Example Input: Person1: We've been cramming for tomorrow's history exam since early this morning . What do you say we take a break and listen to some music , okay ?
Person2: Now that you mention it , I'm getting a little bumed-out from studying nonstop , too . Listening to some music for a while would suit me just fine .
Person1: While you're picking out a record to play , I'll grab a couple of beers out of the refrigerator .
Person2: You sure have a lot of discs here .
Person1: Yeah , I've got everything from rock n ' roll to the latest new - wave stuff .
Person2: To tell you the truth , I'm strictly into classical music . You don't happen to have any Bach or Mozart , do you ?
Person1: Sorry , my taste in music doesn't go back any further than the 1960 ' s . Music written before then is just history to me .
Person2: Well , speaking of history , let's get back to the books.We ' Ve got an exam tomorrow , remember ?

Example Input: Person1: Wow , is that your sports car ?
Person2: Yes , do you like it ?
Person1: I love it ! I used to always want to drive a green jaguar . Is it in good condition ?
Person2: Yt looks good on the outside , but the inside is a different story . It needs a lot of servicing before it can go out on the roads again .
Person1: What's wrong with it ?
Person2: Well , first of all , it needs a new engine , which is extremely expensive .
Person1: When's the last time you had it serviced ?
Person2: It must have been a few years ago now .
Person1: I thought all cars needed regular servicing on a yearly basis .
Person2: They do . Once my son was born , there was no reason to drive this car anymore . It's only a two-seater , you know !
Person1: What else is wrong with it ?
Person2: The heating controls don't work anymore , so it always feels like it's about 100 degrees in the car even in the summer !
Person1: Anything else ?
Person2: The brakes don't really work that well anymore either .
Person1: Why don't you get it all fixed ?
Person2: It costs more than you think to run a car---especially when there are so many things wrong with it !
Person1: Well , let me know when you can get it fixed . I ' d love to go for a ride in it !
Example Output: 1

Example Input: Person1: Finally the class is over . Be quick . Ben must have been waiting for long .
Person2: Oh , I am so tired . My back is sore and my neck hurts .
Person1: That's normal . You have been sitting for three hours , with your attention highly concentrated .
Person2: You are wrong , Shirley . I was always absent-minded in the class . I meant to concentrate on the class , but I was just so tired . Maybe I am old .
Person1: No . You are just burning yourself out these days . Have a good rest and you will feel energetic again .
Person2: One of my friends took the Adult College Entrance Exam last year . He filled the school column with his name , and his score was relinquished .
Person1: How could he make such a silly mistake ?
Person2: He said he hadn't taken any exams for ten years , and couldn't get used to it immediately . He was extremely nervous then .
Person1: He lost a very good chance to go to college , didn't he ?
Person2: Yeah . The test was fairly easy and almost every test-taker could pass that exam . Adult College Entrance Exam is much easier than college entrance exam . And there are fewer subjects .
Person1: That's a very good lesson . We must familiarize ourselves with the exam from now on .
