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'.

Let me give you an 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 !
The answer to this example can be: informal
Here is why: 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

OK. solve this:
Person1: Howdy ! Nice car ! What seems to be the problem ?
Person2:I don ' t know ! This stupid old car started spewing white smoke and it just died on me . Luckily , I managed to start it up and drive it here . What do you think it is ?
Person1: Not sure yet.How about you pop the hood and we can take a look . Mmmm , it doesn ' t look good .
Person2:What do you mean ? My daddy gave me this car for my birthday last month . It ' s brand new !
Person1: Well missy , the white smoke that you saw is steam from the radiator . You overheated your engine so now the pistons are busted and so is your transmission . You should have called us and we could have towed you over here when your car died .
Person2:Ugh ... So how long is this going to take ? An hour ?
Person1: I ' m afraid a bit more than that . We need to order the spare parts , take apart your electrical system , fuel pump and engine and then put it back together again . You are going to have to leave it here for at least two weeks .
Person2:What ! How am I supposed to get to school or go shopping ? This is not happening !
