Input: Consider Input: I like the book Castle In the Attic because it was very adventurous. My favorite part in the book was when Mrs.Philips gave William a gift. Do you know what the gift was? Can you figure out what it is? I recommend this book because Castle In the Attic is a very exciting novel to read.

Output: Positive


Input: Consider Input: This video is fine for ballroom dancers, but it has nothing to do with the authentic Argentine Tango. Even ballroom dancing has now a separate category for Argentine Tango. Unfortunately, this video is not that. That's why, I rate it at 1.

Output: Negative


Input: Consider Input: In reviewing the book Foundation I am recommending that you read all of the Foundation books by Asimov. Just get started and read them all. Even though each book can be read individually, do yourself a favor and read them in order. I won't be reviewing any other books in the series. I want you to do the whole series.One of the most interesting ideas that Asimov gives us is the ultimate form of self defense. No, it isn't karate or jiu jitsu, boxing or wrestling. It's touching the other person's mind.There are enough circles within circles, things that aren't what they seem to be, surprises that put the theories into a cocked hat, to keep you on your toes.Don't deprive yourself of the best sci fi series ever written.


Output: Positive
