In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

[EX Q]: 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?
[EX A]: Marc.

[EX Q]: Passage: After their HIV positive mother's death, Derick and Margaret collect wood and construct a human-length box with wheels. Then, they journey with it from Kampala to Kasangombe in a heartbreaking bid to overcome poverty and experience hope. The journey throws them dangerous experiences on unpredictable Ugandan roads. Their mother's dying wish had set them off on a seemingly impossible journey to find a relative they do not even know.
Before her death, she leaves them an envelope addressed to her sister (their auntie) who is married to a hard-working man living in a distant village called Kasangombe with their kids. Ingeniously, Derick creates a coffin using wood he collected from a rubbish dump and adds luggage bag rollers brought by Margaret. On their journey from Kampala City to their aunt's place, they are offered a lift by a seemingly kind man (played by Joel Okuyo Atiku) in a truck who is amazed by their "box". He introduces them to a kid he had taken under his wings relaxing at the back and shows them a photo of a house they can possess if they work for him. At night though, Margaret sees a scary dream where their helper is not exactly as kind as he seemed so she runs out of the truck. Derick follows and the boy throws out their coffin before waving. They walk the rest of the distance.
Initially, their uncle (played by Isaac Muwawu) did not want them in his house because he thought they were HIV-infected. Derick overheard him quarrel with his aunt at night and shook Margaret in the morning from another dream (this time beautiful, where both siblings were smiling and enjoying a picnic in a glorious garden with their aunt, uncle, cousins, dead parents and some whites). Derick convinced her to walk away from the home with him but without a reason. 
Question: How do the pair of siblings finish the last leg of their journey?
[EX A]: They walk.

[EX Q]: Passage: The French playwright Victorien Sardou wrote more than 70 plays, almost all of them successful, and none of them performed today. In the early 1880s Sardou began a collaboration with actress Sarah Bernhardt, whom he provided with a series of historical melodramas. His third Bernhardt play, La Tosca, which premiered in Paris on 24 November 1887, and in which she starred throughout Europe, was an outstanding success, with more than 3,000 performances in France alone.Puccini had seen La Tosca at least twice, in Milan and Turin. On 7 May 1889 he wrote to his publisher, Giulio Ricordi, begging him to get Sardou's permission for the work to be made into an opera: "I see in this Tosca the opera I need, with no overblown proportions, no elaborate spectacle, nor will it call for the usual excessive amount of music."Ricordi sent his agent in Paris, Emanuele Muzio, to negotiate with Sardou, who preferred that his play be adapted by a French composer. He complained about the reception La Tosca had received in Italy, particularly in Milan, and warned that other composers were interested in the piece. Nonetheless, Ricordi reached terms with Sardou and assigned the librettist Luigi Illica to write a scenario for an adaptation.In 1891, Illica advised Puccini against the project, most likely because he felt the play could not be successfully adapted to a musical form. When Sardou expressed his unease at entrusting his most successful work to a relatively new composer whose music he did not like, Puccini took offence. He withdrew from the agreement, which Ricordi then assigned to the composer Alberto Franchetti.  Illica wrote a libretto for Franchetti, who was never at ease with the assignment.
When Puccini once again became interested in Tosca, Ricordi was able to get Franchetti to surrender the rights so he could recommission Puccini.  One story relates that Ricordi convinced Franchetti that the work was too violent to be successfully staged. A Franchetti family tradition holds that Franchetti gave the work back as a grand gesture, saying, "He has more talent than I do." American scholar Deborah Burton contends that Franchetti gave it up simply because he saw little merit in it and could not feel the music in the play. Whatever the reason, Franchetti surrendered the rights in May 1895, and in August Puccini signed a contract to resume control of the project. 
Question: What is the last name of the person who complained about the reception La Tosca had received in Italy?
[EX A]:
Sardou.
