Teacher: You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues. You are required to assign a label 'formal' if there is an absence of emotion and a presence of questions anywhere within the conversation. If such pattern is not found assign the label 'informal'.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Person1: Hey man , you wanna buy some weed ?
Person2:Some what ?
Person 1:Weed ! You know ? Pot , Ganja , Mary Jane some chronic !
Person2: Oh , umm , no thanks .
Person1: I also have blow if you prefer to do a few lines .
Person2: No , I am ok , really .
Person1: Come on man ! I even got dope and acid ! Try some !
Person2: Do you really have all of these drugs ? Where do you get them from ?
Person1: I got my connections ! Just tell me what you want and I ' ll even give you one ounce for free .
Person2: Sounds good ! Let ' s see , I want .
Person1: Yeah ?
Person2:I want you to put your hands behind your head ! You are under arrest !
Solution: informal
Reason: Based on the conversation, we can see that there is a presence of exclamation which is not present in a formal discussion. Therefore this is an informal conversation

Now, solve this instance: Person1: I can't wait until my car is repaired . The commuting with public transportation is killing me .
Person2:It can't be that bad .
Person1: But it is ! Take this morning for example . The subway was so packed this morning , I got totally squished by about a hundred busy commuters on the way to work .
Person2:At least the subway is better than the bus . It's faster for one thing . And usually less crowded . But the drawback is that the subway is more expensive than the bus . It adds up over time , if you take it every day .
Person1: That's true . The bus is even worse . Just thinking about taking the bus every day makes me tired ! Hey , how do you get to work every day ?
Person2:I ride my bike . I don't live too far away , so it's pretty convenient . it's only about a ten minute bike ride from my house to the office .
Person1: I'll bet it's good exercise , too ... a good way to keep fit .
Person2:Yes , not only a good way to keep in shape , but a good way to relieve stress as well . While you're stressed out by your commute , I'm releasing all the stress of the day with mine .
