[EX Q]: Passage: Richie Donovan works as a professional thief for Groznyi, a wealthy businessman, to pay off his debt for being smuggled into the U.S. as a child. He pulls off an initially successful diamond heist, but it is botched when he is involved in two separate car accidents. He is given one last chance to pay off his debt by going to Russia to steal a priceless antique cross, locked in a safe in a Moscow penthouse apartment. Richie and his Russian accomplices, brothers Peter and Yuri, recover the cross; but their elevator becomes stuck on the uncompleted 13th floor. Believing the police have stopped the elevator, the thieves take their fellow passengers hostage to negotiate an escape. They agree to send one hostage down; but, when the elevator doors open on the ground floor, the hostage has mysteriously been beheaded.
The remaining hostages quickly divide into two groups: a Christian group consisting of Sonya, Helena and Katerina, who are later joined by Yuri, and another group consisting of nerdy Dmitry, beautiful Anna, and incompetent security guard Boris.
In the confusion, the Christian group seizes firearms and takes control, shooting Peter. Katerina is sent to stand guard over Richie and the remainder of the hostages, while Sonya takes Yuri to a chamber where he is to sacrificed by a wild man in armor named Alex. Yuri escapes, but he is impaled by one of Alex's traps, complete with disco music and lighting. In his rage, Alex kills Katerina, allowing Richie and the hostages to escape. They discover Alex's lair, where he has been watching everyone using security cameras. A photo reveals that Alex is the twin brother of Sonya, and they both believe themselves to be descendants of Ivan the Terrible. The group splits when Richie and Anna decide to chase after Alex, while Boris and Dmitry prefer to rig the room with various traps they have constructed and wait for Alex to come to them.
Question: Who are the people who think the authorities are responsible for the elevator stopping, leading them to take hostages?
[EX A]: Richie.

[EX Q]: Passage: Hilda Rix Nicholas (nee Rix, later Wright, 1 September 1884 3 August 1961) was an Australian artist. Hilda Rix was born in the Victorian city of Ballarat. Her father was an education administrator and poet, her mother was a musician and artist. She studied under a leading member of the Heidelberg School, Frederick McCubbin, at the National Gallery of Victoria Art School from 1902 to 1905 and was an early member of the Melbourne Society of Women Painters and Sculptors. Following the death of her father in 1907, Hilda Rix, her only sibling Elsie and her mother travelled to Europe where she undertook further study in London and then in Paris. Her teachers during the period included John Hassall, Richard Emil Miller and Theophile Steinlen.
After travelling to Tangiers in 1912, Rix held several successful exhibitions of her work, with one drawing, Grande marche, Tanger, purchased by the French government. She was one of the first Australians to paint post-impressionist landscapes, was made a member of the Societe des Peintres Orientalistes Francais, and had works hung in the Paris Salon first in 1911 and again in 1913. The family evacuated from France to England after the outbreak of World War I. A period of personal tragedy followed, as Rix's sister died in 1914, then her mother in 1915. In 1916 she met and married George Matson Nicholas, only to be widowed the next month when he was killed on the Western Front.
Returning to Australia in 1918, Rix Nicholas once more took up professional painting, and held an exhibition of over a hundred works at Melbourne's Guild Hall. Many sold, including In Picardy, purchased by the National Gallery of Victoria. Following a period painting in rural locations in the early 1920s, Rix Nicholas returned to Europe. A 1925 exhibition in Paris led to the sale of her work In Australia to the Musee du Luxembourg, followed by an extensive tour of her paintings around regional British art galleries. There followed representation in other exhibitions, including at the International Society of Sculptors, Painters and Gravers, and the Royal Academy of Arts, both in London. Following the inclusion of several works in the 1926 Societe Nationale des Beaux-Arts Spring exhibition in Paris she was made an Associate of that organisation.
Question: What is the full name of the person who studied at the National Gallery of Victoria Art School?
[EX A]: Hilda Rix Nicholas.

[EX Q]: Passage: Spoiled playboy Bob Merrick's (Rock Hudson) reckless behaviour causes him to lose control of his speedboat. Rescuers send for the nearest resuscitator, located in Dr. Phillips's house across the lake. While the resuscitator is being used to save Merrick, Dr. Phillips suffers a heart attack and dies. Merrick ends up a patient at Dr. Phillips's clinic, where most of the doctors and nurses resent the fact that Merrick inadvertently caused Dr. Phillips's death.
Helen Phillips, Dr. Phillips's widow, receives a flood of calls, letters, and visitors all offering to pay back loans that Dr. Phillips refused to accept repayment of during his life. Many claimed he refused by saying "it was already used up." Edward Randolph, a famous artist and Dr. Phillips's close friend, explains to Helen what that phrase means. This helps her to understand why her husband left little money, even though he had a very successful practice.
Merrick discovers why everyone dislikes him. He runs from the clinic but collapses in front of Helen's car and ends up back at the hospital, where she learns his true identity. After his discharge, Merrick leaves a party, drunk. Merrick runs off the road and ends up at the home of Edward Randolph, who recognizes him. Randolph explains the secret belief that powered his own art and Dr. Phillips's success. Merrick decides to try out this new philosophy. His first attempt causes Helen to step into the path of a car while trying to run away from Merrick's advances. She is left blind as a result of this accident.
Merrick soberly commits to becoming a doctor, trying to fulfill Dr. Phillips's legacy. He also has fallen in love with Helen and secretly helps her adjust to her blindness under the guise of being simply a poor medical student, Robby.
Question: What is the first name of the person who ends up a patient at Dr. Phillip's clinic?
[EX A]:
Bob.
