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: Agent Bart Langner finds Elsa Brinkmann, a would-be actress who looks and sounds just like  Lylah Clare, a flamboyant star who fell to her death in suspicious circumstances 20 years ago. He persuades arrogant director Lewis Zarkan, who had been married to Lylah, to see her. The two men then convince brash studio head Barney Sheean, who is equally struck, to back a picture with her as Lylah. 
Besides coping with the tyrannical Zarkan and easy access to alcohol and drugs, Elsa also has to contend with other hazards of Hollywood like malicious journalist Molly Luther and lesbian admirer Rossella. As filming continues, her identification with her rôle gets more intense. She also begins to fall in love with Zarkan, who is happy to sleep with her but his priority is to get his film finished. 
By the last day of shooting, her personality seems to have merged with that of the outrageous Lylah whose fatal fall, we learn, was prompted by the jealous Zarkan. To antagonise him, she first lets him find her in bed with the gardener. Then, as he directs her in a circus scene, she leaps to her death from the high-wire. The resulting publicity makes his film a huge success. Tragedy later comes when Zarkan himself is shot and killed by Rossella.
A final sequence (in this case, a TV commercial for dog food that interrupts the film itself) suggests that the world of Hollywood is literally one of dog eats dog.
Which person does Rossella admire?

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: After the release of Highway 61 Revisited in August 1965, Dylan set about hiring a touring band. Guitarist Mike Bloomfield and keyboard player Al Kooper had backed Dylan on his new album and at Dylan's controversial electric debut at the 1965 Newport Folk Festival. Bloomfield chose not to tour with Dylan, preferring to remain with the Paul Butterfield Blues Band. After backing him at concerts in late August and early September, Kooper informed Dylan he did not wish to continue touring with him. Dylan's manager, Albert Grossman, was in the process of setting up a grueling concert schedule that would keep Dylan on the road for the next nine months, touring the U.S., Australia, and Europe. Dylan contacted a group who were performing as Levon and the Hawks, consisting of Levon Helm from Arkansas and four Canadian musicians: Robbie Robertson, Rick Danko, Richard Manuel and Garth Hudson. They had come together as a band in Canada, backing American rocker Ronnie Hawkins. Two people had strongly recommended the Hawks to Dylan: Mary Martin, the executive secretary of Grossman, and blues singer John Hammond, Jr., son of record producer John Hammond, who had signed Dylan to Columbia Records in 1961; the Hawks had backed the younger Hammond on his 1965 album So Many Roads.Dylan rehearsed with the Hawks in Toronto on September 15, where they were playing a hometown residency at Friar's Club, and on September 24, they made their debut in Austin, Texas. Two weeks later, encouraged by the success of their Texas performance, Dylan took the Hawks into Studio A of Columbia Records in New York City. Their immediate task was to record a hit single as the follow-up to "Positively 4th Street", but Dylan was already shaping his next album, the third one that year backed by rock musicians.

What is the first name of the person who was in the Paul Butterfield Blues Band?
