Answer:
Completely ready
Step-by-step explanation:
Adverbs are words used to modify adjectives, verbs, or other adverbs and express relations of place, time, circumstance, manner, cause, degree, etc., for example, loudly, angrily, quickly, very, well...
Adjectives are words used to modify nouns and noun phrases, for example, beautiful, red, big, loud...
The only adverb in the given sentence is completely, and we can see that the adjective it modifies is ready (To what extent are the members of the academic team ready? They are completely ready.). The only other adjective in the sentence is academic, and the adverb completely is not related to it in any way.
