Example Input: This stuff sounded perfect...way too much red dye and no taste according to me and my 3 friends who tried it...kind of salty.  Basically, I would stay away from it.  I am tempted to toss it out, but paid too much to feel right about it...
Example Output: 2

Example Input: I was wondering how my cookies which were a spin on the America's Test Kitchen perfect chocolate chip cookie recipe could have come out tasting like crud. Well it was the butterscotch chips. I basically took ATK's recipe and adjusted it for oatmeal insead of the chocolate chip by using their base and adding oats, raisins, chopped mac nuts, cinnamon and these chips. It would have been just as amazing as the chocolate chip cookie recipe if I would have ommitted these chips. Now as another reviewer said, the cookies with the chips in it are destined for the trash.
Example Output: 1

Example Input: Warning to other dog owners: the edible Nylabones are extremely dangerous for dogs with a big & greedy appetite.  My dog swallowed it whole within 30 seconds of giving it to her and choked on it.  She was fully unconscious before I could dislodge the bone and breathe into her nose to bring her back to life... We almost lost her over this bone.  If your dog is a greedy chewer or eater, then please don't buy edible Nylabones.
