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." 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.
Example Output: Negative

Example Input: Kudos to the Hi-Tec designers & manufacturers! My husband wears these daily for all types of situations. Easy to keep clean and looking nice. VERY durable. Almost no time to "break them in". Design has stayed constant. Run true to size. No need to change something that already works great. Will continue buying these in the future.
Example Output:
Positive
