Example Input: I believe Robert Kagan's "The War for America" series continues this tradition with volume 1, detailing both the origin and historical context of U.S. history since WWII.
Example Output: Good Review

Example Input: Nice size, easy to handle, and makes great hot water. I was hesitant at first because the price seems high, but well worth it! Now my mother can brew her favorite tea by herself. I gave it a 4/5 only because its difficult to determine how much water is needed. Also, you have to open one part of this pot each time after brewing (not very convenient) which does not make me love it any less. Overall, though, really nice product.
Example Output: Good Review

Example Input: This is definitely an interesting perspective from both a male & female perspective.
Example Output:
Good Review
