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'.

[Q]: Person1: Hey , Jordan , is that you ? Long time no see !
Person2:Oh , hey , no kidding ! I haven't seen you since orientation three months ago ! So how've you been ? Settling into college life OK ?
Person1: Yeah , I think so ! I pledged Phi Iota Alpha , so I'm living at the frat house now .
Person2:Oh , so you're a frat boy now , huh ?
Person1: Yeah , yeah , I know , it's totally cliche , but really , I think it's been a good decision . I've got a lot of support and good suggestions from the guys . What about you ? What have you been up to ?
Person2:Not much . I'm still living at home and commuting to school . I ended up dropping that metalworking class I was so excited about . It just wasn't as interesting as I'd hoped . The guidance counselor suggested that I focus on my prerequisite courses so that I can make sure the credits count .
Person1: That sounds smart ... but kind of boring .
Person2:Yeah , it is , a little bit . I joined the Great Outdoors Club , though , which has been a lot of fun . We've gone on two camping trips already , and I've made some good friends .
Person1: That's cool . Hey , so have you decided on your major yet ?
Person2:Definitely pre-med . What about you ?
Person1: I still have no clue ... but we don't have to declare a major till our sophomore year , so I've got time ! Oops , I'm late for class . Gotta run !
Person2:OK , take care ! Hey , nice running into you !
Person1: Yeah , you too !

[A]: informal

[Q]: Person1: How is your house hunting going ?
Person2:Not very well . I haven ' t found anything within my price range yet .
Person1: How much are you looking to spend ?
Person2:I can only afford about 300 pounds a month .
Person1: Looks like you ' re not going to get more than a bedroom in a shared flat with that .
Person2:Really ? That ' s a lot of money to pay for one room .
Person1: Well , if you want to live in London , you have to pay the price !
Person2:Do you know of anyone who needs a roommate ?
Person1: I can ask around at work . Do you have a preference for makers or non-smokers ?
Person2:I ' d prefer non-smoking roommates , but I guess I ' ll have to take what I can get !
Person1: How long do you want to sign a contract for ?
Person2:I can sign a contract up to a year . I don ' t know where I ' ll be after that .
Person1: Do you need a furnished or unfurnished apartment ?
Person2:I don ' t have any furniture , so it ' d be great if it were furnished .
Person1: You know that you ' ll have to pay utilities on top of the rent , right ?
Person2:No , I thought that would be included in the rent .
Person1: It ' s not usually included , so you ' ll have to factor in about 100 pounds more each month for utilities .
Person2:I don't think I can afford that .
Person1: Don ' t worry . Sometimes people will give you a discount if you promise to do the cleaning or take care of the children .
Person2:That ' s a good idea . I ' ll look into finding something like that .
