Input: Consider Input: New York City bouncer Frank "Tony Lip" Vallelonga is searching for new employment while the Copacabana nightclub, where he works, is closed for renovations. He is invited to an interview with Doctor Don Shirley, an eccentric African American pianist who is looking for a driver for his eight-week concert tour through the Midwest and Deep South. 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.

Output: What is the last name of the person who was hired because of good references?

Input: Consider Input: A tree comes down in a forest and several lumberjacks hack away at it with their axes. To the side, two lumberjacks, one a muscular man, the other one rather scrawny, chop at a tree, but only the larger man makes any progress. The skinny fellow prances off to a tiny sapling and with some effort chops it down, only to end up with pieces of it stuck to his head. The pieces resemble antlers. The lumber men have several inventive methods for chopping trees: one, involving a tractor-like vehicle with a large saw protruding from its side, leads to the felling of a guard tower in the forest! The scene switches to Buddy, who, upon chopping a tree with his axe, sends such a shake upwards that a mother and father bird are forced to remove their nest and babies from the tree top and carry the nest elsewhere. Some time obviously passes, for in the next scene, Buddy has already succeeded in felling the trunk. Merrily whistling away, Our Hero next gently glides a lawnmower-like device across a fallen trunk, in the process creating many toothpicks, which he then dumps into a truck, yelling to the driver: "Take it away!" Using a saw as though it were a jump rope, Buddy cuts a standing tree into several smaller pieces. Buddy so goads a goat that the creature chases him. The goat's horns cut through the suspended logs atop which Buddy runs from the pursuing creature. Eventually, the goat rams headfirst into a tree, and gets incapacitated. Buddy then carries an armful of small logs, but drops them, upon tripping, just perfectly that they are arranged across a wooden stand as a xylophone, which Buddy then plays by means of two axes: a totem pole comes to life and dances for the lumberjacks. The hard-working men are called to supper: enthusiastically, they wash up. A song before the meal: "I Open the Old Northwest", with Buddy at the piano. Cookie serves the men their spaghetti.


Output: Who has a nest with babies in the tree that is chopped with an axe?
