Difficulty: HardPrefix and Suffix Analysis

The audit committee presented incontrovertible evidence of full compliance during the inspection. In this context, which of the following is the closest synonym for the word incontrovertible?

  1. indisputableAnswer
  2. B
    debatable
  3. C
    controversial
  4. D
    transformable

Answer

indisputable
The word 'incontrovertible' is formed by the negative prefix 'in-' (not), the prefix 'contro-' (against), the root 'vert' (turn), and the adjective suffix '-ible' (able to be). Together, 'controvert' means to argue against or deny, so 'incontrovertible' literally describes evidence that cannot be denied, making 'indisputable' the correct synonym.

Step-by-Step Solution

1
Isolate the prefixes and suffixes in the target word 'incontrovertible'
Identified negative prefix 'in-' (meaning 'not'), secondary prefix 'contro-' (meaning 'against'), root 'vert' (meaning 'to turn'), and suffix '-ible' (meaning 'capable of being')
Deconstructing the word into its morphological components reveals the underlying structural definition
2
Synthesize the affix and root meanings to deduce the literal definition
'Not capable of being turned against or disputed', meaning undeniable or certain
The base 'controvert' means to dispute or argue against; adding 'in-' and '-ible' forms an adjective meaning unable to be disputed
3
Evaluate the choices to match the synthesized definition
The term 'indisputable' directly corresponds to something that cannot be questioned or disputed
Matches both the grammatical category (adjective) and the exact morphological meaning
