In the stimulus, Harry is stating that people can go around the world much more quickly than they used to be able to. Judith disagrees, as she says that many flights are too expensive for lots of people.
Harry is simply stating that going around the world is much faster now, and Judith is disagreeing with Harry's use of the word "anyone," as she is saying that not everyone can do this. Harry is saying it's physically possible for anyone to do it, but Judith is saying that it's not practically possible for anyone, which is how she was interpreting his claim.
We're asked with choosing the answer choice that correctly states how Judith was interpreting Harry's statement.
(E) says, "anyone can afford to travel long distances by air"
This is precisely how Judith was interpreting Harry's statement. She was interpreting the word "anyone" in a literal sense and to arguing that not anyone can do it because of cost. Harry was just saying that it's technically possible for anyone to do it.
