Input:
I use this thermos everyday. It is soooo useful! With the top on I can throw it in my purse without it leaking. It travels well, being the perfect size to discretly take to meetings. It keeps coffee hot for a very long time. It fits in most beverage holders and if riding in someones car without one, I close it up and leave it on the floor when I need to put it down. I think it is well worth the investment to own one.

Options:

B: positive
C: neutral
D: negative
E: very negative
Answer: A: very positive
