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'.
Input:  Person1:       I've read your report , and I'm not sure I agree with you.You think you can get attendance improved by requiring salaried employees to take their all of their sick days ? 
 Person2:That's right . I know it must sound crazy to you , but we believe there will be fewer absences this way . 
 Person1:        We give them 10 or 15 sick days per year . Surely requiring people to take them couldn't possibly help . It sounds like a counter - productive policy change to me . 
 Person2:Right now , we have incentives encouraging employees to come to work as often as possible.But employees with colds and the flu are coming to work and infecting their colleagues . 
 Person1:        I see . So our current policies are encouraging sick people to come to work , resulting in more sick employees . 
 Person2:That's right . If sick days were mandatory , sick people would stay home . We wouldn't have these company-wide epidemics . 
 Person1:        Let's give it a shot !
