The new environmental regulations were designed to ______ the toxic runoff from manufacturing plants into local water systems, thereby preventing further degradation of the aquatic ecosystem.
Show Official Answer & Step-by-Step Rationale
Correct Answer:curb, check
Step-by-Step Proof:
The sentence states that the regulations aim to prevent "further degradation of the aquatic ecosystem." The blank must mean to restrain, limit, or stop the runoff. Both "curb" and "check" mean to restrain or hold back. Foster and promote mean the opposite. Exacerbate means to worsen.
🎯 Key Rule:
"Check" and "curb" form a quintessential GRE synonym pair meaning to restrain.
Because the executive was accustomed to unquestioning deference from his staff, he found his deputy’s outspoken disagreements not merely unhelpful, but downright ______.
Show Official Answer & Step-by-Step Rationale
Correct Answer:audacious, insolent
Step-by-Step Proof:
The prompt establishes a strong context: someone used to "unquestioning deference" will perceive outspoken disagreements as brazen disrespect. "Audacious" and "insolent" both convey bold, arrogant disrespect. "Diffident" and "submissive" are direct antonyms of the intended tone.
🎯 Key Rule:
Always verify that both chosen words match the logical tone AND create identical sentence meanings.
Though his public speeches were marked by an expansive, even theatrical eloquence, his private correspondences revealed a man who was remarkably ______ in discussing personal tribulations.
Show Official Answer & Step-by-Step Rationale
Correct Answer:laconic, taciturn
Step-by-Step Proof:
1. The pivot "Though" contrasts his public "theatrical eloquence" (talkative, expressive) with his private manner.
2. The blank must describe someone who says very little or is reserved about personal matters.
3. "Laconic" (using very few words) and "taciturn" (habitually silent or uncommunicative) complete the contrast and produce equivalent sentences.
Trap alert: "Garrulous" and "loquacious" also form a perfect synonym pair (both mean talkative), but they match the wrong side of the contrast!
Common ETS Trap Warning:
ETS intentionally places "pair traps" in Sentence Equivalence: pairs of words that are synonyms of each other (garrulous/loquacious) but logically contradict the sentence clue.
🎯 Key Rule:
Never pick synonym pairs blindly without checking whether their meaning satisfies the contextual clue.
Far from being a mere ________ chronicle of events, the historian’s latest volume functions as an impassioned defense that selectively interprets documentary records to vindicate a controversial political figure.
Show Official Answer & Step-by-Step Rationale
Correct Answer:dispassionate, objective
Step-by-Step Proof:
The sentence begins with the contrast phrase 'Far from being a mere ________ chronicle', which must set up an antonymous relationship with the subsequent description: 'an impassioned defense that selectively interprets documentary records to vindicate a controversial political figure.' Because the book is biased, polemical, and selective ('impassioned defense', 'selectively interprets'), the blank requires an adjective describing a neutral, unbiased, or detached account. 'Dispassionate' (free from emotion or bias) and 'objective' (not influenced by personal feelings or opinions) form an exact synonym pair that creates two semantically equivalent sentences.
Common ETS Trap Warning:
ETS frequently includes a pair of synonyms that describes the actual nature of the subject rather than what it is contrasted against. Here, 'tendentious' and 'partisan' form a synonym pair meaning biased or promoting a specific cause; test takers who miss the negative pivot 'Far from being' will fall into this trap. Additionally, 'comprehensive' and 'exhaustive' form another distractor pair referring to thoroughness, which often describes historical chronicles but fails to oppose the subjective and emotional tone of an 'impassioned defense.'
🎯 Key Rule:
Pay close attention to initial contrast pivots like 'Far from being,' which require words opposite in meaning to the main clause description.
Rather than providing a definitive explanation for the ancient settlement’s sudden abandonment, the archaeological findings have proved surprisingly ________, confounding researchers who had anticipated clear and conclusive evidence.
Show Official Answer & Step-by-Step Rationale
Correct Answer:equivocal, ambiguous
Step-by-Step Proof:
The sentence establishes a contrast signaled by 'Rather than providing a definitive explanation' and bolstered by the outcome 'confounding researchers who had anticipated clear and conclusive evidence.' The blank must characterize findings that are the opposite of 'definitive,' 'clear,' and 'conclusive.' Both 'equivocal' (open to more than one interpretation; uncertain) and 'ambiguous' (open to multiple interpretations; having a double or obscure meaning) precisely capture this state of inconclusiveness and result in equivalent, coherent sentences.
Common ETS Trap Warning:
The answer choices are engineered with three distinct synonym pairs: (1) 'equivocal' / 'ambiguous', (2) 'instructive' / 'revealing', and (3) 'peripheral' / 'tangential'. Test takers who overlook the contrast indicator 'Rather than' might be tempted by 'instructive' and 'revealing,' which match a positive archaeological discovery. Those who focus vaguely on unhelpfulness might select 'peripheral' and 'tangential,' but these mean irrelevant or incidental, whereas the prompt specifically concerns the lack of clarity and definitiveness in the evidence itself.
🎯 Key Rule:
When multiple synonym pairs appear in the options, match the precise semantic nuance dictated by the contextual antonym (here: 'definitive' and 'clear and conclusive').
