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: Going west where gold is being found, Jan Morell and wife Mary meet in the Napa, California, valley with his prospector brother Frank, but soon hired gunmen Jack Welch and Hank Purvis steal the gold they have panned and kill Mary.
In town, Frank is killed, as well, and Jan seriously wounded. He is cared for by Felipe de Ortega and sister Elena, who explain that Welch and Purvis work for dishonest Mayor Thomas Ainsworth, who also stole the Ortega family's land and property. An approval of statehood for California could restore law and order, as well as citizens' rights.
Elena fears for their safety, but Jan joins forces with Felipe's men to create havoc in Ainsworth's life, rustling horses and stealing money. A new U.S. marshal, Henderson, places a $5,000 reward on him, but Jan nevertheless captures Purvis and threatens to lynch him if he does not confess to Ainsworth's misdeeds. Elizabeth Ainsworth now begins to understand her father's corrupt ways.
As the gunfighting intensifies, both Welch and Felipe are killed. Jan is arrested and faces the hangman, but Henderson believes in his innocence and is able to release him when statehood wins approval and a general amnesty is granted. Jan and Elena plan a new life together.
What is the first name of the person who hired someone to kill Mary?

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.
Who comes under the tutelage of a math genius teacher?

Passage: It is Halloween in the small town of Pitchford Cove located somewhere in New England, and five high school friends, Phil, Mary, Mitch, Vinnie, and Melissa, plan on making it a night they will never forget. They steal outfits from the town's historic museum and come upon other old artifacts, including an old trunk encasing a paper scroll which contains an ancient curse. When Melissa, latent sorceress, recites the curse at the local cemetery, things take a turn for the worse.
The town's dead, led by Melissa's great-great-great-great-grandmother Lucinda Cavender, a witch who was put to death 300 years earlier, rise up from their graves and roam the town. As Melissa, Vinnie, Mitch, and Mary enjoy themselves at their annual Halloween costume party, Phil encounters a mysterious girl, named Sandra "Sandy" Matthews, dressed in a vintage 1950's cheerleader outfit, who warns him that the whole town is in danger.
Meanwhile, Lucinda and the various undead crash the costume party. At first, nobody pays much attention to them since everyone is in costume. However, Lucinda begins turning the party guests into vampires, starting with her great-great-great-great-granddaughter Melissa.
When Sandy discovers that Phil and his friends recited the ancient spell in the cemetery, they realize that the whole town is being overrun by the living dead and decide to team up to break the curse. The only way to do so is to find the Grenville Spirit Ring inside the grave of a witch-hunter Nathaniel Grenville - who, coincidentally, was Phil's great-great-great-great-grandfather and slave owner of Lucinda Cavender, her arch-nemesis - and use it to undo the curse.  Phil and "good ghost" Sandy must restore the town to normal by midnight before it is too late and the curse becomes permanent.
What is the last name of the person who crashes the party with other undead?
