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: Really good construction, not the usually cheap plastic feel. I love the multiple colors on each truck. The return mechanism is really nice and fun. It's a must buy for every child!

SOLUTION: positive

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: Mine leaked after using it for a week. I thought it was surely something I did wrong, but everything was nice and tight and yet it leaked. Unfortunately, it was in my bag at the moment, so it leaked all over everything. What a shame! I was really enjoying it... well until it leaked. Not sure what happened, so can't give you more details, but certainly is not something I would try again.

SOLUTION:
negative
