Passage: Sometime after 4 p.m. on December 6, 1989, Marc Lépine arrived at the building housing the École Polytechnique, an engineering school affiliated with the Université de Montréal, armed with a semi-automatic rifle and a hunting knife. Lépine purchased a rifle on November 21, 1989, in a Checkmate Sports store in Montreal. He had told the clerk that he was going to use it to hunt small game. Lépine had been in and around the École Polytechnique building at least seven times in the weeks leading up to December 6.
Lépine first sat in the office of the registrar on the second floor for a while. While there, he was seen rummaging through a plastic bag. He did not speak to anyone, even when a staff member asked if she could help him. Lépine left the office and was subsequently seen in other parts of the building before entering a second-floor mechanical engineering class of about sixty students at about 5:10 p.m. After approaching the student giving a presentation, he asked everyone to stop everything and ordered the women and men to opposite sides of the classroom. No one moved at first, believing it to be a joke until he fired a shot into the ceiling.Lépine then separated the nine women from the approximately fifty men and ordered the men to leave. He asked the remaining women whether they knew why they were there, and when one student replied "no," he answered: "I am fighting feminism." One of the students, Nathalie Provost, said, "Look, we are just women studying engineering, not necessarily feminists ready to march on the streets to shout we are against men, just students intent on leading a normal life." Lépine responded, "You're women, you're going to be engineers. You're all a bunch of feminists. I hate feminists." He then opened fire on the students from left to right, killing six, and wounding three others, including Provost.  Before leaving the room, he wrote the word shit twice on a student project.Lépine continued into the second-floor corridor and wounded three students before entering another room where he twice attempted to shoot a female student. When his weapon failed to fire, he entered the emergency staircase where he was seen reloading his gun. He returned to the room he had just left, but the students had locked the door; Lépine failed to unlock it with three shots fired into the door. Moving along the corridor, he shot at others, wounding one, before moving towards the financial services office where he shot and killed a woman through the window of the door she had just locked. 
Question: What is the first name of the person who sat in the office of the registrar on the second floor for a while?

Ex Output:
Marc.

Passage: At the New York Bulletin newspaper, its owner, Robert Drexel Gow, receives a teletype story that the newspaper's thirty-nine-year-old editor, Max Wharton, is resigning to enlist in the army. Robert is livid, both at the news and the method that he found out about the news. There is a second story on the teletype: Max's wife, the famous novelist Paula Wharton (whom Max calls Paulie), is in Hollywood adapting her latest book into a movie screenplay. Max wants to do his duty as a citizen and responsible journalist to be close to the war. Robert's view is that without Max, the newspaper will fold because Max *is* the newspaper.
From Hollywood, Paulie telephones Max and congratulates him on his decision. After Max informs her of the plan of basic training then possibly officer's candidate school, Paulie decides that she will move to where ever that school is to be close to him.
After completion of basic training, Max sends Paulie a telegram that officer's candidate school is in Tetley Field, Florida. She doesn't quite understand Max's motivations, but she wants to see her husband succeed in this passion.
Paulie arrives at Palmetto Court looking for bungalow 26D and meets the last tenant, Jan Lupton, whose husband Roy has just graduated to second lieutenant. Jan gives Paulie the lowdown on life in 26D, and that life for the enlisted at Tetley Field is all work, work, work. With school, Jan relays a story she heard where once you're over 21 years of age, your brain doesn't absorb the material taught anymore. Max comes by the bungalow surprised to see his wife there already. They have a loving reunion. The Luptons say goodbye to the Whartons, who can now have a proper reunion. 
Question: What is the full name of the wife of the man who graduated to second lieutenant?

Ex Output:
Jan Lupton.

Passage: 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. 
Question: What does Buddy play by means of 2 axes?

Ex Output:

xylophone.
