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.

Ex Input:
Despite what the previous, obviously fake reviews claim this product doesn't do anything to prevent hangovers.  Drink water instead and save yourself $24.  No such thing as "toxins".  Psuedoscientific snake oil.

Ex Output:
Negative


Ex Input:
This was the first time I tried purchasing a food product over the internet, and as feared I was sent something other than what was pictured.  This package contains Chia Seed POWDER, which I assume is ground up seed (or the remainder from packaging whole seeds) that you have no way of identifying whether or not has additional filler.  Not going to bother returning a $7 product, but just disappointed when the page advertises whole seeds.

Ex Output:
Negative


Ex Input:
I emailed customer service and asked if the treats were filled with sweet potato, and they assured me that they'd checked with the manufacturer and confirmed that they did in fact have a sweet potato center.  However, the ones I received did not and I feel like I was lied to by customer service because they didn't want to take the time to actually check into it.

Ex Output:

Negative
