If you go to the main thread for the second challenge, there's a list of who's poisoned on both teams. Basically, once this event is over, everyone who's poisoned will be eliminated. If we get the most correct answers in this challenge, we get the chance to remove the poison from half of our poisoned team members (whether that'll be 1 or 2, I don't know), though that still leaves at least one to be eliminated. If we get the same amount of correct answers though, there's not really any hope for the poisoned people.
