Teacher: If the emotion of happiness is present in the one of the dialogues of the conversation, then output Yes otherwise output No
Teacher: Now, understand the problem? If you are still confused, see the following example:
So Dick , how about getting some coffee for tonight ? Coffee ? I don ' t honestly like that kind of stuff . Come on , you can at least try a little , besides your cigarette . What ' s wrong with that ? Cigarette is the thing I go crazy for . Not for me , Dick .
Solution: Yes
Reason: Here the first sentence indicates the soft tone and how exciting the speaker is for drinking coffee and it suggests overall happy tone and the output is yes. So this is a positive example.

Now, solve this instance: Excuse me , I'm a little lost . Which bus do I take to get to Shi Da ? Let's see . From here , you have to take the 278 bus . Oh OK , where do I get off ? You should get off at the first Shi Da stop . Ok , thanks ... You're new at this , huh ? No , is it difficult ? No , it's quite simple . When you get on , just ask the bus driver when to pay the fare and where you want to get off . How much does it cost ? Only 15 NT per section . Oh look , that is your bus . Wow , I can't thank you enough . Don't mention it .
