Example 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."

Example Output: Negative

Example Input: My 3 year-old niece loves to dress up, so we got her this costume for Christmas. She loved it and spent the rest of Christmas vacation wearing it.
