Q: 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 kind of music do you like listening to ?
Person2:I like music that has a fast beat and is lively , like dance music . You know , I go to a disco almost every week . Sometimes it ' s too loud though . You prefer classical music , don ' t you ?
Person1: yes , I do . I find it very relaxing . I often listen to Mozart or Bach in the evening after a hard day at work .
Person2:I must admit that I like several pieces of classical music . It ' s certainly more sophisticated that modern dance music .
Person1: classical music is supposed to be good for you brain . Research suggest that it makes your brain more active . Students who listen to classical music while studying perform better .
Person2:really ? Perhaps I should listen to classical music often . I heard that listening to classical music is helpful in reducing stress .
Person1: yes . That ' s why I listen to it in the evenings . I usually play it as background music while I ' m cooking or doing other housework .
Person2:I ' Ve got a few classical music CD ' s . I should follow your lead and increase my brain power .
Person1: you can find plenty of recording on the internet too . You can listen to samples and then buy them very cheaply if you like them .
Person2:that ' s a good idea . You should do the same with some music . You might find something you like . Classical music might make you clever , but dance might make you livelier and happier .
Person1: that ' s true . There ' s clear evidence that people who listen to lively music are lively people . Music can influence a person ' s feeling and character .
