Question: 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: Four lifelong friends from the Boston neighborhood of Charlestown, Douglas "Doug" MacRay, James "Jem" Coughlin, Albert "Gloansy" MacGloan, and Desmond "Dez" Elden, rob a bank. They take the manager, Claire Keesey, hostage, but release her unharmed. When they find out Claire lives in their neighborhood, Doug begins to follow her to find out how much she has told the police, and to make sure that Jem does not eliminate her as a witness. Soon a romance grows between them, which Doug hides from the gang. As they grow closer, Doug tells Claire of his search for his long-lost mother, who he believes went to live with his aunt in Tangerine, Florida. He also recounts his chance to be a professional hockey player which he threw away for a life of crime, following in his father's footsteps. She in turn tells Doug that she saw a tattoo on one of the robbers, and he realizes that she can identify Jem and send them all to prison. He knows that Jem will kill her if he discovers the truth, so he persuades her that the authorities cannot protect her, and she decides not to tell the police.
After Claire tells Doug about being harassed and her car vandalized by Alex, a local Dominican thug, Doug enlists Jem for a favor, which they can never talk about. Doug and Jem don hockey masks and violently assault the offenders without Jem knowing the true reason for the favor is to protect Claire. 
Question: What are the aliases of the people who take a hostage?

Answer: Doug.


Question: Passage: American pressmen had been alerted to an upcoming Buddhist demonstration to coincide with Double Seven Day at Chanatareansey Pagoda in the north of Saigon. The nine-man group, which included Arnett, Browne, AP photographer Horst Faas, David Halberstam, Neil Sheehan of United Press International, and CBS's Peter Kalischer and photographer Joseph Masraf waited outside the building with their equipment. After an hour-long religious ceremony, the Buddhist monks, numbering around 300, filed out of the pagoda into a narrow alley along a side street, where they were blocked and ordered to stop by plain-clothed policemen. The Buddhists did not resist, but Arnett and Browne began taking photos of the confrontation. The police, who were loyal to Ngo Dinh Nhu, thereupon punched Arnett in the nose, knocked him to the ground, kicked him with their pointed-toe shoes, and broke his camera. Halberstam, who won a Pulitzer Prize for his coverage of the Buddhist crisis, was a tall man, standing around 20 centimetres (8 in) taller than the average Vietnamese policeman. He waded into the fracas swinging his arms, reportedly saying "Get back, get back, you sons of bitches, or I'll beat the shit out of you!" Nhu's men ran away without waiting for a Vietnamese translation, but not before Browne had clambered up a power pole and taken photos of Arnett's bloodied face. The police smashed Browne's camera, but his photographic film survived the impact. The other journalists were jostled and rocks were thrown at them. Photos of Arnett's bloodied face were circulated in US newspapers and caused further ill-feeling towards Diem's regime, with the images of the burning Thich Quang Duc on the front pages still fresh in the minds of the public. Halberstam's report estimated that the altercation lasted for around ten minutes and also admitted that the pressmen had tried to apprehend the policeman who had smashed Browne's camera but were shielded by the rock-wielding policeman's colleagues. He also claimed that the secret policemen had also tried to seize equipment from Masraf and Faas.
Diem's address on Double Seven Day worsened the mood of Vietnamese society. He stated that the "problems raised by the General Association of Buddhists have just been settled." He reinforced perceptions that he was out of touch by attributing any lingering problems to the "underground intervention of international red agents and Communist fellow travelers who in collusion with fascist ideologues disguised as democrats were surreptitiously seeking to revive and rekindle disunity at home while arousing public opinions against us abroad". The remark about fascists was seen as a reference to the conspiratorial Dai Viet Quoc Dan Dang who had long been enemies of Diem, but his address attacked all those who had criticised him in the past. He no longer trusted anyone outside his family and considered himself to be a martyr. 
Question: What two events were the American pressman alerted to that were going to coincide together?

Answer:
Buddhist demonstration.
