Question

What are the authors' answers to the three questions in b? Are you convinced by their arguments?

Answer

  1. No, it can't.
  2. Probably nothing, although some flyers might worry more about security.
  3. Not necessarily, as it can be unclear what is actually a rule and what isn't, so people are unsure how to behave.
