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'.

Question: Person1: Are you excited about your trip next month ?
Person2:Yes and no . I can ' t wait to go to Europe , but at the same time I am terrified .
Person1: Why ?
Person2:Well , I have acrophobia . I have a chronic fear of flying .
Person1: Oh really ? I have an uncle who is also terrified of flying . It ' s not that bad though , I mean , it is pretty scary to be in this big machine flying through the air at seven hundred miles per hour . I actually have arachnophobia .
Person2:You ' re scared of spiders ? I actually have two more phobias . Acrophobia and glossophobia .
Person1: I guess that explains why you are afraid of flying , but public speaking is not that bad .
Person2:Are you kidding ? When I get on stage , my palms start to sweat , I get really nervous and I can hardly speak .
Person1: Well , I must confess I am a bit claustrophobic . I hate being in an elevator for more than 5 seconds .
Person2:We are such weirdos right ?

Question: Person1: Did you hear the news ? Two of our major suppliers , Murphy Music and U-Tunes are merging ! If they are conglomerated into one company into one company , it would have some serious affects on our market strategy .
Person2:Are you sure ? Who told you that ? I highly doubt that they would take the step to merge into one company ... They're supposed to be bitter enemies , the strictest of competitors.It must be a rumor.It can't be true .
Person1: I read it myself on the financial page.They ' re really going to join together . U-Tunes was bought out by Murphy's , they will take over the company as of next month .
Person2:The competition must have been too stiff for U-Tunes.Otherwise why would they allow themselves to be taken over by their sworn enemy ?
Person1: I guess they must have figured it would be easier to merge than to keep up the cutthroat competition.If you can't beat'em , join'em .
