Example Input: I was pleasantly surprised to find this book so readable- even by modern standards it is a good read, although the language in parts is somewhat old-fashioned, archaic even ..... but if you can deal with that, this is a good bet for anyone who would like a tale of England in the late 1600's... love, adventure, and even a little humor too!
Example Output:
Positive
