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'.

Person1: I usually bowl with an eight ball . I like the control of a light ball . I can spin it more , so that the ball hooks .
Person2:Well . I like them a little heavier . I don't have as much control , usually bowling straight , but the extra momentum compensates for that .
Person1: Well , let's see which technique is better . I think I'll go up first ... Yes ! I hit a strike . I knocked them all down on my first bowl .
Person2:Well done . You got them all . You get 10 points and your next two bowls are added to this frame's score . I'II dry my ball off and try to knock them all down as well .
Person1: Good start . You knocked eight pins down . But you are left with a 7,10 split . Unless you can bowl a UFO-ball on this bowl , it is going to be impossible .
Person2:I certainly can try ... No ! It went straight through the wickets .

Person1: John , you have done a good job . Our new series computer is appreciated by the guests . They intend to sign contracts with our company . You really did a good job .
Person2:Thank you . I can't imagine the design of the new computer is so popular among computer users .
Person1: Hah , as the sale department director of our team , you are the best .
Person2:I am flattered . But I am not sure whether the manager is satisfied with it . She asked me to her office .
Person1: Why not ? You've done so well for the company . She should give you a prize .
Person2:I feel nervous when I face her . She looks so serious when we have a conversation all the time .
Person1: Come on ! What are you nervous about ?
Person2:It is said that the sales for the new computer did not meet the expectation .
Person1: But the sale number is close to the predicted amount .
Person2:I'm still nervous . I don't know what to say to the manager . I always feel ill at ease in that kind of place .
Person1: Take it easy . Be confident . I'm sure you can do it .
informal

Person1: Dou you think I should join a basketball team , Mary ?
Person2:Why not . If I were you , I certainly would .
Person1: But I'm afraid it will take too much of my time .
Person2:As the saying goes , work value work , play value play . All work and no play make a jucky-dull boy , you know .
Person1: Em , you ' re right .
