Input: Consider Input: I used this program for my science class. My students loved it! They learned some interesting facts, saw damage from earthquakes we talked about in class and never once did I hear that it was boring! Can't beat that!

Output: Positive


Input: Consider Input: This is one of those books that I like the *idea* of, but not so much the execution. It's gotten to the point where if a book has the word "spooky" (or a variation) on the cover, I'm just going to assume it's not. The idea - offering ideas for six themed parties - would make for an excellent book if they were all actually Halloween-themed. Sadly, even the Halloween-specific party suggestions fall a little flat.

Output: Negative


Input: Consider Input: I wanted a reliable second battery for my camera to take on an extended overseas vacation. I was concerned about "OEM" off-brands (which may be OK, but some reviewers advised caution). I was not disappointed by buying the Canon brand named battery which appears to function exactly as my original battery. The Amazon price was much better than I could find locally, and the delivery time was just a few short days after ordering.


Output: Positive
