Example Input: This book was purchased as a supplement to our studies. I felt it wasn't organized very well and the questions were not related very well. It does have some good information, but needs re-organization. We got better responses with another study materials we bought instead. If you know what your studying about before doing this book, it's okay. Just don't rely on the answer sheet in the back. The other sources that we found help quite a bit. Overall it is worth what i paid for it.
Example Output: Good Review

Example Input: I ordered this for my son just prior to his first semester in college and was a great addition to the dorm room. It is as pictured on Amazon so if you are looking at these items, stop right there. Also, there wasn't any instruction manual; however, it took about 5 minutes before we figured out that the top of the microwave had something hanging underneath. There were two tabs underneath one which came off with no difficulty (easily removed by pulling up) but would have been harder without the tabs.
Example Output: Good Review

Example Input: While the premise of this book is great, there are no photos and only black & white photos. I was expecting that to be included in a new release, but found it out after reading that it's not. Not sure why they didn't include at least an actual photo for each breed. Very disappointed- I'll check back with my order status next week hoping someone can correct this. If not...I'm sending back.
