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 Q]: 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 A]: Negative

[EX Q]: I am the biggest fan of mushrooms you'll ever meet, but these are really disgusting. They taste like dirt. I have to imagine better quality truffles (if these are even truffles at all) are muuuuch better. They'd have to be. There'd be no comparison. These are really bad.
[EX A]: Negative

[EX Q]: I was looking for a good sweet and sour sauce for chicken and based on the reviews, I took a chance.  Well, no one in the family likes this stuff- it tastes nothing like sweet and sour sauce- more like what it says it is- Chili Sauce.  Now I'm stuck with two huge bottles.  Sometimes reading the label is really all that matters.
[EX A]:
Negative
