Travel
Buy a ticket / which train?
Buy a ticket and ask which train or bus to take.
What makes this one hard
Ticket type, platform, transfers — all decided under time pressure with a train leaving. The hard part is not the question but the answer: directions given fast, by someone who says them all day, with one chance to catch the platform number.
