In this task, you're given a context passage. Your job is to generate relevant questions that can be answered by directly referring to the passage.

The novel takes place in a world where online "tribes" form, where all members set their circadian rhythms to the same time zone even though members may be physically located throughout the world. The protagonist, Art Berry, has been sent to an insane asylum as a result of a complex conspiracy. Told mostly in flashbacks, Art explains that he works in London as a consultant for the Greenwich 0 tribe. In reality, though, both he and his associate Fede are in fact double-agents for the Eastern Standard Tribe. Despite his talents as a human experience engineer, Art delivers subtly flawed proposals to the GMT tribe in order to undermine them and enable his own tribe to get a coveted contract. He meets a girl, Linda, after he hits her with his car at 3am. Art has an idea for peer-to-peer music sharing between automobiles, and plans to give it to the EST (taking a cut to himself.) However, his girlfriend meets his coworker, Fede, and they plan to double cross the EST and sell the idea to another tribe. Knowing Art won't approve of the plan, they do it behind his back. Fede later claims he would have cut Art in on the deal afterwards. However, Art figures out what is going on, and as a result they have him committed to an insane asylum to protect their plot. The book alternates between two points of view: Art meeting Linda in London, and Art in the asylum. The London plot culminates in his attack on Fede when he discovers his betrayal. The asylum plot takes place after his attack on Fede, and culminates in his escape from the asylum and founding of a new company to market health care products using his inside knowledge of psychiatric institutions.
Why is Art committed to the insane asylum?

After my workout today I wanted to get a snacked to keep my energy up; so I decided to go to the row of vending machines that the gym keeps outside the locker rooms. It's usually a hard decision when I get there, there is so many choices of healthy snacks. I searched the rows of energy bars and veggie snacks to find what would give me the biggest boost after my exercise. I made my choice and reached for the change in my bag so I could pay for my taste treat. I put my coins into the slot in the machine until I had enough to buy my snack. I punched in the number of my selection so the machine could do its work. The coil started to spin until my energy bar fell from its slot. I pushed through the flap to retrieve my bar and started to eat.

Why did they want to get something out of the vending machine?
