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: Are you ready to go the concert ?
Person2:Yes . Should we go there by bus so we aren't late ?
Person1: Actually , why don't we go there by bike ? We could get stuck in traffic if we travel by bus in rush hour .
Person2:That's true . Cycling is good for our environment , too . Let me just get my helmet then .
Person1: Is your helmet comfortable ?
Person2:Not really , but I liked the design , so I got it .
Person1: Maybe you should think about getting a round helmet ; they're better .
Person2:I'll think about it .
Person1: Is that your new bicycle ?
Person2:Yes , my father gave it to me for my birthday . Do you like it ?
Person1: It's the newest 10 speed cycling mountain bike . These are really expensive !
Person2:Nothing but the best from my dad . I like everything about it except for the brakes . They are a bit sticky .
Person1: I can fix those for you . Is there anything else wrong with it ?
Person2:Well , my saddle is too low for me . Do you know how to change the height ?
Person1: That's easy . It's important to have the saddle high enough so that your legs can extend fully when you are on your bicycle .
Person2:Is that why my knees have felt sore after every time I've ridden my bike ?
Person1: It's possible . Give me a minute and I can fix these for you and then we can go .
