Example Input: 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?
Example Output: Marc.

Example Input: Passage: Elliot Hopper is a workaholic widower who is about to land the deal of a lifetime at work, which he hopes will win him a promotion and a company car. After he forgets his daughter Diane's birthday, he attempts to make it up to her by promising her she can have his car when he secures the deal at work on the coming Thursday. After being persuaded to give the car to his daughter early, Elliot must hail a taxi from work, which is driven by Satanist Curtis Burch, who drives erratically and is of control. Attempting to get the taxi stopped, Elliot announces that he is Satan and commands him to stop the taxi, and also attempts to give him his wallet. Shocked to see his "Evil Master", Burch drives off a bridge and into the river.
Elliot emerges from the accident scene, only to learn that he is a ghost when a police officer fails to notice him and a speeding bus goes straight through him. When he gets home he discovers that his three children can see him, but only in a totally dark room, and they can't hear him at times. He struggles to tell them what happened when he is whisked away to London by paranormal researcher Sir Edith, who tells him he is a ghost who has yet to enter the afterlife because "they screwed up"; his soul will not cross over until Thursday.
The pressures of work and family life lead to many comedic events, as Elliot attempts to renew his life insurance policy and complete his company's merger, so his family will be provided for once he crosses over. One day, he must choose between staying in an important work meeting and helping his son with a magic trick at school. He eventually decides that his family's happiness is more important and walks out on his furious boss, Mr. Collins, who later smugly fires him. Dejected, Elliot reveals himself as a ghost to his love interest, Joan, whose initial shock soon turns to sympathy. 
Question: Who is Elliot Hopper's boss?
Example Output: Mr. Collins.

Example Input: Passage: Fifteen disparate African American men board a bus in Los Angeles bound for Washington, D.C., where they plan on attending the Million Man March. Other than their race, destination, and gender, the men have nothing in common: George is the trip organizer; Xavier is an aspiring filmmaker hoping to make a documentary of the March; Flip is the vain but charismatic and openly homophobic and sexist actor; Kyle and Randall are a homosexual couple; Gary, a biracial police officer; Jamal is a former gang banger turned devout Muslim who has evaded prosecution for the murders he committed; Evan Jr., is a petty criminal who has been permitted to break probation to attend the march on the condition that he remain handcuffed to his father, Evan Sr.
As the bus travels across country, Xavier conducts interviews with the various attendees, allowing them to express their views on race, religion, and politics. The interviews often provoke outbursts from other men on the bus, invariably leading to many political confrontations. Jeremiah, the eldest member of the group, is an 80-year-old former alcoholic who lost his job and family, has found new meaning in life and is energized by the Million Man March, and embraces his African heritage; his philosophies on the black experience and stories of precolonial Africa serve to unite the men and ease tensions and the infighting among them.
En route the bus breaks down and the men are forced to board another bus, driven by an ethnically Jewish white man named Rick. A couple of the passengers harass Rick as a white man, and Rick ultimately refuses to drive any further, citing the group's prejudice and his opposition to antisemitic remarks made by the leader of the march, Louis Farrakhan. George, himself a bus driver, accuses Rick of cultural racism, but begrudgingly agrees to cover for Rick who leaves. George takes over driving for the remainder of the trip, with help from Evan Sr. 
Question: What is the name of Evan Sr.'s son?
Example Output:
Evan Jr.
