instruction:
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'.
question:
Person1: Are you excited about your trip next month ?
Person2:Yes and no . I can ' t wait to go to Europe , but at the same time I am terrified .
Person1: Why ?
Person2:Well , I have acrophobia . I have a chronic fear of flying .
Person1: Oh really ? I have an uncle who is also terrified of flying . It ' s not that bad though , I mean , it is pretty scary to be in this big machine flying through the air at seven hundred miles per hour . I actually have arachnophobia .
Person2:You ' re scared of spiders ? I actually have two more phobias . Acrophobia and glossophobia .
Person1: I guess that explains why you are afraid of flying , but public speaking is not that bad .
Person2:Are you kidding ? When I get on stage , my palms start to sweat , I get really nervous and I can hardly speak .
Person1: Well , I must confess I am a bit claustrophobic . I hate being in an elevator for more than 5 seconds .
Person2:We are such weirdos right ?
answer:
informal

question:
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 staring 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 !
