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.

Example Input: The 4 pounds of sliced meat itself are contained in a single cardboard box; no vacuum seal or even plastic wrap.  That box is placed in another box that is lined with styrofoam sides, styrofoam peanuts, and three frozen "ice" paks.  It was shipped FedEx 2 Day (that's what the label says), not Overnight or next business day, which begs the question, what exactly did the $52 in shipping charges for 4 lbs of meat and minimal packing materials actually go towards?  I think I know, and it wasn't shipping.  Years ago "Grecian Delight" (the brand on the box) was sold in a local supermarket chain in Gyro Kit boxes - each contained a pack of sliced gyro meat, one pita, and a small container of tzatziki sauce.  I loved them, but I haven't seen the kits in decades and was happy to find a way to once again stock the freezer with gyros-in-waiting.  The gyro meat itself, which I have ordered before, tastes just like ... gyro meat!  As I said, I love gyros, but there's no place nearby where I can drop in and enjoy one.  So I have ordered the product in the past, but in this case, I've ordered for the last time.  I've gotten the individual 1 lb vacuum packets before 3 at a time and they've arrived frozen or nearly frozen. Not so this box.  The meat was not only thawed, it was only slightly cool. I'm afraid I'm going to be throwing it out.  Too risky.  For $52 shipping charges, it should have arrived in perfect condition. Overnight. I won't make this mistake again.  I can't afford to.
Example Output: Negative

Example Input: If you follow their recipes precisely, with careful measurements, the freezer jams are excellent.  Strawberry jam is particularly appealing.  I've been warned that changing quantities of any ingredient will not have happy results.
Example Output: Positive

Example Input: I used to like this product until I learned that it is made in China!  How many more horror stories do we need to hear about such atrocities as lead in baby toys made in China, contaminated baby formula made in China, contaminated tooth paste made in China, and poisoned pet food before we learn that -- if it comes from China-- it should not go in your mouth, your baby's mouth, or your pet's mouth??!!!
Example Output:
Negative
