Ex Input:
It is curious that one one the more significant achievements of "Pastor" Charles Taze Russell is omitted above. That fact is that he was the primary founder of the Watchtower Bible and Tract Society, and the religion now known as "Jehovah's Witnesses." No small amount of his theology is controversial in the body of the Church as a whole, as it would be (for different reasons, perhaps) amongst Jehovah's Witnesses.

Ex Output:
Negative


Ex Input:
I was totally disappointed with the book for two reasons. One, it had a different author than the one I ordered. Two, it was tremendously boring. A waste of the little money I did spend to get it.

Ex Output:

Negative
