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.

Q: Passage: Two days after the events of the first film, a traumatized and blood-covered Sarah escapes the cave with no memory of the events. She is taken to a hospital, where it is found that some of the blood on her belongs to Juno Kaplan. Sheriff Vaines takes his deputy Elen Rios, Sarah, and three spelunking specialists Dan, Greg, and Cath to the cave to find the missing women. The team members are sent down via an old mine shaft operated by the old, mysterious Ed Oswald.
The group discovers Rebecca's mutilated body, causing Sarah to have flashbacks of the crawlers and causing Vaines to believe Sarah may be responsible for the girls' disappearance. While crawling through a tunnel, she attacks Vaines and the others, causing the others to split up. Vaines runs to search for Sarah, and in the process is surprised by a crawler, and fires his gun in a panic, causing a minor collapse in the cavern which traps Cath, separating her from Rios, Dan, and Greg. The three decide to find an alternate way around in order to try to free Cath and arrive in a room full of bones, where they find Holly's video camera. They watch it and realize the women were attacked by the crawlers. The three are then themselves attacked by crawlers and separated.
Rios starts calling for help, alerting the crawlers to her location, but is rescued by Sarah. The two then watch as a crawler kills Dan and drags his body away, prompting Sarah to inform Rios that the crawlers are blind and hunt via sound. After escaping from and killing a crawler, Cath finds Greg before the two escape from another crawler and find Sam's body. They decide to try to use her to swing across a chasm, but are attacked again. Greg sacrifices himself to buy time for Cath, but she ultimately does not survive.

A: Who attacks someone, causing the group to split up?

Q: Passage: Nathan Ellis, a 9-year-old maths prodigy, has just lost his father in a car accident. Nathan is diagnosed with autism early in the film, and his father was the only one who was able to connect normally with him. Although Nathan values his mother, Julie, he shuns any physical contact with her and treats her as more of a caretaker than a parent. Wanting to make sure Nathan isn't distracted from his studies, Julie enrolls him in advanced classes at a new school. There, he comes under the tutelage of teacher Martin, also a math genius, who now suffers from multiple sclerosis. Martin sees himself in Nathan, once a promising young mind in the field of mathematics, who gave it all up once he was diagnosed with his illness.
Seven years later, Martin is preparing Nathan to compete for a place in the International Mathematical Olympiad, a prestigious high school competition consisting of the world's best young mathematicians. This year, it is to be held at Cambridge, after a two-week math camp in Taiwan where the students will study for the test that determines the winners. Nathan fears he's not good enough to qualify but ends up doing well enough to accompany 15 other British teenagers to Taiwan.
Suddenly thrust out of his comfort zone, Nathan finds himself no longer the smartest math whiz in the room, and his social anxieties nearly paralyze his performance. He has trouble reading the social cues of others and flinches at the slightest physical contact with another person. Nathan is paired with a female Chinese student, Zhang Mei, who slowly helps him adjust to his new surroundings and helps him fight through his fears. By the skin of their teeth, Nathan and Zhang make the cut to compete in Cambridge.

A: Who comes under the tutelage of a math genius teacher?

Q: Passage: Chicagoan Chester "Chet" Ripley, his wife, Connie, and their two sons, Buckley "Buck" and Ben, are on vacation at a lake resort in Pechoggin, Wisconsin during the summer. All is going as planned until Connie's sister, Kate, her investment broker husband, Roman Craig, and their twin daughters, Mara and Cara, crash the vacation.
Ghost stories at the family BBQ include one of a man-eating grizzly bear that Chet met face-to-face when he was younger. Chet says that while he and Connie were honeymooning at the same lake, he was attacked by a giant grizzly bear. When he fired at it with a shotgun, the buckshot shaved the hair off the top of the bear's head and from that day on, it was known as the "Bald-Headed Bear" of Claire County.
After Roman pulls Chet around the lake on an impromptu water ski ride with his rented speedboat, tensions between the families erupt. Chet is ready to pack up and go home, even as his teenage son Buck tries to romance a local girl, Cammie. The budding romance goes well until Chet is challenged to eat the Old 96'er (a 96-ounce steak) at a family dinner which causes Buck to break their date. Buck tries to apologize to Cammie for being late, but Cammie refuses to speak to him.
Connie and Kate bond at a local bar when the conversation drifts to Kate's challenges of being wealthy. Later, just at the peak of tension between families, it emerges that Roman has made a bad investment and is broke. He has not told Kate and was planning to hit up Chet for the cash.
Later, during a thunderstorm, the twins wander off and fall into a mine shaft. Chet and Roman find them, but the claustrophobic Roman is reluctant to descend into the tiny mine shaft. After some encouragement from Chet, Roman summons up all his courage, while Chet goes in search of a rope to pull them out. Upon realizing that the mine is stocked with old dynamite, Roman takes his daughters and climbs out of the shaft on his own.

A:
What is the nickname of the person who encourages Roman to climb down the mine shaft?
