TASK DEFINITION: In this task, You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.
PROBLEM: This is a piece of crap have only had a week and there's no more motion I don't write reviews but this is straight garbage I will be returning this. Don't waste your money on this one. I would give it no stars if I could. Very disappointed

SOLUTION: negative

PROBLEM: Arrived promptly. I received it today and began taking immediately. It contains so many vitamins, such as A, C, D3, E, B6, Folic acid and of course biotin, etc. I believe in this product and hope it will deliver promising results.

SOLUTION: positive

PROBLEM: They work pretty well. Wasn’t sure what to expect but it’s nice not having to think about my socks or shirt bunching up all day. I can reach up high to grab a book off of a bookshelf for instance and my shirt tucks itself back in.

SOLUTION:
positive
