Example Input: Why in the world would Amazon want to sell an item and say can be ingested,  when it clearly has ingredients that can cause cancer. Wish every state would wake up like California and ban all these cancer causing things.
Example Output: 2

Example Input: I had high hopes when I purchased this produce, shipping was amazingly fast and I've tried it a few times. I don't enjoy the taste, and since I don't sweeten my tea, it wasn't that great, and it did nothing for my sinuses. Will not purchase again but I do recommend the seller.
Example Output: 2

Example Input: We have tried just about every k-cup of regular coffee out there.  We don't do the flavor kind.  My husband loves the GM brand most of the coffees are mild (even when they say medium roast)...I go for a little more on the medium roast like the some of the Tully's and Caribou brands.  It used to be that we were always ordering the same brands, once we liked a certain one.  But I ventured to try the Wolfgang Puck line.  While this flavor is touted as a medium roast, it seems to be more on the bold side with a little bitterness.  It is still not a bad coffee, just not as good as the "Rodeo Drive" or "Breakfast in Bed" k-cups which has no bitterness.  I must say though, we have now added the latter 2 flavors of Wolfgang to our buying ritual.
