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'.
One example is below.
Q: 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 !
A: informal
Rationale: 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
Q: Person1: Well , we've settled the problems of price , quality and quantity . What mode of payment do you wish to employ ?
Person2:Irrevocable letter of credit , of course . It's the normal terms of payment in international business .
Person1: Could you adopt D / A or D / P ? You see I have to pay a deposit when I open a letter of credit . That will tie up my funds and add to the cost of my imports , especially for such a huge order .
Person2:You might consult your bank and see if you could reduce the required deposit to a minimum .
Person1: Anyhow , there would be certain bank charges . We've done business for years and you should have some faith in our credit . It would help me greatly , if you could accept D / A or D / P . It makes no difference to you , but it does to me .
Person2:Well . As you understand , the irrevocable L / C gives the exports additional protection of the banker ' s guarantee . We always ask for L / C for our exports , and the other way around , we pay by L / C for our imports . We only accept L / C for regular orders .
