Ex Input:
I'm sure the information presented in this class is good, but the presentation set my teeth on edge. Sheri thinks she is funny when she talks in a screeching voice and makes fun of new mother's foibles in her "funny stories". I cringed every time I heard her squeal as a pretended mother with a problem. If you can get past her, then I guess the DVD can give you the information and techniques you need for Lamaze. But unfortuanately Sheri spends more time talking or shrieking while trying to be amusing than just giving the information you would like to hear.

Ex Output:
Negative

Love the show, which for me has held up well: it's obviously dated but still makes me laugh.What didn't make me laugh, though, was the quality of this DVD. The quality of the transfer, it's as though you're still watching it on VHS! It doesn't support surround-sound, even by just repeating the two channels.There are no subtitles in any language, and no special features of any kind!Worse, mine had scratches right out of the plastic! The scene where Jack comes up to the breakfast table in his speedos is all pixelated. Was that true for anybody else?

Ex Output:
Negative


Ex Input:
Please note that the format of the Chemical PE exam will change somewhat starting in April 2011. This sample exam is based on the old format that was used until October 2010. The problems are still helpful when practicing for the exam, but this book has no longer the same "look and feel" as the new exam. NCEES has a new sample exam book out that matches the new exam specifications and can be ordered from the NCEES website.

Ex Output:

Positive
