Teacher: Given a 'poster' sentence and a corresponding 'response' (often, from Facebook or Reddit)classify the sentiment of the given response into four categories: 1) Positive, 2) Negative, 3) Neutral, and 4) Mixed if it contains both positive and negative.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Poster: Stopped by Fashion Week and got to hang with Amber Fillerup (Barefoot Blonde) at Lauren Conrad's runway show. Kohl's #LCRunway   Responser: You are Both Sweet Ashley Tisdale and Lauren Conrad
Solution: Positive
Reason: The responser is praising the poster.

Now, solve this instance: Poster: Besides it sheer size (48 miles of man made waterway with five locks) the history and utter determination to get the Panama Canal built is inspiring. The third set of locks opened for larger ships and supertankers on June 16th, and is more massive than the locks seen here.  Responser: Did you know the second engineer on the Panama Canal project who lead its completion was George Washington Goethals? And why is that name familiar?
Student:
Neutral
