Q: I have an important test coming up. So, I've been studying a lot lately. I was studying at the library last night. I set aside four hours to study. But, half way through, my stomach started rumbling. I tried to keep my mind off of it, but my hunger was distracting me from my work. So, I decided to grab something from the vending machine. I stopped studying, and I want to the lounge area of the library. I was surprised by all the great options available. I could choose both hot and cold items. For example, there were tiny sandwiches which could be heated up in a nearby microwave. There were also ice cream sandwiches. I love those frozen treats. I decided, however, just to get some pretzels. I put some change into the vending machine. There were codes for each item available. I entered the code for pretzels into the computer on the side of the machine. And, my pretzels dropped into the bay at the bottom of the machine. I reached into the bay, and I pulled them out. I ate them quickly. They were delicious. I then returned to my homework.

A: Why did they decide to use the vending machine?

Q: New York City bouncer Frank "Tony Lip" Vallelonga is searching for new employment while the Copacabana nightclub, where he works, is closed for renovations.

Don hires Tony on the strength of his references. They embark with plans to return to New York on Christmas Eve. Don's record label gives Tony a copy of the Green Book, a guide for African-American travelers to find motels, restaurants, and filling stations that would serve them.They begin the tour in the Midwest before eventually heading farther south. Tony and Don initially clash as  Don is disgusted by Tony's habits while Tony feels uncomfortable being asked to act with more refinement. As the tour progresses, Tony is impressed with Don's talent on the piano, and increasingly appalled by the discriminatory treatment that Don receives from his hosts and the general public when he is not on stage. A group of white men threatens Don's life in a bar and Tony rescues him. He instructs Don not to go out without him for the rest of the tour.
