Difficulty: EasyValidating Sentence Coherence and Pair Equivalence

Although the researcher's preliminary findings were initially greeted with skepticism, subsequent large-scale clinical trials served to ________ her hypothesis, earning her widespread acclaim within the scientific community. Which TWO of the following answer choices, when inserted into the blank, produce completed sentences that are logically coherent and substantially equivalent in meaning?

  1. vindicateAnswer
  2. corroborateAnswer
  3. C
    invalidate
  4. D
    obfuscate
  5. E
    publicize
  6. F
    scrutinize

Answer

The sentence is completed coherently and with equivalent meaning by choosing 'vindicate' and 'corroborate'.
The structural marker 'Although' indicates a contrast between initial skepticism and the positive outcome of 'widespread acclaim'. Therefore, the blank requires verbs that mean to validate, support, or prove true. 'Vindicate' and 'corroborate' both fulfill this contextual requirement and produce sentences that are equivalent in meaning.

Step-by-Step Solution

1
Analyze structural clues and sentence polarity.
The sentence begins with the concession transition 'Although', indicating a contrast between initial skepticism and the later outcome that resulted in 'widespread acclaim'.
The blank must contain a word meaning to prove correct, validate, or confirm in order to resolve the contrast.
2
Evaluate candidate words for contextual fit.
'Vindicate' (to clear from blame or prove right) and 'corroborate' (to confirm or give support to) both fit the context of confirming the hypothesis.
Both words accurately reflect how clinical trials resolved earlier doubts.
3
Validate semantic equivalence of the selected pair.
Both completed sentences convey that subsequent trials confirmed the researcher's hypothesis, producing identical sentence meanings.
Selecting 'vindicate' and 'corroborate' satisfies both sentence coherence and pair equivalence criteria.
