Ex Input:
Dynasty brand green tea is the best green tea I've ever tasted.  It never tastes stale, unlike brands I've bought in grocery stores.  This is because each tea bag is packed in a sealed envelope with a metallic lining.  The metal apparently keeps out moisture.

Ex Output:
Positive


Ex Input:
I got the licorice at a cheese shop in New York and by the time I got home it was all gone. So got on the computer and found and bought some. That's how much I liked it. I have not done the before and do not regret buying it. Yummmmmm.

Ex Output:
Positive
