Example Input: I'm sure these are great socks, but I was slightly disappointed when I thought I was getting 3 pairs for the price listed...my package arrived and there was only one pair for the stated price. I feel like the image with 3 socks was deceptive and "false advertising", as it states nowhere else how many pairs are sold for the stated price. Hope I enjoy the socks, but thought I'd warn everyone else before they buy these and expect more than what you'll receive.
Example Output: Negative

Example Input: What a pleasure to read such a high-quality book... It introduces each of the islands in a colorful and vivid way. The book includes many pictures, and provides a fine insight into the culture and character of the islands and touches on history, people, travel, activities, sights, nature, and a lot more.However, if you are looking for a book with accurate travel information, e.g. hotels, restaurants, prices/dates, how to get there, etc., this book is on the weaker side. Use it together with the Frommer's Caribbean guide for a combination that is hard to beat. Despite this weakness, it's still a five star on my bookshelf.
Example Output: Positive

Example Input: These wraps were not doing anything when we placed them in "hot" water. We searched the internet and found others having the same problem. The instructions are very poor. First off, you need to dip in boiling water (or at least some temperature level above what I would call hot). Second, the instructions don't describe what should happen, should the image shrink around the egg, transfer to it -- what?Needless to say, it was frustrating for a minute or two, but my wife - who is very intelligent and great in the kitchen - immediately thought, "well... hot water wouldn't do much to change the properties of the plastic, so let's try boiling water - nothing to lose."Should be more explicit in the instructions. (We were using the star wars version of this product).
Example Output:
Negative
