The scholar quoted irrefutable evidence for her thesis.
- (a)overwhelming
- (b)undeniable
- (c)certain
- (d)questionable
Correct — D, questionable. To refute a claim is to prove it false, so irrefutable evidence is evidence that cannot be proved false at all. Reverse that and you get evidence open to doubt and argument — 'questionable'. Undeniable and certain restate the strength of the evidence, and 'overwhelming' praises it too.
- (a)overwhelming — 'Overwhelming evidence' is such a familiar pairing that the phrase pulls the eye, but it means evidence too strong to resist — agreement with the tested word, not opposition.
- (b)undeniable — 'Undeniable' is the closest synonym on the list, since what cannot be denied is what cannot be refuted.
- (c)certain — 'Certain' means established beyond doubt, which puts it on the same side of the argument as 'irrefutable'.
An antonym item on 'irrefutable' — impossible to disprove — whose reverse is 'questionable', meaning open to doubt.
Break the word apart before scanning the options. The stem 'refute' means to prove wrong, -able adds the possibility, and ir- cancels it, so irrefutable means it cannot be proved wrong. Only one printed choice restores the possibility of proving it wrong. Collocation is the trap here, because 'overwhelming evidence' feels like the right neighbourhood while taking the wrong side.
- 'Refute' means to prove a statement or a person wrong; the prefix ir- cancels the ability.
- Indisputable, incontrovertible and undeniable are near-synonyms of 'irrefutable'.
- Careful writers keep 'refute' (disprove) apart from 'deny' (merely reject).
- Picking 'overwhelming' because 'overwhelming evidence' is such a familiar phrase.
- Picking 'undeniable', which is a synonym of the tested word.
