answer: Tom wanted to show #Person2# a cabin, but their car got stuck in a ditch and they are stranded in the snowstorm. #Person2# suggests saving the car's energy to conserve the heat as long as possible so that they can survive.
documents: #Person1#: What are we going to do? I can't get the car out of this ditch. I'm stuck!
  #Person2#: I'm worried, Tom. I haven't seen any other cars for almost an hour.
  #Person1#: I know. This is terrible. What can we do? This snow doesn't stop falling!
  #Person2#: I told you we should have stayed in town today.The weather report said 100 percent chance of snow.Why did you want to come up here?
  #Person1#: I wanted to show you the cabin. We only had another half-hour to go.
  #Person2#: Well, now we're stuck. What can we do?
  #Person1#: I don't know.
  #Person2#: I've heard that when this happens, it's important to save energy.
  #Person1#: What do you mean?
  #Person2#: We're stranded here, Tom. We may be here a long time.We need to conserve the gas in the car. The car's energy is what will keep us warm.
  #Person1#: I have plenty of gas.
  #Person2#: Yes, but the gas and the battery both have to stay working.We can't just let the car run and run.If we do, it will die soon. Then we'll freeze.
  #Person1#: So what can we do?
  #Person2#: Turn the lights off.Then, run the car and the heater only about fifteen minutes every hour.That will conserve the heat as long as possible.
  #Person1#: Alright. That's a good idea.
  #Person2#: I wish we hadn't come up here. Now we'll probably be here for days.
  #Person1#: Days?
  #Person2#: Yes, it happens.That is what happens in big snowstorms. People get stranded for days.
  #Person1#: Oh, my God! It's good we have food.
  #Person2#: Probably we'll survive.But turn the car off for about forty-five minutes. Then we'll turn it on again.
