7 example questions with full explanations. Use the interactive practice above to work through the complete set.
Question 1easy
The following sentence contains one blank. Four pairs of words are offered as options. Select the pair in which BOTH words complete the sentence logically AND produce sentences alike in meaning.
The laboratory results were _______, suggesting that the compound might be an effective treatment, though further trials were necessary.
- A.promising / inconclusive
- B.definitive / conclusive
- C.promising / auspicious✓
- D.auspicious / alarming
Correct answer: C
The sentence conveys cautious optimism: the results hint at effectiveness but are not yet confirmed. 'Promising' and 'auspicious' both mean showing favorable signs of future success, making them true synonyms in this context. Option A fails because 'inconclusive' means the results were uncertain or unclear, which contradicts 'might be an effective treatment.' Option B fails because 'definitive' and 'conclusive' contradict 'further trials were necessary.' Option D fails because 'alarming' is opposite in connotation to 'auspicious.'
Question 2medium
Although the new mayor promised sweeping reforms, her first budget was surprisingly _______, allocating funds in almost exactly the same proportions as her predecessor had.
Which pair of words, when inserted into the blank, produces two sentences that are alike in meaning?
- A.modest … humble
- B.derivative … plagiaristic
- C.frugal … economical
- D.orthodox … conventional✓
Correct answer: D
The sentence contrasts promised 'sweeping reforms' with a budget that closely mirrors the predecessor's—meaning the budget adhered to established patterns. Both 'orthodox' and 'conventional' mean conforming to established norms, making them genuine synonyms in this context. Option A fails because 'modest' and 'humble' suggest small scale or self-effacement, not adherence to prior patterns. Option B is a trap: 'derivative' fits in that it implies following precedent, but 'plagiaristic' implies wrongful copying (a stronger moral charge), so the two words produce sentences with meaningfully different tones. Option C ('frugal' and 'economical') describes spending habits, not whether the budget mirrored the predecessor's distribution.
Question 3hard
The Renaissance courtier's memoir, though ostensibly a manual of conduct, reads at times as a _______ for a world of grace and elegance that the author feared was already vanishing.
Which pair of words, when inserted into the blank, produces two complete sentences that are alike in meaning?
- A.elegy / lament✓
- B.paean / encomium
- C.treatise / polemic
- D.allegory / satire
Correct answer: A
The sentence describes something written in mourning for a disappearing world, which is precisely what an elegy and a lament both express: a sorrowful commemoration of something lost or passing. Both words therefore produce equivalent, fitting sentences. A paean and encomium (B) are expressions of praise, not grief, and would contradict the elegiac tone. A treatise is a formal exposition and a polemic is an aggressive argument—neither conveys mourning, and they are not synonymous with each other (C). An allegory is a symbolic narrative and a satire uses irony to critique—neither fits the context of mourning, and they are antonymous in register (D).
Question 4hard
Unlike the classic model of enzymatic catalysis, in which the protein remains _______ across successive reaction cycles, this newly characterized enzyme undergoes irreversible conformational changes after each catalytic event.
Which pair of words, when inserted into the blank, produces two complete sentences that are alike in meaning?
- A.dormant / latent
- B.invariant / unaltered✓
- C.reactive / responsive
- D.depleted / exhausted
Correct answer: B
The sentence contrasts the classic model—in which the catalyst is structurally unchanged—with a novel enzyme that is permanently altered. Invariant and unaltered both precisely convey the idea that the catalyst remains structurally the same throughout successive cycles, making both sentences equivalent. Dormant and latent (A) suggest inactivity rather than structural constancy, and while they are near-synonyms with each other, they do not fit the biochemical context of a functioning catalyst. Reactive and responsive (C) describe a catalyst engaging with substrates—the opposite of the intended meaning. Depleted and exhausted (D) fit grammatically and evoke chemical reactions, but they describe a catalyst being consumed, which contradicts the premise of the classic model being described.
Question 5hard
The biographer's portrayal of the admiral was so _______ that scholars reading the account found it impossible to determine whether the author viewed the subject's aggressive naval strategies as visionary or reckless.
Which pair of words, when inserted into the blank, produces two complete sentences that are alike in meaning?
- A.hostile / antagonistic
- B.laudatory / adulatory
- C.equivocal / ambiguous✓
- D.meticulous / exhaustive
Correct answer: C
The sentence requires a word meaning 'unclear in its evaluative stance,' since scholars cannot determine the author's verdict on the admiral. Equivocal and ambiguous both mean susceptible to multiple interpretations, and both produce sentences with identical meaning. Hostile and antagonistic (A) are synonyms with each other and fit grammatically, but they would imply the biographer's stance is clearly negative—contradicting 'impossible to determine.' Laudatory and adulatory (B) are synonyms but imply clearly positive admiration, again removing the intended ambiguity. Meticulous and exhaustive (D) describe thoroughness of research, fitting grammatically but describing the quality of the account's detail rather than the clarity of its evaluative stance—a contextual mismatch that makes the resulting sentence incoherent with the explanation that follows.
Question 6hard
A test-taker encounters the following Sentence Equivalence item:
"Critics of the new biography noted that the author's portrayal of the general was _____, emphasizing heroic episodes while quietly omitting the documented atrocities for which he was responsible."
The six answer choices are: hagiographic, censorious, eulogistic, veracious, candid, tendentious.
The test-taker correctly identifies that the blank requires a word meaning 'excessively flattering or one-sidedly favorable.' However, they must determine which pair produces equivalent sentences. Which pair is correct?
- A.hagiographic and veracious
- B.censorious and tendentious
- C.eulogistic and candid
- D.hagiographic and eulogistic✓
Correct answer: D
The sentence describes a portrait that praises and omits damning facts, fitting words meaning 'excessively and uncritically flattering.' 'Hagiographic' (literally pertaining to the writing of saints' lives; used figuratively for an uncritically reverent biography) and 'eulogistic' (full of high praise) are genuine synonyms in this context and produce sentences alike in meaning. Option A fails because 'veracious' means truthful and accurate — the opposite of what the context demands, making this a meaning-reversal trap. Option C similarly fails because 'candid' means frank and honest, directly contradicting the author's selective omissions. Option B is the subtlest distractor: 'tendentious' (promoting a biased viewpoint) fits the general sense of bias, but 'censorious' means severely critical or fault-finding — the opposite direction of bias described — so this pair does not produce equivalent sentences and both words do not serve the blank.
Question 7easy
The following sentence has one blank. Four pairs of words are offered as answer choices. Select the pair in which BOTH words complete the sentence logically and produce sentences that are alike in meaning.
The scientist's report was praised for its _______ language: every term was precisely defined, every claim carefully hedged, and no ambiguity was left unresolved.
Which pair best completes the blank?
- A.rigorous / exacting✓
- B.colorful / vivid
- C.provocative / inflammatory
- D.concise / abridged
Correct answer: A
The sentence describes language marked by precise definitions, careful hedging, and zero ambiguity — all hallmarks of strict, demanding exactness. 'Rigorous' and 'exacting' are near-synonyms meaning demanding thoroughness and precision, and both fit the context while producing sentences with the same meaning. Choice B ('colorful / vivid') describes expressive, lively language, the opposite of what is implied by technical precision. Choice C ('provocative / inflammatory') suggests language intended to stir controversy, which contradicts the careful, hedged tone described. Choice D is a trap: 'concise' (brief and to the point) fits the sentence grammatically, but 'abridged' means shortened from a longer original — a different concept entirely — so the two words do not produce equivalent sentences.
