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?

Marc.

Passage: Richard "Dick" Purcell, a taxi driver, aspires to achieve his dream of becoming a singer. After a couple of theatre critics discover him while riding in his cab, one of them recommends him to a radio producer. The producer's secretary, Alice Hughes, hears him sing and falls in love with him. She sets up an audition for Dick to sing for the sponsor, Mrs. Flaggenheim. He's late for his audition and blows his big chance. 
Convinced she must go to Italy to find a good enough singer, with enough "romance" to represent her fine cheese products, Mrs. Flaggenheim takes Alice with her to find one in Venice. Dick watches as Alice boards the ship and manages to get on board and work for his passage to Italy. When in Venice, he looks up his friend and mentor from New York City, professor de Vinci, who had gone ahead to use his old connections to help Dick's singing career. They manage to score a couple of jobs as gondoliers for an upcoming event.
Dick uses the opportunity to showcase his voice. Mrs. Flaggenheim hears him and wants to sign him to a contract immediately, thinking he's an authentic Italian named "Ricardo Purcelli". Alice recognizes him, but they continue to hide his true identity and they all go back to New York, where he quickly becomes a radio sensation. Alice's jilted boyfriend finds out Ricardo Purcelli is actually just Dick and gives him an ultimatum. Dick must decide if he wants to continue masquerading as Ricardo and finally attain the fame and fortune he'd always dreamed of....or give it all up for Alice, the one he loves. 
Question: In order to be with the radio producer's secretary, who must he stop pretending to be?

Passage: Fed up with her dead-end job with a Minneapolis car rental agency, Martha quits, cashes her final paycheck, and uses the money to purchase an airline ticket to the least expensive international destination she can find - London. At the airport, she meets Daniel, a successful music label executive, who covertly arranges for her to be upgraded to First Class and seated next to him on the flight. When she sells the ticket to another passenger and Daniel finds his seatmate is an obnoxiously loud woman instead of the girl of his dreams, he moves back to the Economy section and takes the vacant seat next to Martha. Before landing in London, he offers her the use of a deluxe suite in a luxury hotel at his company's expense in exchange for a lunch date the following day.
Through a series of flashbacks and flashforwards, we learn Laurence, a former bridge champion who now teaches the game to wealthy women, went to the airport to pick up Daniel but missed him because the flight landed early. Instead, he literally runs into Martha, who hits him with a luggage cart while searching for the exit. She coerces him into taking her into the city and invites him to the suite for dinner. While she is in the bathroom, a bouquet of flowers from Daniel is delivered to the suite, and when Laurence sees the attached card, he departs without explanation.
The following day, Martha meets struggling actor Frank, who has fled an audition in a panic and has gone to the park to console himself with a half-bottle of whiskey. Having heard about her from Daniel, he realizes who she is and calls Laurence to boast that he is about to make her his conquest. He takes her to a nearby art gallery. Martha slips away and heads for the exit, where she reunites with Laurence, who was looking for the pair. He invites her back to his flat and she accepts. 
Question: What is the first name of the person who sells her ticket to a fellow passenger?

Ex Output:

Martha.
