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: how come you're still up ? Shouldn't you be asleep by now ?
Person2:I've been having a hard time sleeping lately .
Person1: as far as I know , insomnia is usually caused by stress . Are you stressed at all ?
Person2:well , I'm really worried about my grades . I didn't think this course would be so stressful .
Person1: you're a good student . I'm sure you can do well . What you need to do is to relax .
Person2:you're probably right . I just wish it were that simple . How can I stop feeling so anxious all the time ?
Person1: taking a yoga class or learning some relaxation techniques can help you cope with your stress .
Person2:I don't really have time to learn anything new . I need to spend my time studying !
Person1: you need to take some breaks throughout the day . Studying all day isn ' t very usually effective .
Person2:you ' re right . I usually end up starting at my computer or checking my email instead of doing my work for class .
Person1: besides , it ' s not difficult to learn yoga . In fact , I can teach you a move that ' s supposed to help you fall asleep ! You just have to sit down like this , bend over and breath in deeply .
Person2:that ' s fantastic . I ' m going to go try that out in my room now . good night !
Person1: good night , sleep tight ; don ' t let the bed bugs bite !
