Example Input: not bad but be warned you need to buy extra play-doh at local store before handing it to the kid's
Example Output: Positive

Example Input: Here are the problems with using this in the classroom:1. The lines are not numbered, so students will have to number the lines as homework for every scene, or else you'll waste a lot of class time doing this.2. The paper quality is terrible for annotating: Mechanical pencil lead gets caught on the fibers, and any ink but ballpoint pens spreads out.3. Very few terms are annotated in the book, so you'll need to keep your own glossary inside the front cover because there's very little space to annotate.4. Prestwick House has an annotated copy with line numbers, plenty of space in the margins, high-quality paper, scene-by-scene glossary in the back, reader's tips for reading Shakespeare, and extra textbook-type help. Guess how much: 99 cents!
Example Output: Negative

Example Input: NEGATIVE: This game does not work with OS X and requires the CD so you can't have it on multiple computers. It is slow I have to tell my daughter that it is thinking a lot, this is because it has to access the CD everytime there is a new task. You can't view the openning sequence again without throwing out the saved game files. Some of the tasks and controls are too hard and not user friendly even for adults.it CRASHES all the time.Mouse is jumpy and hard to use.POSITIVE: Some tasks are easy, possible to use, grand and beautiful.My three year has enough patience to survive the multiple trials to get this to work.
Example Output:
Negative
