Example Output: Negative

Example Input: I love the style of the bra, however I ordered a 46D in Black and the cup size of what I received was almost double in size. The label read 46D (which I know I wear), but had to send it back because the cup was just too LARGE.
Example Output: Negative

Example Input: I purchased this book because I was writing a novel about the Native Americans who lived in the Finger Lake region f New York State. The book was helpful as far as gaining some insights into the life styles of these people. I really was not reading this book for its entertainment value.

Positive
