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: Man , they take a lot of our paycheck .
Person2:Yeah , the government really takes a bit , doesn't it ?
Person1: Seriously . The only tax I don't mind them taking is social security . It's only a few dollars every paycheck .
Person2:Yeah , I don't mind it either . We ' ll both end up rich slobs and not need it , but what if we do , you know ?
Person1: Yeah . It won't be much , but at least we ' ll have a monthly check when we get old .
Person2:Yeah , my grandmother gets by on social security and the money my grandfather invested when he was alive .
Person1: Let's just hope the politicians don't figure out a way to spend it .
Person2:Really ? No , they couldn't . None of them would have jobs if they did .
