Question 121Question

During the regional baking championship, chef Leo and his apprentice Marcus prepared a complex chocolate soufflé. Leo carefully measured the imported cocoa powder while Marcus whipped the egg whites to stiff peaks. After placing the dessert into the preheated oven, he set a digital timer for exactly eighteen minutes.

Which choice is the best replacement for the underlined pronoun to make the sentence clear?

Show answer & explanation

Answer: Leo

Answer

Leo
Replacing the pronoun with the specific proper noun 'Leo' is the correct answer because it directly resolves the pronoun ambiguity. Since the passage introduces two male individuals, the pronoun 'he' could refer to either of them, creating a clarity issue that is solved by naming the specific person who set the timer.

Step-by-Step Solution

1
Identify the underlined pronoun and its potential antecedents in the passage.
The underlined pronoun is 'he', and the preceding sentence mentions two singular male individuals: 'chef Leo' and 'his apprentice Marcus'.
To check for pronoun clarity, you must ensure that every pronoun has exactly one clear and unambiguous noun antecedent.
2
Evaluate the choices to find the one that removes any ambiguity while maintaining grammatical correctness.
Replacing 'he' with the name 'Leo' clarifies who performed the action without introducing any grammatical errors.
Using the specific noun is the most effective way to resolve an ambiguous pronoun reference.

Question 122Question

Under the guidance of the lead conductor, the complex orchestration of woodwinds, brass, and percussion require meticulous rehearsal to execute perfectly. The musicians must practice for hours each day to synchronize their timing before the opening night of the symphony.

Which choice best completes the sentence with correct subject-verb agreement?

Show answer & explanation

Answer: requires

Answer

The correct option is the singular verb 'requires', which properly agrees with the singular subject 'orchestration'.
The singular verb 'requires' is correct because the subject of the clause is the singular noun 'orchestration'. The intervening prepositional phrase 'of woodwinds, brass, and percussion' contains plural nouns, but these do not change the number of the subject. Therefore, a singular verb is required to maintain subject-verb agreement.

Step-by-Step Solution

1
Identify the subject of the clause containing the underlined verb.
The subject is the singular noun 'orchestration'.
The verb must agree in number (singular or plural) with its grammatical subject.
2
Identify and disregard any intervening phrases between the subject and the verb.
The prepositional phrase 'of woodwinds, brass, and percussion' separates the subject from the verb but does not change the subject's singular number.
Nouns inside prepositional phrases or other modifier phrases do not act as the subject of the verb.
3
Select the verb form that is both singular and in the appropriate tense for the context.
The simple present singular form 'requires' is correct.
The surrounding context uses the present tense, so the verb must match both the singular number of the subject and the present tense of the passage.

Key Concept

Subject-verb agreement requires a verb to match the number of its subject, even when separated by intervening plural prepositional phrases.

Question 123Question

Which choice is the correct replacement for the underlined portion in the sentence below?

After weeks of intense negotiations, the delegation of international diplomats finally presented their draft of the treaty to the General Assembly.

Show answer & explanation

Answer: its

Answer

its
The correct option is the singular possessive pronoun 'its'. The antecedent is 'delegation', which is a singular collective noun. Although the plural noun 'diplomats' appears in the intervening prepositional phrase 'of international diplomats', the head of the subject noun phrase is 'delegation', which is singular. Thus, the singular possessive pronoun 'its' is required to agree with it.

Step-by-Step Solution

1
Identify the antecedent of the underlined pronoun in the sentence.
The pronoun refers to the 'delegation' of international diplomats.
To ensure correct pronoun-antecedent agreement, we must first determine the noun or noun phrase that the pronoun is replacing or referring to.
2
Determine the number (singular or plural) of the antecedent.
The noun 'delegation' is a collective noun acting as a single unit, which makes it singular. The plural noun 'diplomats' is inside the prepositional phrase 'of international diplomats' and does not affect the number of the head noun 'delegation'.
Intervening prepositional phrases often contain nouns of a different number, so we must isolate the true head noun to determine agreement.
3
Select the correct pronoun that is singular and possessive to fit the context.
The singular possessive pronoun is 'its'. We must avoid contractions like 'it's' and plural forms like 'their' or 'they're'.
The sentence requires a possessive pronoun to modify 'draft'. Choosing 'its' ensures agreement in number and avoids confusion with contractions.

Question 124Question

Read the passage below and answer the question that follows.

While observing the two chimpanzees in the enclosure, the biologist noticed that the younger one was mimicking the feeding habits of the older one. The research team had spent weeks documenting these social interactions in detail. However, after a few minutes, he began to search for a new nesting site near the perimeter wall. This sudden change in activity was immediately noted in the logbook.

Which option best replaces the bolded word to ensure that the sentence is clear and grammatically correct?

Show answer & explanation

Answer: the younger chimpanzee

Answer

the younger chimpanzee
The correct option replaces the ambiguous pronoun with the specific noun phrase 'the younger chimpanzee', which clearly identifies the subject of the action and eliminates any confusion about who began searching for a nesting site.

Step-by-Step Solution

1
Identify the pronoun being tested and its potential antecedents in the passage.
The pronoun is 'he', and the preceding context contains multiple singular male nouns: the biologist, the younger chimpanzee (referred to as 'the younger one'), and the older chimpanzee ('the older one').
Identifying potential antecedents helps determine if the pronoun's reference is clear or ambiguous.
2
Evaluate the options to find the one that removes ambiguity while maintaining correct grammar and tone.
Replacing 'he' with the specific noun 'the younger chimpanzee' clearly identifies the subject, whereas the other options either maintain the ambiguity, introduce a grammar error, or violate the academic tone.
Replacing an ambiguous pronoun with a specific noun is the correct way to resolve reference errors on the ACT.

Question 125Question

Which pronoun correctly completes the sentence below to ensure proper pronoun-antecedent agreement?

Fill in the blanks below

Although the scientific coalition of climate researchers published a unified statement, each of the individual member organizations retained right to release independent data.
Show answer & explanation

Answer

its
The singular indefinite pronoun 'each' acts as the subject and antecedent of the clause. Therefore, the singular possessive pronoun 'its' is required to maintain correct agreement. The plural noun 'organizations' is part of an intervening prepositional phrase and does not affect the number of the pronoun.

Step-by-Step Solution

1
Identify the antecedent of the pronoun to be filled in the blank.
The antecedent is the singular indefinite pronoun 'each'.
In the clause 'each of the individual member organizations retained...', the grammatical subject and antecedent is 'each', not the plural noun 'organizations' which is the object of the preposition.
2
Select a pronoun that matches the singular number and neutral gender of the antecedent.
The singular possessive pronoun 'its' is correct.
Because 'each' is a singular indefinite pronoun referring to neutral organizations, the possessive pronoun must be 'its'.

Question 126Question

After months of preparation, the lead curator invited the museum board members and he to join the VIP tour, advising that if one wishes to fully appreciate the exhibit and it's history, you should read the catalog beforehand.

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

Show answer & explanation

Answer: him to join the VIP tour, advising that if you wish to fully appreciate the exhibit and its history, you

Answer

The option that begins with 'him to join the VIP tour' and uses 'its history' is the correct choice because it resolves the pronoun case error, the shift in pronoun person, and the homophone error.
The correct option fixes all three grammatical errors in the underlined portion. First, the verb 'invited' requires an objective case pronoun ('him' instead of 'he') because it serves as a direct object. Second, the pronoun person must remain consistent; shifting from 'one' to 'you' is incorrect, so using 'you' consistently resolves the shift. Third, the possessive pronoun 'its' is needed to show ownership of 'history', whereas 'it's' is a contraction meaning 'it is'.

Step-by-Step Solution

1
Analyze the pronoun case in the compound object.
The pronoun follows the transitive verb 'invited' as part of the compound direct object 'the museum board members and [he/him]'. Therefore, the objective case pronoun 'him' must be used.
Objects of verbs must be in the objective case.
2
Check for pronoun person consistency.
The original phrasing shifts from the third-person 'one' ('if one wishes') to the second-person 'you' ('you should'). Using 'you' in both instances ('if you wish ... you') maintains person consistency.
Shifting pronoun person within a sentence creates grammatical inconsistency.
3
Check the spelling of the possessive pronoun.
The sentence refers to the history of the exhibit, requiring the possessive pronoun 'its'. The contraction 'it's' (meaning 'it is') is incorrect.
Possessive pronouns do not use apostrophes, whereas 'it's' is a contraction.

Question 127Question

The following passage is an excerpt from an essay on American history.

During the late nineteenth century, civil rights activists Ida B. Wells and Frances Ellen Watkins Harper worked tirelessly to combat racial injustice. While Harper focused primarily on suffrage and education through her poetry and essays, Wells gained prominence for her investigative journalism exposing the horrors of lynching. Despite their distinct approaches, this frequently brought them into the same reform circles, where they collaborated on founding the National Association of Colored Women. Today, their combined efforts are celebrated as foundational to modern intersectional activism.

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

Show answer & explanation

Answer: their shared commitment to justice

Answer

The correct answer is the phrase that specifies their shared commitment to justice, as it replaces the vague pronoun with a clear and grammatically precise noun phrase.
The correct option replaces the vague pronoun with a specific noun phrase. In the original sentence, the pronoun is used without a clear singular noun antecedent, referring instead to the general concept of their activism or work described in the previous sentence. Replacing it with the noun phrase provides a clear, grammatically precise subject for the verb that follows.

Step-by-Step Solution

1
Analyze the underlined pronoun to determine if it has a clear, specific noun antecedent.
The pronoun has no clear singular noun antecedent in the sentence, as it refers vaguely to the overall action or approach of the activists.
A pronoun must refer clearly to a specific, singular noun antecedent rather than an entire clause or idea.
2
Evaluate the choices to find one that resolves the vague pronoun reference.
The option providing a concrete noun phrase successfully establishes a clear subject for the clause.
Replacing a vague pronoun with a specific noun phrase eliminates ambiguity and ensures grammatical clarity.
3
Check the remaining options for grammatical correctness and sentence structure.
The relative pronoun creates a sentence fragment, while the singular personal pronoun remains vague without a clear antecedent.
Options must not introduce new grammatical errors such as sentence fragments or unresolved pronoun references.

Question 128Question

A team of marine biologists is currently monitoring the health of the Great Barrier Reef. The sudden increase in temperature and salinity, along with the rising acidity of the ocean waters, have threatened the survival of these marine habitats. If these trends continue, the consequences will be devastating.

Which of the following options is the correct replacement for the underlined portion?

Show answer & explanation

Answer: has threatened

Answer

has threatened
The singular subject 'increase' requires a singular verb. The present perfect form 'has threatened' maintains grammatical agreement and matches the present-tense context of the surrounding sentences ('is currently monitoring', 'continue').

Step-by-Step Solution

1
Identify the true subject of the verb in the sentence.
The subject is the singular noun 'increase'.
The noun phrase 'in temperature and salinity' is a prepositional phrase, and the phrase 'along with the rising acidity of the ocean waters' is a parenthetical modifier. Neither of these changes the singular nature of the subject.
2
Determine the correct verb number (singular or plural).
A singular verb is required to agree with 'increase'.
Subject-verb agreement requires a singular subject to pair with a singular verb form.
3
Analyze the tense of the surrounding context to ensure consistency.
The present perfect tense 'has threatened' is correct.
The passage establishes a present time frame ('is currently monitoring', 'continue', 'will be'). The present perfect tense correctly links the past/ongoing action to the present situation without an unnecessary tense shift.

Question 129Question

During the late nineteenth century, physicists debated the nature of light. Of the two primary theories proposed to explain its behavior, the wave theory was eventually favored by the scientific community because it accounted for diffraction patterns more clearer than the particle theory.

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

Show answer & explanation

Answer: more clearly

Answer

more clearly
The correct option is 'more clearly' because it uses the adverb form 'clearly' to modify the verb phrase 'accounted for,' and it uses the comparative modifier 'more' which is appropriate for comparing exactly two theories (the wave theory and the particle theory).

Step-by-Step Solution

1
Determine the part of speech modified by the underlined portion.
The underlined phrase describes how the wave theory 'accounted for' diffraction patterns. Since it modifies a verb phrase, an adverb is required rather than an adjective.
Adverbs modify verbs, adjectives, or other adverbs, while adjectives modify nouns.
2
Determine the number of items being compared to choose between comparative and superlative forms.
The passage compares exactly 'two primary theories' (the wave theory and the particle theory). Therefore, the comparative form ('more') is required instead of the superlative form ('most').
Comparative modifiers compare two things, while superlative modifiers are used for three or more things.
3
Identify and eliminate any grammatical errors such as double comparatives or incorrect adjective usage.
The option 'more clearly' satisfies all criteria, as it uses the comparative adverb 'more' and the adverb 'clearly' without creating a double comparative error.
Double comparatives like 'more clearer' are grammatically incorrect, as are adjectives used as adverbs.

Question 130Question

In the late 1960s, computer scientists Grace Hopper and Jean Sammet collaborated on the development of new programming languages. While Hopper championed the use of COBOL, Sammet focused on FORMAC, which was designed for symbolic mathematics. Because of her dedication to making programming accessible to business professionals, the industry saw rapid growth in commercial applications. Today, both women are remembered as pioneers of modern computing.

Which of the following options best replaces the underlined word to ensure grammatical clarity and precision?

Show answer & explanation

Answer: Hopper's

Answer

The correct answer is the option that replaces the pronoun with the specific noun 'Hopper's' to resolve the ambiguity.
The correct option is 'Hopper's'. The pronoun 'her' in the original sentence is ambiguous because it has two potential antecedents in the preceding sentence: Grace Hopper and Jean Sammet. Replacing the pronoun with the specific possessive noun 'Hopper's' clarifies that Grace Hopper is the scientist being described, which matches the context of COBOL's development for business applications.

Step-by-Step Solution

1
Identify the underlined pronoun and its potential antecedents in the passage.
The pronoun is 'her', and the potential antecedents are 'Grace Hopper' and 'Jean Sammet'.
Since both are singular female nouns, the pronoun 'her' could grammatically refer to either person, creating ambiguity.
2
Analyze the context of the sentence to determine which scientist's work is being described.
The sentence mentions 'dedication to making programming accessible to business professionals' leading to 'growth in commercial applications'. Hopper championed COBOL (business), while Sammet focused on FORMAC (symbolic mathematics).
This context indicates that the sentence is referring to Hopper's contributions, not Sammet's.
3
Select the option that replaces the ambiguous pronoun with the clear noun identifier.
Choosing 'Hopper's' resolves the ambiguity and maintains factual accuracy in the passage.
Replacing the pronoun with the specific proper noun ensures the reader immediately knows who is being referenced.

Question 131Question

In 1918, during the final months of World War I, German physicist Max Planck received the Nobel Prize in Physics for his discovery of energy quanta. His colleague Albert Einstein had nominated Planck years earlier, citing his pioneering work on blackbody radiation. Because [he] had long been recognized as a leader in the scientific community, the announcement was met with widespread celebration.

Which choice best replaces the bracketed pronoun to ensure the sentence is clear and grammatically correct?

Show answer & explanation

Answer: Planck

Answer

Planck
Replacing the pronoun with the specific noun 'Planck' is correct because it resolves the ambiguity created by having two male subjects (Max Planck and Albert Einstein) in the preceding sentences, making it clear who was recognized as a leader.

Step-by-Step Solution

1
Identify the underlined pronoun and its potential antecedents in the preceding sentences.
The pronoun is 'he'. The potential antecedents are 'Max Planck' and 'Albert Einstein'.
Determining if a pronoun has multiple possible referents is the first step in assessing pronoun clarity.
2
Evaluate whether the pronoun 'he' clearly points to a single antecedent.
Because both Planck and Einstein are singular male nouns mentioned in the context, 'he' is ambiguous.
Ambiguous pronoun reference is a grammatical error on the ACT; the sentence must clarify which person is being discussed.
3
Select the option that replaces the pronoun with a specific noun to resolve the ambiguity.
Replacing 'he' with 'Planck' makes the sentence clear and precise.
Using the specific noun is the standard way to correct an ambiguous pronoun reference.

Of the two routes to the mountain peak, the northern path is the (safe) option.
Show answer & explanation

Answer

safer
The sentence establishes a comparison between exactly two items ('the two routes'). When comparing two items, the comparative form of the adjective is required. For the one-syllable adjective 'safe', the comparative form is 'safer'.

Step-by-Step Solution

1
Identify the number of items being compared.
Two items (the two routes) are being compared.
This determines whether to use the comparative or superlative form.
2
Determine the correct grammatical form based on the number of items.
The comparative form is required because exactly two items are compared.
Comparative adjectives are used for comparing two items, whereas superlative adjectives are used for three or more.
3
Apply the rule for forming the comparative of the adjective 'safe'.
The comparative form is 'safer'.
One-syllable adjectives form their comparative by adding the suffix '-er'.

Question 133Question

In the sentence 'The environmental biologist documented the growth of the new plant species regular, recording measurements at the same time each morning,' the underlined modifier is used correctly.

Show answer & explanation

Answer: False

Answer

False
The statement is false because the underlined modifier 'regular' is an adjective that is incorrectly used to modify the verb 'documented.' To modify a verb, the adverb form 'regularly' is required.

Step-by-Step Solution

1
Determine which word the underlined modifier is describing.
The word 'regular' describes the verb 'documented.'
To choose the correct modifier form, you must first identify the part of speech of the word being modified.
2
Identify the grammatical rule for modifying a verb.
Verbs must be modified by adverbs, not adjectives.
This determines whether the modifier needs to be an adjective or an adverb.
3
Evaluate the form of the underlined word.
The word 'regular' is an adjective, and its adverb form is 'regularly.' Since it modifies the verb 'documented,' the adjective form 'regular' is incorrect.
This determines the truth value of the statement in the stem.

Question 134Question

Read the following passage about textile conservation:

The delicate restoration of medieval tapestries, which involves stabilizing microscopic silk fibers and repairing dye degradation, demand decades of experience and specialized training. Conservators must work in climate-controlled rooms to prevent humidity from causing further decay to the historic threads.

Which option is the correct grammatical replacement for the underlined word?

Show answer & explanation

Answer: demands

Answer

The option 'demands' is correct because it uses the singular verb form to agree with the singular subject 'restoration'.
The singular verb 'demands' is correct because it agrees with the singular subject 'restoration'. The intervening prepositional phrase 'of medieval tapestries' and relative clause 'which involves...' do not change the number of the subject. The present tense maintains consistency with the next sentence.

Step-by-Step Solution

1
Identify the true subject of the sentence containing the underlined verb.
The subject is 'restoration', which is singular.
The plural nouns 'tapestries', 'fibers', and 'degradation' are part of intervening prepositional phrases or relative clauses and do not affect the subject's grammatical number.
2
Determine the correct verb form and tense based on the subject and the surrounding context.
The verb must be singular ('demands') and in the present tense to match the surrounding sentence ('Conservators must work...').
Subject-verb agreement requires a singular verb for a singular subject, and verb tense consistency requires keeping the sentence in the present tense.

Question 135Question

A colony of leafcutter ants can carry leaves many times their own body weight, demonstrating a remarkable feat of collective strength.

Which choice is the correct replacement for the underlined portion?

Show answer & explanation

Answer: its

Answer

The singular possessive pronoun 'its' correctly agrees in number with the singular collective noun antecedent 'colony'.
The singular possessive pronoun 'its' correctly matches the singular collective noun antecedent 'colony'. The intervening prepositional phrase 'of leafcutter ants' contains a plural noun but does not change the singular nature of the main antecedent.

Step-by-Step Solution

1
Identify the pronoun's antecedent in the sentence.
The antecedent is the collective noun 'colony'.
The pronoun refers to the singular 'colony' as a single unit performing the action, rather than the individual 'ants' in the intervening prepositional phrase 'of leafcutter ants'.
2
Determine the grammatical number of the collective noun antecedent.
The noun 'colony' is singular.
In standard English, collective nouns representing a single group acting in unison are treated as singular.
3
Select the pronoun that is singular, possessive, and spelled correctly.
The correct choice is 'its'.
The word 'its' is the singular possessive pronoun. The spelling 'it's' is a contraction meaning 'it is' or 'it has', which does not fit grammatically.

Question 137Question

The climatologist warned that a major rise in sea levels was eminent if carbon emissions were not drastically reduced over the next decade.

Which choice is the correct replacement for the underlined word?

Show answer & explanation

Answer: imminent

Answer

imminent
The correct answer is the word meaning 'about to happen' or 'impending' because the sentence refers to a future rise in sea levels that is threatened to occur soon if action is not taken. The word 'imminent' is the correct spelling for this meaning.

Step-by-Step Solution

1
Analyze the context of the sentence to determine the intended meaning of the underlined word.
The sentence describes a climatologist warning about a future rise in sea levels that will occur soon if carbon emissions are not reduced. The context requires a word meaning 'about to happen' or 'impending.'
Understanding the context establishes the semantic requirements of the target word.
2
Evaluate the definition of the underlined word to see if it is correct.
The underlined word 'eminent' means famous, respected, or distinguished. This does not make sense when describing a rise in sea levels, meaning a change is necessary.
This step determines whether the original phrasing is grammatically and semantically correct.
3
Compare the definitions of the alternatives to find the word that matches the required meaning.
The word 'imminent' directly translates to 'about to happen' or 'impending,' which fits the context. The other choices, 'immanent' (meaning inherent) and 'prominent' (meaning conspicuous or important), do not convey this temporal relationship.
This identifies the correct homophone based on precise definitions.

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.

Question 140Question

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.
