Nowadays mass media there (dlaczego 'there') are full of positive and negative sourceS of inspiration. Wherefore (nie 'wherefore' tylko moze 'therefore')a lot of teenagers look for THEIR own role modelS.
So I agree with the statement, that youth TODAY need the right autorities for a vARiety of reasons. (zamiast authorities - mozna -authority figures)
