Question

What is the meaning of the word 'irrefutable' as used in the given passage?

• A. indefinite
• B. dubious
• C. questionable
• D. indisputable

Hint:

For vocabulary-in-context, always replace the word directly in the sentence and check which option fits without changing the meaning.

Answer 1

The Correct Option is D

"Irrefutable evidence" means evidence that cannot be denied, disproved, or questioned. Thus, the closest synonym is "indisputable." Options (a), (b), (c) all convey uncertainty, which is the opposite of "irrefutable." \[ \Rightarrow \boxed{(d)} \]

Answer 2

Breaking the word into its parts gives a reliable way to pin down the meaning without relying on memorised synonyms. "Irrefutable" is built from the prefix ir- (not), the root refute (to prove wrong), and the suffix -able (capable of). Put together, it literally means "not capable of being proved wrong."

1. Option 1 (indefinite): This means vague or not clearly defined, describing something lacking precision, not something that cannot be disproved. Ruled out.
2. Option 2 (dubious): This means doubtful or open to suspicion, almost the reverse of something that cannot be challenged. Ruled out.
3. Option 3 (questionable): This means open to doubt or debate, again the opposite sense of something beyond dispute. Ruled out.
4. Option 4 (indisputable): Literally "not able to be disputed," which lines up exactly with the "not able to be refuted" sense derived from the word's parts.

Only option 4 carries the "cannot be disproved" sense built into the word itself.

Hence, the correct answer is indisputable.
