answer: Jim bikes to work while #Person1# takes the train. Jim thinks both of the transportations are environmentally-friendly.
documents: #Person1#: Hey, Jim. I didn't know you biked to work.
  #Person2#: Yeah, it helps keep me fit and helps the environment, too.
  #Person1#: One less car on the road means less pollution.
  #Person2#: Right. Since my work is near a park, it's a really nice ride, too.
  #Person1#: How far is it?
  #Person2#: Oh, about 10 miles. It takes me about an hour.
  #Person1#: That doesn't sound too bad. I wish I could do it, but I work in the city. So I take the train.
  #Person2#: You're doing your part for the environment by using public transportation, too.
  #Person1#: True. Well, see you tomorrow.
  #Person2#: See you.
