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: Hi . Can I help you with anything ? Yeah . Can I look at this ring ? Sure . Let me get it out for you . What is your size ? I believe I am a six . Here you go . Would you have any necklace that would go well with this ? Actually , we have a few to choose from . They are over here . There's no price tag on this necklace . Oh . I'm sorry . I'll check the price for you . It is $ 199 . This necklace is a little short . Do you have one that is longer ? Yes . Why don't you try this one on . This one is much better . Can I try on the ring with this necklace ? Sure . Here you go . Let me think about it . Sure . Take your time . Thank you for all the help . No problem at all .
