How were they meant to guess the berry from an overdramatic "death".

Did the student volunteers even know what the berries were and what they did? Was Jessa's portrayal an accurate portrayal of how someone would react to that berry? Was a single berry even enough to poison someone?! This didn't make sense to her. These classes never did.

Her eyes glanced back over at the girl who was now slumped on the ground. Time to wait for the other portrayals. And then the answer.
