Choose the word that best completes the sentence: Although the committee's report was widely praised, several members felt its conclusions were ______, resting on a single dataset that had never been independently replicated.

Answer and explanation

Correct answer: B. tenuous

  1. Step 1: The clause 'resting on a single dataset ... never replicated' signals weak support for the conclusions.
  2. Step 2: The word must therefore mean weak or poorly supported: 'tenuous'.
Answer
tenuous.
Why not the others: 'Robust', 'exhaustive' and 'incontrovertible' all describe strong, complete or undeniable findings, the opposite of the context.
