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'.

 Person1:       what kinds of tv programmes do you enjoy watching ?  
 Person2:I like current affairs programmes and documentaries , especially wildlife ones . How about you ?  
 Person1:        I like those kinds of programmes too . They ’ re very informative . I think that many people underrate the education value of tv .  
 Person2:I agree . People often criticize tv for showing too much sex and violence .  
 Person1:        yeah . And that ’ s so funny because most people prefer watching sex and violence to watching something more educational !  
 Person2:right . You can ’ t blame the tv stations for showing popular kinds of programmes . They need to make money from advertisements shown during and between programmes .  
 Person1:        in my country , there ’ s a time limit on the advertisements that can be shown . I think it ’ s about six minutes per hour .  
 Person2:that ’ s great idea . But don ’ t the tv station lose a lot of money because of that ?  
 Person1:        no . they don ’ t . they simply charge higher prices at peak times . Is there no limit on the amount of advertisements that can be shown on tv in your country ?  
 Person2:not as far as I know . We have so many advertisements . the interruptions are unbearable sometimes ! That ’ s one reason that many people prefer satellite or cable tv , where you pay a fixed amount each mo  
 Person1:        some people have satellite and cable tv in my country , but people don ’ t seem to keen to pay for their tv programmes . Besides , the terrestrial channels offer a good range of programmes .  
 Person2:well , there ’ s a wildlife documentary on tv in a few minutes . Shall we ?

 Person1:       Let's see if we forget anything .

 Person2:All right .
