How do you answer rank7s question in megaman battle network white 3

Technically, it's the abbreviated version of a question: a quest. You are to FIND "one of many birds" and bring it back to prove your intelligence. If you're one of those people that examines everything, you'll have a pretty good idea already. If not, then the quest refers to the origami birds in what is/was Mamoru's room in the hospital.
