Помогите! Со заданием 2)

I thunk that Jenny is a heavy TV viewer. She also said that she watches TV while doing her homework. I think that it`s not right. Because when you do something important, you have to concentrate on this. As for me, I watch TV only an hour a day and that`s why I feel rather good and have no problems with healt. But Jenny realy need to care about herself.
