documents: #Person1#: Car trouble center. How may I help you? 
  #Person2#: My car won't start! Stupid old car! 
  #Person1#: Hold on, before you kick your car let's go through some possible problems. 
  #Person2#: Fine. 
  #Person1#: OK, first of all, can you turn the key in the ignition? 
  #Person2#: Yeah! I am here with my friend and he thinks it may be the spark plug or the starter motor. 
  #Person1#: Those are possible problems, but tell me, when you turn the key, do you hear the starter motor crank? 
  #Person2#: Yeah, it sounds like it usually does when I start the car, but nothing else happens. The engine won't start. Should I maybe press the accelerator? 
  #Person1#: No. If you step on the accelerator pedal you can flood the carburetor and your car will never start. 
  #Person2#: So what do you think it is? 
  #Person1#: I know this may seem like a silly question, but does your car have gasoline? 
  #Person2#: Umm. yeah! Right! I got the car started! Thanks for your help! I told you to fill the tank!
