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: that was a great party . Thanks for saying behind to help me clear up .
Person2:it certainly was a great party . It ' s a pity that a glass and a plate got broken and someone spilled a drink over here .
Person1: I expected that something might get broken . That doesn ' t bother me . That spilled drink won ' t leave a stain , will it ?
Person2:I doubt it , I ' ll deal with it right away . Luckily it wasn ' t a glass of red wine , I ' ll just get a bowl of water and a cloth .
Person1: I ' m going to put all the rubbish into this big plastic bag .
Person2:afterwards , we can do the washing up together . Everything will be finished within an hour . Your friend Keith is really funny . I liked his magic tricks .
Person1: yes , he ' s very good .. isn ' t he ? He told some funny stories too .
Person2:Amanda told some very funny jokes . At the beginning of the party , she was being ver serious .
Person1: I think that she had a litter too much of the punch .
Person2:what did you put in that punch ? It tasted great , but was quite strong .
Person1: that ' s my little secret . Did you like the snacks and I prepared ?
Person2:very much . The birthday cake was delicious , wasn ' t it ? Emily told me that she and karen made it themselves .
Person1: that cake tasted so good ! It disappeared within minutes , so I think everyone liked it a lot . How ' s that stain ?
Person2:all cleaned up . Are you ready to start on the washing up .
