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.

Input: Consider Input: I had been buying these treats for my cavachon for the past two years. He loved them.  The last batch was of noticeably lower quality...dry and crunchy rather than moist and chewy. I don't know if this is due to the shift in manufacturing from the US to China or coincidental. In any event, I will not be buying these any more and have switched to other treats.  Note, Amazon would not let me return this item, and I am within the 30 day purchase period. I'm not pleased.

Output: Negative


Input: Consider Input: Unfortunately, I somehow stumbled upon this product and, based on all the glowing reviews, bought a case.  Upon opening the first bag and eating a couple, I was disgusted by the taste.  Worst thing I've ever ordered from Amazon---and I've ordered a lot.  I don't think the nutritional values are all that great, either.

Output: Negative


Input: Consider Input: In order for tea to be labeled "decaff" is must be under 0.4% caffeine when residue levels are tested.  A tea at 2% caffeine is not decaff.  Non-decaff tea is anywhere between 3-5% caffeine.  So ...  at 2% caffeine, this is a caffeinated tea, with caffeine slightly less than what is naturally present in the tea leaf.


Output: Negative
