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'.
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 ! 
Example solution: informal
Example explanation: 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

Problem:  Person1:       It ’ s so relaxing , taking a walk in the country . The air is so fresh and clean .  
 Person2:would you like to live in the country ? I ’ m not sure I ’ d like it .  
 Person1:        I can see a lot of advantage and disadvantage . The problem is that , for me , each advantage has its own disadvantage .  
 Person2:What do you mean ?  
 Person1:        Well , I hate the noise in the city , but I love being around lost of people . The problem is that you can ’ t have lots of people and have peace and quiet . The two just don ’ t go together .  
 Person2:I see what you mean . I love being far away from a city , but I hate being so far away department stores and sports facilities .  
 Person1:        People can ’ t have it both ways . If you live in the country , it is often less convenient . If you live in a city , it is noisy , but there ’ s more to do .  
 Person2:I would love to be surrounded by hills and streams . They ’ re so much better to look at than concrete , rows of parked cars and tall buildings .  
 Person1:        I would love to hear the birds singing and feel the fresh breeze on my face . When the wind blows in the city , you get dust in your mouth and in your eyes .  
 Person2:The view from the hill is so beautiful and relaxing . There ’ s so sign of pollution . The village looks so peaceful .  
 Person1:        Just remember that in that village there ’ s nothing to do . There ’ s not even a pub or restaurant . There ’ s just one small shop with a poor selection of goods .  
 Person2:You ’ re right . I would have to travel to the city at least once a week to go shopping and see friends . I would hate living in the country ! 

Solution: informal
