. The convention being tested is punctuation with appositives. The comma after 'poets' correctly separates the appositive phrase 'one of the movement's most celebrated poets' from the main clause that follows.
Why the others are wrong
BThis choice omits the necessary comma, creating a run-on sentence that fails to properly separate the appositive from the independent clause.
CThis choice incorrectly uses the possessive form 'poet's' when the plural 'poets' is required, and the singular form also creates subject-verb disagreement.
DThis choice incorrectly uses the possessive singular form when the context requires the plural form 'poets' to indicate Hughes was one among many.

Scientists warn that if current rates of forest loss continue, the rainforest ______ ability to regulate global climate patterns could be permanently damaged.
Which choice completes the text so that it conforms to the conventions of Standard English?
Show the answer and explanation
Why C is right
Choice C is the best answer. The convention being tested is the use of possessive nouns. The singular possessive 'rainforest's' correctly indicates that the ability belongs to the single rainforest being discussed.
Why the others are wrong
AThis choice is incorrect because the plural possessive 'rainforests'' suggests multiple rainforests, but the passage consistently refers to the Amazon rainforest as a single entity.
BThis choice is incorrect because the simple plural 'rainforests' does not show the required possessive relationship between the rainforest and its ability.
DThis choice is incorrect because the participial phrase 'having been the rainforest's' creates an unnecessarily complex and illogical construction.
Question 20Easy
Volcanic eruptions can have significant climate impacts. The 1815 eruption of Mount Tambora in Indonesia released massive amounts of ash and sulfur dioxide into the atmosphere, which ______ global temperatures and led to crop failures across Europe and North America.
Which choice completes the text so that it conforms to the conventions of Standard English?
Show the answer and explanation
Why C is right
Choice C is the best answer. The convention being tested is verb tense and parallelism. The past tense 'lowered' correctly matches the past tense context of the 1815 eruption and parallels the structure of 'led' that follows.
Why the others are wrong
AThis choice incorrectly uses the base form 'lower' when a finite past tense verb is needed to match the historical context and parallel structure with 'led.'
BThis choice incorrectly uses the present tense 'lowers' when the past tense is needed to match the 1815 timeframe and maintain parallel structure.
DThis choice incorrectly uses the present participle 'lowering,' creating a nonfinite verb form that breaks the parallel structure with the finite verb 'led.'
