[EX Q]: Passage: Sometime after 4 p.m. on December 6, 1989, Marc Lepine arrived at the building housing the Ecole Polytechnique, an engineering school affiliated with the Universite de Montreal, armed with a semi-automatic rifle and a hunting knife. Lepine 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. Lepine had been in and around the Ecole Polytechnique building at least seven times in the weeks leading up to December 6.
Lepine 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. Lepine 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.Lepine 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." Lepine 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.Lepine 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; Lepine 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 last name of the person who did not speak to anyone when a staff member asked if they could help him?
[EX A]: Lepine.

[EX Q]: Passage: In the town of Red Rock, gun salesman Steve Farrell demonstrates the new Colt .45 repeating pistols to the sheriff who is impressed that the United States government just ordered two thousand of these powerful weapons for the army. The demonstration is interrupted when men arrive to transfer one of the prisoners to another jail. As he's being led away, prisoner Jason Brett grabs the pistols, shoots the sheriff, and escapes, pretending that Farrell was his partner. Convinced that Farrell was involved in the escape, the townspeople arrest the innocent gun salesman. In the coming days, Brett initiates a campaign of robberies and cold blooded murder, with regular guns being no match for his Colt .45 pistols.
Four months later, Farrell is released from jail due to a lack of evidence. The new sheriff offers him a letter clearing him of the charges if he reveals Brett's whereabouts. Reasserting his innocence, Farrell vows to go after Brett to retrieve his guns. Farrell tracks his prey into Texas and comes across a band of Indians whom Brett has killed to provide cover for a stagecoach robbery. The only survivor of the attack, Walking Bear, tells Steve about Brett's plan. As the stagecoach approaches, Steve jumps onto the stage from a rock outcropping just in time to fight off the attack by Brett's gang with his own set of Colt .45s. The only passenger on the stage, Beth Donovan, tries to prevent him from fighting off the robbers.
Question: Who uses the gun salesman?
[EX A]: Jason Brett.

[EX Q]: Passage: Soon after the US enters World War II, Steve Britt, a former World War I flying ace, arrives at Thunderbird Field, looking for a job as a civilian primary flight instructor. The base commander is an old friend, Lt. Col. "Mac" MacDonald, working with Squadron Leader Barrett (Reginald Denny, himself a World War I aerial observer), who is in charge of the Royal Air Force cadets at the base.
Steve says he wants the job because he is too old for combat and the war will be won by pilots trained on bases like Thunderbird, but it is soon clear that he chose this base because his former girlfriend, Kay Saunders, lives nearby with her grandfather, retired Colonel Cyrus "Gramps" Saunders, also a close friend of Steve's.
Steve immediately flies to their ranch and performs stunts over a water tank where Kay is bathing, blowing her robe away and then dropping her his flying coveralls. When he lands, she seems miffed, but responds to his passionate kiss of greeting. Kay is still very fond of him, but no longer deeply in love.
Steve is introduced to the new class of RAF cadets, including Peter Stackhouse, whose father Steve knew. Mac warns Steve to "wash them out fast" if cadets cannot meet the requirements. Peter flies clumsily and is sick from acrophobia. After three such failures, Steve tries to persuade Peter to transfer, but Peter is confident he can overcome what he calls his "conditional reflex", and asks for more time.
Question: Who seems miffed by the flyover?
[EX A]:
Kay.
