Ex Input:
This book was interesting with great promise. The premise was fascinating but the writer fought with herself throughout. She spent a great deal of time on the flora and the fauna. There was always a paragraph on a bush when a sentence would do, a sentence on a tree when a word would suffice. The characters were well developed. Over all it was a good read.

Ex Output:
Negative

I got these for my jawbone headset. Many had said they work great. but for the life of me i cant figure out how you get them to work short of superglue and even then they are too quiet to hear so i guess they work on the jabra they are designed for but not the jawbone.

Ex Output:
Negative

This book was great! Lots of old Dear Abbey letters with background information on the thoughts that were behind the answers.
