Input: Consider Input: A classic story based on history. One of Hypatia's crimes appears to have been ready to provide a hypothesis of a heliocentric universe, long before Copernicus and with a much worse response from the Christian community.

Output: Positive

Input: Consider Input: It was interesting to read The Foxes of Harrow again, as a "senior citizen, since I was only in my early teens the first time I read...and enjoyed...the book. It is quite sensual, considering the year it was written. It has held up fine during the years. I probably understood the nuances better as an adult than as a teenager. Frank Yerby was a brilliant writer, and in this book he presents a balanced view of what white slave owners and their slaves faced during that pre-civil war era. I couldn't help comparing it with Gone With the Wind as I read it.

Output: Positive

Input: Consider Input: My health condition requires frequent monitoring of my temperature. The inexpensive thermometers were inconsistent and replacement batteries were hard to find. The Sure Temp Plus 690 costs more, but is very accurate, easy to use and AA batteries can be purchased anywhere. I feel confident in the readings. A back lit display would be nice, but is not essential. It probably would run down the batteries faster. I would recommend the item to anyone needing fast and accurate temp readings.
Output: Positive
