[|Human|] Why do people purchase ski passes?
[|AI|] People buy ski passes so that they have unlimited access to a mountain resort. If they visit the resort enough times in a season, they can save money by using a pass rather than buying individual tickets for each day. Also, using a pass makes it faster to enter the resort without having to stop at a ticket counter.
