Example Input: This toy is not that great for my pug. He loves finding stuff in the little cups, however the yellow covers are impossible for him to get off. His mouth won't fit around them so he can't pick them up with his teeth, when he uses his nose to try to get at them the cups just fall back into place and if he uses his paws (that's when he's really frustrated) he winds up just flipping the whole thing over. I have turned the cups upside down so that he can grab at the edges and that works for him. However, it's not really a puzzle because he even figured out that if the cup is sticking up, something is in there. I even have a hard time getting some of the cups out because of the way it is shaped. It's not a bad toy as a starter puzzle but if your dog has done puzzles before, this one won't keep him interested. And if you have a dog with no snout, it's not really worth it.
Example Output: Negative

Example Input: This is a confection that has been around a few centuries.  It is a light, pillowy citrus gelatin with nuts - in this case Filberts. And it is cut into tiny squares and then liberally coated with powdered sugar.  And it is a tiny mouthful of heaven.  Not too chewy, and very flavorful.  I highly recommend this yummy treat.  If you are familiar with the story of C.S. Lewis' "The Lion, The Witch, and The Wardrobe" - this is the treat that seduces Edmund into selling out his Brother and Sisters to the Witch.
Example Output: Positive

Example Input: Tastes too sweet, which Jerk Seasoning is not.  Walker's woods is the most authentic to taste.  This was a waste.
