In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: In 1932, a luxury yacht is sailing through a channel off the western coast of South America. The captain is worried about the channel lights not matching the charts, but is quickly dissuaded from changing course by the wealthy passengers for the sake of time, including famous big game hunter and author Bob Rainsford. It is a calm evening, with the cheerful passengers relaxing over drinks and a game of cards. Bob and his companions are debating about whether hunting is at all sporting for the animal being hunted after a friend asks if he would exchange places with a tiger he had recently hunted in Africa. Bob replies that there are two kinds of people in the world: those who hunt and those who are hunted.
The ship suddenly runs aground, causing the ship to take on water and heave violently. Water floods the boiler room, causing the ship to explode and sink into the channel. Rainsford and two others manage to get away and cling to wreckage, but the other survivors are eaten by a shark. He swims to a small, lush island. Wandering through the jungle, he sees the channel lights off the shoreline change, and suspects the ship was deliberately led off course to its doom.
He stumbles across a luxury chateau where he becomes the guest of the expatriate Russian Count Zaroff, a fellow hunting enthusiast. Zaroff remarks that Rainsford's misfortune is not uncommon; in fact, four people from the previous sinking are still staying with him: Eve Trowbridge, her brother Martin, and two sailors.
That night, Zaroff introduces Rainsford to the Trowbridges and reveals his obsession with hunting. During one of his hunts, a Cape buffalo inflicted a head wound on him. He eventually became bored with the sport, to his great consternation, until he discovered "the most dangerous game" on his island. Rainsford asks if he means tigers, but Zaroff denies it.

Ex Output:
What is the last name of the person who becomes a guest at a luxury chateau?

Passage: The blacksmith and swordsmith John is tutored at the court of King Arthur, but as a commoner he can't hope to win the hand of Lady Linet, daughter of the Earl of Yeonil. The Earl's castle is attacked by Saracens and Cornishmen disguised as Vikings and his wife is killed, making him lose his memory. The attack was part of a plot by the Saracen Sir Palamides and the pagan Cornish King Mark to overthrow Arthur and Christianity and take over the country, whilst pretending to be Arthur's friends and allies - Palamides is a knight of the round table and Mark has faked his own baptism.John accuses Palamides' servant Bernard of murder before Arthur, who grants him three months' grace to prove the accusation or face execution himself. Another knight, Sir Ontzlake, takes pity on John and trains him in swordplay so that he can take on an alternative secret identity as the wandering Black Knight. The "Vikings" raid a newly founded monastery and take Lady Linet and its monks to Stonehenge for a pagan sacrifice, but the Black Knight arrives and saves her, closely followed by Arthur and his knights, who defeat the pagans and destroy Stonehenge.
Sir Palamides tricks the Lady Linet into his castle to try to get her to reveal the Black Knight's identity, but John is informed of this and saves her, still in disguise. Sir Ontzlake then sends him to King Mark's castle, where a pro-Arthur woodcarver shows him a secret tunnel into the royal chambers. John arrives in time to overhear Mark and Palamides finalising their plot but Palamides beats him back to Camelot, tricking Arthur into thinking that the Black Knight is leading the Viking raids. John arrives dressed as the Black Knight and despite revealing his identity is briefly imprisoned until Lady Linet and Sir Ontzlake free him, with the latter standing bail for John to Arthur.

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.
