Question 1
Neighborhood representatives constitute a majority of the housing coalition, while nonprofit organizations and local businesses supply the remaining members. Because each constituent group has different priorities, the coalition requires support from at least one member of every group before adopting a recommendation.
Which explanation best reflects the meanings of "constitute" and "constituent" in this passage?
- The representatives legally establish the coalition, while each group writes its governing constitution.
- The representatives make up most of the coalition, while each named group is a component of it. (correct answer)
- The representatives vote for most coalition members, while each group serves a separate electoral district.
- The representatives temporarily supervise the coalition, while each group independently adopts recommendations.
Explanation: When a question asks you to identify the meaning of related words in context, look at how each word functions in its specific sentence rather than relying on one assumed definition for both.
The word "constitute" comes from the Latin constituere, meaning "to make up or compose." In the passage, neighborhood representatives constitute a majority — meaning they form or make up most of the coalition's membership. The word "constituent" shares this same root: a constituent group is a component part of a larger whole. Answer B correctly captures both meanings — the representatives compose most of the coalition, and each named group (neighborhoods, nonprofits, businesses) is a component that makes up the coalition as a whole.
Answer A misreads "constitute" as meaning "legally establish" and invents a connection to the word "constitution" as a governing document. While these words are etymological cousins, the passage gives no indication of legal founding or written rules. Answer C introduces the idea of voting and electoral districts, which are completely absent from the passage — this confuses "constituent" with its political meaning (a voter represented by an official), which doesn't apply here. Answer D misreads "constitute" as meaning "temporarily supervise" and distorts the coalition's recommendation process, neither of which is supported by the text.
The key strategy here: when two related words appear in a question, don't assume they share one fixed meaning. Check each word's role in its own sentence and let the context guide you — the passage will always contain enough clues to distinguish between meanings.
Question 2
For decades, reviewers interpreted the 1948 directive as prohibiting all commercial activity on the shoreline. Recently discovered correspondence, however, indicates that the directive was intended to limit large industrial projects while permitting small local businesses. This evidence has prompted a reinterpretation of the directive.
How does the prefix in "reinterpretation" modify the meaning of the word family interpret/interpretation?
- It identifies a translation of the directive into a more modern language.
- It proves that every earlier interpretation was deliberately misleading.
- It changes an interpretation into a complete rejection of the directive.
- It indicates that the directive is being interpreted again using new evidence. (correct answer)
Explanation: When a question asks how a prefix modifies a word's meaning, your job is to isolate the prefix, define it precisely, and then trace how it reshapes the base word. Here, the base word is interpret (to explain or make sense of something), and the prefix is re-, which means "again" or "anew." So reinterpretation literally means "the act of interpreting something again."
The passage tells you exactly why a reinterpretation is happening: newly discovered correspondence revealed that the 1948 directive was misunderstood for decades. Because this fresh evidence changed scholars' understanding, the directive is being interpreted again — making D the correct answer. It captures both the prefix's meaning ("again") and the passage's context (new evidence driving a second look).
A is wrong because re- has nothing to do with translation between languages. Translation is a different concept entirely — reinterpretation stays within the same language and concerns meaning, not conversion to another tongue. B is a trap because the passage does not suggest earlier interpretations were deliberate lies or deceptions — just honest mistakes based on incomplete information. The prefix carries no implication of bad intent. C is wrong because reinterpretation does not mean rejection or abandonment of the directive. The prefix re- signals a fresh reading of the same document, not throwing it out.
A useful strategy: when you see a prefix question, mentally strip the prefix away, define the root, then add the prefix back with its precise meaning. Common prefixes like re- (again), pre- (before), and mis- (wrongly) appear frequently on literacy exams and reward this step-by-step approach.
Question 3
The audit reports that overtime expenses rose after two vacancies occurred, but it does not directly state that the vacancies caused the entire increase. Because several departments also changed their scheduling practices, a causal conclusion would require additional evidence.
Which sentence correctly uses the infer/inference word family to describe a careful reader's reasoning about the audit?
- A reader may infer a connection between the vacancies and overtime costs, but that inference should remain tentative given the other explanations. (correct answer)
- A reader can infer that the vacancies are the only cause, because the audit's inference rules out all scheduling changes.
- A reader's inference that overtime costs fell is supported by the direct evidence the audit provides.
- A reader should infer that the audit's findings are invalid, since an inference based on incomplete records cannot be trusted.
Explanation: When a question asks you to evaluate how a word family (like infer/inference) is being used, check two things at once: Is the word used correctly in context, and does the reasoning it describes match what the passage actually supports?
In this passage, the audit notes a correlation — overtime rose after vacancies appeared — but explicitly stops short of claiming causation, pointing out that scheduling changes may also be responsible. A careful reader, then, can draw a cautious connection but shouldn't overcommit to any single explanation. That's exactly what answer A does: it uses infer to describe a tentative conclusion and inference to name that conclusion, while correctly signaling that it should remain uncertain given competing explanations. Both the vocabulary and the reasoning are accurate. A is the correct answer.
Answer B fails on both counts. It misrepresents the passage by claiming the audit "rules out all scheduling changes" — it does the opposite — and it misuses inference to suggest certainty the passage never provides. B turns a careful reading into a reckless one.
Answer C contains a factual error: the passage says overtime costs rose, not fell. Because the inference described flatly contradicts the evidence, C demonstrates exactly the kind of careless reading the question warns against.
Answer D goes too far in the other direction. Incomplete evidence calls for caution, not automatic dismissal. Inferring that findings are invalid is an overreaction, and the reasoning here confuses "uncertain" with "untrustworthy."
Strategy tip: On inference questions, watch for answer choices that replace tentative conclusions with absolute ones — that swap "may suggest" for "proves." The exam frequently tests whether you recognize that good inferences match the strength of the evidence behind them.
Question 4
A three-year grant provided sustained funding for the community health clinic, allowing it to operate without interruption during that period. The directors nevertheless questioned whether the clinic had a sustainable financial model because no replacement revenue had been identified. Their final report therefore focused on long-term sustainability.
Which statement best distinguishes the meanings of the three words from the sustain word family?
- "Sustained" means environmentally responsible, while "sustainable" and "sustainability" refer only to grant length.
- "Sustained" means permanently guaranteed, while "sustainable" describes funding that has already ended.
- "Sustained" describes reduced funding, while "sustainable" and "sustainability" describe uninterrupted expansion.
- "Sustained" describes continued support, while "sustainable" and "sustainability" concern the capacity to continue. (correct answer)
Explanation: When a question asks you to distinguish words from the same word family, your job is to look carefully at how each form functions in context — not just assume they mean the same thing. Words like sustained, sustainable, and sustainability share a root but carry distinct meanings depending on their grammatical role and usage.
In the passage, "sustained funding" describes something that continued over a specific period — the three-year grant kept the clinic running without interruption. That's a descriptive, backward-looking term about what already happened. "Sustainable," however, appears in a forward-looking concern: did the clinic have a model that could continue on its own? "Sustainability" then names that capacity as an abstract concept the report examined. Answer D captures this distinction precisely — "sustained" describes continued support that occurred, while "sustainable" and "sustainability" concern the capacity to keep going in the future.
Answer A is wrong because "sustained" has nothing to do with environmental responsibility here — that's a different, unrelated meaning the word can have in other contexts. Associating it with environmental topics is a classic vocabulary trap. Answer B is wrong because "sustained" does not mean "permanently guaranteed" — the passage actually implies the opposite, since the funding had a defined endpoint. Answer C is wrong because nothing in the passage describes reduced funding or uninterrupted expansion; both of those ideas are invented and contradict the text entirely.
A useful strategy: when you see a word-family question, identify the grammatical form of each word (verb, adjective, noun) and trace how each one is used in the passage. Different forms of the same root often serve different functions and carry subtly different meanings.
Question 5
The research team could not the regional cost index from a single source. Its required combining wage records, housing data, and transportation expenses, then adjusting each category for inflation.
Which pair from the derive word family best completes the passage?
- derivation; derivative
- derivative; derive
- derive; derivation (correct answer)
- derived; derivative
Explanation: When a question asks you to choose the right form of a word for a sentence, you need to identify what grammatical role each blank plays — is it a verb, noun, adjective, or something else? — and then match the correct word form to that role.
In the first sentence, the blank follows "could not," which means you need a base verb (infinitive form). The team "could not do something" — so the blank demands a verb. In the second sentence, "Its required combining..." uses the word as the subject of the sentence, which means you need a noun. Looking at choice C, derive is the base verb form ("could not derive the index") and derivation is the noun form ("Its derivation required..."). Both fit their blanks grammatically and make logical sense in context. C is your answer.
Choice A places derivation (a noun) where a verb is needed and derivative (an adjective/noun meaning something derived from something else) where a process-noun is needed — both slots are wrong. Choice B puts derivative in the verb slot, which doesn't work grammatically at all; you can't say "could not derivative." Choice D uses derived, a past participle/adjective, in the verb slot — while it can function verbally in passive constructions, "could not derived" is grammatically incorrect without "be."
A useful strategy: when you see word-family questions, label each blank's grammatical role before looking at the answer choices. Ask yourself: verb? noun? adjective? Once you know the role, eliminate any choice that puts the wrong form in the wrong slot.
Question 6
Bus ridership varied considerably across the year. The agency attributed some of this variability to school calendars, but it identified severe weather as another important variable when comparing monthly totals.
Based on the relationship among the words "varied," "variability," and "variable," what does the passage mean by calling weather a "variable"?
- Weather is a factor whose changes may help explain changes in ridership. (correct answer)
- Weather is a measurement that remains stable while ridership changes.
- Weather is an irregular result produced by changes in school calendars.
- Weather is a minor exception that should be removed from the totals.
Explanation: When a question asks you to use related word forms to unlock a meaning, you're being tested on word families — groups of words that share a root and shift in meaning as they shift in part of speech. Here, "varied," "variability," and "variable" all come from the Latin root vari-, meaning change or difference. Recognizing that shared root is the key to this question.
"Varied" describes how ridership changed across the year. "Variability" names that quality of changing. "Variable," used as a noun, refers to something that causes or represents change — a factor whose fluctuations influence an outcome. So when the passage calls weather a "variable," it means weather is something that shifts, and those shifts may help explain why ridership shifts. That makes A correct: weather is a factor whose changes may help explain changes in ridership.
B is the opposite of the word's meaning — a variable is defined by its tendency to change, not remain stable. C confuses cause and effect; weather isn't produced by the school calendar, and the passage presents them as two separate explanatory factors. D misreads "variable" as something negative to be excluded, when the passage actually highlights weather as an important explanatory factor, not a minor exception.
A useful strategy: when a question highlights related word forms like this, trace the shared root and ask how the meaning evolves across parts of speech. A noun variable is a factor that varies — it's the source of change, not the result of it. That distinction will serve you across many reading and vocabulary questions.
Question 7
A workplace study found a statistically significant difference in completion times between employees using two software systems. The researchers cautioned, however, that the average difference was only twelve seconds per task and might not justify the expense of replacing the existing system. They distinguished statistical significance from practical significance.
How does the word family significant/significance help clarify the researchers' conclusion about the two software systems?
- The measured difference is unlikely to be due to chance alone, but whether it is large enough to matter in practice remains an open question. (correct answer)
- The measured difference is large enough to require replacing the existing software immediately, because any statistically significant finding demands action.
- The measured difference is practically important because every employee in the study completed tasks faster with the new system.
- The measured difference lacks statistical significance because a twelve-second gap is too small to produce a meaningful result in any study.
Explanation: When you see a question asking how a word or word family "helps clarify" meaning, you're being tested on vocabulary in context — specifically, whether you understand how one word can carry different shades of meaning depending on the phrase it appears in. Here, significant and significance each do different work depending on whether they're paired with statistical or practical.
The researchers used both terms deliberately. Statistical significance means the twelve-second difference is real — unlikely to have occurred by random chance. Practical significance asks a separate question: does that real difference actually matter in the real world? The researchers answered "probably not," because twelve seconds per task likely doesn't justify the cost of replacing an entire software system. Answer A captures this distinction precisely — the difference is genuine but its real-world value is still an open question.
Answer B is a trap that conflates the two types of significance. Statistical significance does not automatically demand action; it only tells you the result is probably not a fluke. Answer C misrepresents the passage entirely — it introduces a claim about every employee completing tasks faster, which the passage never states, and it wrongly treats the finding as practically important when the researchers explicitly cautioned it might not be. Answer D gets things exactly backwards: the study did find statistical significance. A small gap in seconds doesn't disqualify a finding from being statistically significant.
A useful strategy: when a passage uses the same word in two different phrases, treat each phrase as its own concept. Writers and test-makers do this intentionally, and the question will almost always hinge on the contrast between them.
Question 8
Before reopening the factory, engineers completed an assessment based on the equipment records available at the time. When later inspections revealed corrosion inside several pipes, the company ordered a reassessment of the factory's operating risks.
What does the relationship between "assessment" and "reassessment" indicate about the company's action?
- The company rejected evaluation as unnecessary once physical evidence became available.
- The company evaluated the risks again because new evidence could alter its earlier judgment. (correct answer)
- The company reduced the seriousness of the risks identified in the original evaluation.
- The company transferred responsibility for the original evaluation to another organization.
Explanation: When a question asks about the relationship between two words that share a root — like "assessment" and "reassessment" — your job is to analyze what the prefix changes about the meaning, then connect that shift to the action described in the passage.
The prefix re- means "again," so a reassessment is simply a second evaluation. The passage explains why this second evaluation was ordered: inspectors discovered corrosion inside several pipes, which is new physical evidence that wasn't available during the original assessment. Because this new information could change the company's understanding of risk, they evaluated the situation again. That reasoning maps perfectly onto B — the company evaluated risks again because new evidence could alter its earlier judgment.
A is wrong because the company didn't abandon evaluation — it did the opposite. It ordered more evaluation in response to the physical evidence, not less. C misreads the situation entirely; nothing in the passage suggests the company minimized or downplayed the risks. If anything, ordering a reassessment signals the risks may be greater than originally thought. D introduces the idea of transferring responsibility to another organization, which the passage never mentions at all — this is a fabricated detail designed to tempt students who might confuse "reassessment" with some kind of handoff.
A useful strategy: when a question focuses on a word with a prefix like re-, un-, pre-, or mis-, break the word apart first, then look for why the passage required that variation of the word. The "why" in the passage will almost always point you to the correct answer.
Question 9
The state adopted a new framework for short-term lending. Because the rules apply to firms operating across several counties, lawmakers also created an independent with authority to investigate violations and impose penalties.
Which pair from the regulate word family most precisely completes the passage?
- regulation; regulatory
- regulator; regulation
- regulatory; regulator (correct answer)
- regulated; regulation
Explanation: When a question asks you to complete a passage using words from the same word family, your job is to match each word's grammatical role to what the sentence actually requires. Ask yourself: does this blank need a noun, an adjective, or a verb form?
Look at the first blank: "a new framework." Here, the blank sits between an adjective ("new") and a noun ("framework"), which means you need a word that modifies a noun — an adjective. The word "regulatory" is an adjective meaning "relating to regulation," so it fits perfectly. The second blank follows the article "an independent ," signaling that you need a noun — specifically, something that can be an entity with authority. "Regulator" is a noun meaning a person or body that enforces rules, making it the right fit. That logic confirms C) regulatory; regulator is correct.
Choice A reverses the logic partially: "regulation framework" uses a noun where an adjective is needed, and "regulatory" in the second blank would describe something rather than name it — you can't investigate violations if you're just a describing word. Choice B places "regulator" in the first blank, but a regulator is a person or agency, not a modifier for "framework." Choice D uses "regulated," a past-tense verb or past participle, which doesn't describe a framework in a meaningful way here — frameworks aren't regulated, they do the regulating.
A useful tip: when filling blanks with related word forms, identify the part of speech each blank demands before looking at the choices. Adjectives modify nouns; nouns name things. That single check eliminates most wrong answers quickly.
Question 10
After receiving several hundred comments on the proposed transit plan, the council requested an of the concerns raised. Staff members were instructed not merely to count repeated words but to patterns connecting residents' locations, work schedules, and transportation needs.
Which pair of words from the same academic word family best completes the passage?
- analytical; analysis
- analyze; analytical
- analysis; analyze (correct answer)
- analyst; analysis
Explanation: When a question asks you to complete two blanks using words from the same "word family," you're being tested on grammatical form — specifically, whether you can match the right form of a word to the right job in a sentence. Each blank has a grammatical role, and your job is to identify what part of speech belongs there.
Look at the first blank: "the council requested an of the concerns." The word follows the article an and functions as the object of the verb "requested" — that's a noun slot. Look at the second blank: "to patterns connecting residents' locations." This follows the infinitive marker to, placing it in a verb slot. So you need noun, then verb — which is exactly what answer C provides: analysis (noun) and analyze (verb). That's why C is correct.
Now consider why the others fail. Choice A offers analytical then analysis — an adjective followed by a noun, which gives you adjective-verb, a mismatch for both slots. Choice B offers analyze then analytical — a verb then an adjective, which reverses the roles entirely; a verb can't follow an, and an adjective can't follow to in this construction. Choice D offers analyst then analysis — two nouns, and while analyst (a person who analyzes) could theoretically follow an, "to analysis patterns" is grammatically broken because analysis is a noun, not a verb.
A useful strategy: before looking at the answer choices, read each blank independently and ask yourself what part of speech belongs here? Label the slots first (noun, verb, adjective), then match — this prevents you from being distracted by words that look related but play the wrong role.
