documents: #Person1#: I'd like to know something about transport in Britain.
  #Person2#: Well, we have got the railways connecting all our big towns. There are over 13,000 miles of track in Britain. Rail transport provides a very important service.
  #Person1#: What about road transport? Are your roads very good?
  #Person2#: Yes, they are on the whole. We've got about a quarter of a million miles of roads, and modern motorways appearing everywhere. We should have over a thousand miles of motorways soon.

  #Person2#: Well, yes. But it is not as important as our rail and road transport systems.

  #Person1#: But I suppose today sea travel has become less important, hasn't it?
  #Person2#: It has. But some people still prefer traveling by sea to any other form of transport.
