Gulliver is asked to demonstrate "some proofs of [his] prodigious strength." Which word is an antonym for prodigious? A. ordinary B. exceptional C. stupendous D. superior

The answer is A.

Explanation:

First, let's define antonyms - they are words of the opposite meaning (small-large)

Prodigious means being immense, great, stunning, amazing and etc. So other answers: exceptional, stupendous and superior can relate in some way with prodigious, so we can say they are synonyms (words of the same or similar meaning).

The only word that means the opposite is ordinary, so this is the antonym we are looking for.
