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: Finally the class is over . Be quick . Ben must have been waiting for long .
Person2:Oh , I am so tired . My back is sore and my neck hurts .
Person1: That's normal . You have been sitting for three hours , with your attention highly concentrated .
Person2:You are wrong , Shirley . I was always absent-minded in the class . I meant to concentrate on the class , but I was just so tired . Maybe I am old .
Person1: No . You are just burning yourself out these days . Have a good rest and you will feel energetic again .
Person2:One of my friends took the Adult College Entrance Exam last year . He filled the school column with his name , and his score was relinquished .
Person1: How could he make such a silly mistake ?
Person2:He said he hadn't taken any exams for ten years , and couldn't get used to it immediately . He was extremely nervous then .
Person1: He lost a very good chance to go to college , didn't he ?
Person2:Yeah . The test was fairly easy and almost every test-taker could pass that exam . Adult College Entrance Exam is much easier than college entrance exam . And there are fewer subjects .
Person1: That's a very good lesson . We must familiarize ourselves with the exam from now on .
