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: What are you reading about in that science magazine ?
Person2:There are several interesting articles on recent scientific breakthroughs . I just finished reading one about cloning .
Person1: I ' m not sure I like the idea of that . I don ' t want people copying me or other people . It could be very confusing .
Person2:According to the article , you have no real need to worry . Research nowadays is focussing on cloning parts of a human body to replace damaged or lost parts , not on recreating a whole human .
Person1: In the future , that could be possible .
Person2:In this article , scientists say that if you took the genes from someone and tried to create a copy of a person , there ' s no guarantee that the copy would look or act like the original !
Person1: Really ? What else have you discovered ?
Person2:I read about how scientists are using material from plants and animals to create new medicines . For example , an animal be immune to disease that affects human . So , scientists find out why it ' s immune
Person1: That ' s great , because it uses natural materials rather than ones that scientists make themselves . I prefer natural remedies to man-made ones .
