TASK DEFINITION: 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'.
PROBLEM: Person1: Who stands out in your mind as a man or woman of sound character ?
Person2:If I think of famous people , I think of Abraham Lincoln .
Person1: He's the US president , who walked five miles just to give a lady her change , isn't he ?
Person2:That's the one . He also was famous for never giving up on his goals .
Person1: That's right . He ran for office quite a few times before he was finally elected .
Person2:And I also admire him for his courage in fighting for equal rights .
Person1: He had great vision , didn't he ?
Person2:And humility . I would have liked to meet him personally .

SOLUTION: informal

PROBLEM: Person1: Why are you so late ?
Person2:I've been through a lot today . I forgot to set my alarm clock last night , so I woke up late this morning . And what is worse , I missed the school bus .
Person1: That's enough . Sit down .

SOLUTION: informal

PROBLEM: Person1: How can I lose weight , doctor ? I seem to get fatter even when I just look at food ?
Person2:Well , Jim . It is a combination of how much you eat , the type of food you eat , and when you eat your meals .
Person1: I never eat breakfast though .
Person2:That's a big mistake , you should always have a good breakfast . You will not run your car without fuel , and as well you won't expect your body to work without food .
Person1: I never thought about it that way .
Person2:I bet you eat a large evening meal , then sit and watch TV or read a book . Then instead of burning off your energy , your body stores it as fat .
Person1: Oh doctor , I feel so foolish .
Person2:Well control is really using common sense when you plan your eating habits .
Person1: I know doctor , thank you so much .
