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:       are you ready for the meeting ?  
 Person2:yes , come on in . how's your new job going ?  
 Person1:        it's challenging , but I'm enjoying it quite a bit .  
 Person2:that's great . I knew you'd do a good job as a manager .  
 Person1:        thanks a lot .  
 Person2:how's your assistant manager getting on ?  
 Person1:        well , that's part of the problem . His probation period is up tomorrow and I don't think he's ready to pass .  
 Person2:what seems to be the problem ?  
 Person1:        well , he was supposed to be able to learn his job in 30 days , but he just doesn't seem to know what he's doing .  
 Person2:if you gave him another 30 days , do you think he could figure it out by then ?  
 Person1:        to be honest , he has no authority . He's a hard-worker , but no one listens to him .  
 Person2:I see . Not everyone is cut out to work in management .  
 Person1:        I know . It'd be great if we could transfer him to a department where he doesn't have to work with people .  
 Person2:there's an opening in the creative design department . It involves working with computers .  
 Person1:        that's perfect . I'll let him know tomorrow . Thanks !
