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 last name of the person who did not speak to anyone when a staff member asked if they could help him?
answer:
Lépine.


question:
Passage: Hotshot ensign Alan Drake, fresh from the flying academy at Pensacola, Florida, gets off to a bad start with the pilots of an elite squadron, nicknamed the "Hellcats", to which he has been posted in San Diego. Making a nearly disastrous landing attempt in heavy fog against orders and disqualifying the squadron during a competitive shooting exercise by colliding with the target drogue does not endear him to his fellow pilots. He also asks out a woman he has met, Lorna, not knowing that she is the squadron commander Billy Gary's (Walter Pidgeon) wife.
However, Drake is earnest and contrite. He mixes with the Hellcats at the Garys' large house, which the sociable couple have opened as an unofficial officers' club. His flying and his social errors are forgiven, and his fellow pilots accept him, nicknaming him "Pensacola". 
Drake further proves himself when he helps Lieutenant Jerry Banning solve a problem in a blind-landing apparatus he is developing. Just after Commander Gary is sent out of town on assignment, Banning decides the apparatus is ready to test in fog — but it fails and Banning is killed. Working with Banning's assistant, Drake soon identifies the problem, but no further testing is allowed until Commander Gary's return.
Banning had been a childhood friend of Lorna Gary, and is not her first friend to die. She sinks into a deep depression. She also knows that Gary will expect her to hide her feelings and carry on, something that is very much not in her nature. Drake, appreciating the help the Garys gave him when he arrived, visits her at her home, and convinces her she should not suffer alone. They go for walks, drives, and tennis; he amuses her with jokes. Finally, at a restaurant she reaches for his hand and in doing so realizes she is falling for him. She quickly breaks away, and says she cannot see him any more. 
Question: What is the last name of the person that Lorna realizes that she can't see anymore?
answer:
Drake.


question:
Passage: Five men, criminals Ray, Dave, Stevie, Julian ("Julie" as a nickname), and Jason, plan a heist to steal a minimum of £2 million. Using a truck modified as a battering ram, the group break into a security depot in London and steal a large amount of money before the police arrive. However, they discover they barely got the amount of money they wanted, and only £68,000 to each man. Julian demands an extra amount of money as "expenses" for his work, but is beaten and placed in the boot of Ray's car until he just accepts his share. The group, without Julian, later spend time at a bar with fellow criminal Sonny, and Ray's girlfriend Connie, a protester. Ray and Stevie also visit an elderly couple, Linda and Bill, where they leave their stolen money for safekeeping.
The next day, Ray and Stevie, who live together with Connie, are alerted by a bruised Dave that his money was stolen, apparently by Julian. Ray, Dave and Stevie investigate Linda and Bill's home to find them murdered and the money stolen, leaving Ray emotionally distraught. He visits Julian but his money is missing too. They conclude that Sonny stole the money and break into his house, only to find Jason dead with a headwound. The four are alerted to a pair of undercover police officers and flee, Dave and Julian engaging in a shootout with the police. Believing that he may be arrested for murder, Ray decides to flee after the money is found, and goes to his mother and Connie for help. His mother gives him some money and her car to use, disappointed in her son's career but still caring for him. Ray then speaks with Connie and asks her to come with him, and to meet her at a roadside service station on the M1 if she decides to come. 
Question: Who tells the criminals that place their money with the elderly couple that the money is stolen?
answer:

Dave.
