read this sentence from paragraph 10.
“the best advice is to practice your presentation so much that you could do it in your sleep,” calandrelli said.
the idiom in this sentence suggests that students should
○ get plenty of sleep the night before giving a presentation.
○ give their presentations in front of a small audience first.
○ take advice from their teachers on how to write a presentation.
○ memorize their presentations before they give them.

Explanation:

The sentence says to practice the presentation so much that you can do it in your sleep, which implies memorizing it thoroughly. Option A is about sleep before presentation (not the focus), B is about teacher advice (not mentioned), C is about small audience first (not related). So the idiom suggests memorizing presentations before giving them.

Answer:

O memorize their presentations before they give them.
