Teacher: In this task, 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
These are junk! Both bulbs have burned out within a two month period!! I cannot believe that this company can be in business with such poor quality. I have used infrared lights for my ball python for many years now and I get a varied range of months from a bulb, but I have never gone through two bulbs in a matter of two months! I am very disappointed.
Solution: negative
Reason: The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, it's a negative review.

Now, solve this instance: I have osteo arthritis and torn meniscus in both knees and bought these to wear daily just to give me some support and warmth during the day. They have actually surpassed my expectations and have calmed my knee pain considerably. Doing things like walking up and down stairs are now bearable and I no longer appear to be an 80 year old man. They are comfortable to wear all day and I actually forget they are on. I am not for a minute suggesting they have cured me of all my ills, but they have made a huge difference in my day to day activities. I have even been able to return to boxing training (with some modified activities). This is a minor miracle thinking back to the pain my knees were generating when trying to train at any level. I will be ordering more pairs just in case they disappear from the market.
