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: I've been a longtime fan of Mercedes and own most of her Valdemar series. So, of course, I picked this book up at my local store. After wrestling through 50 pages, I gave up! I plan to sell it back to my local store ASAP- this is nothing better than a paperweight in my bookshelves. The worst part is, my boyfriend picked it up and tried reading it. Now he thinks that this is a good example of her work!

Output: Negative


Input: Consider Input: Opened the box, unrolled the mattress, plugged in the motor and then... the motor made a few feeble noises and shut off in less than three seconds. Plugged it into several different outlets with the same results.Intex customer service told me that there are NO WARRANTIES on their air mattresses and the only option was to return it to Amazon for a refund. I will not be ordering any products from Intex in the future.


Output: Negative
