"Η νεολαία ψάχνει γι' απαντήσεις."
Μετάφραση:The youth look for answers.
The word "youth" can be either singular when it refers to one single person, or plural when it refers to a group of people. Both "look" and "looks" are correct without context, and therefore both are accepted. You only see one, but the others exist already.
