[EX Q]: Passage: On a train trip, lawyer Richard Grant tells fellow passengers that, based on his long experience both prosecuting and defending murder cases, murder is sometimes justified and a clever man should be able to commit it undetected. He is traveling to the isolated estate of his wealthy client and friend, Gordon Rich; his young adult daughter Barbara surprises him at the train station, where she informs him that she has already been there a week.
Grant's view is soon put to the test. Rich asks him to rewrite his will, including bequests to all his former mistresses (except one who is dead already; she was just 16, and Grant believes it was suicide). When Rich explains that he wants a new will because he intends to marry Barbara, Grant is appalled. He repeats what he said on the train. Rich deserves to be murdered, and if that is what it takes to stop the marriage, Grant will do it and get away with it. Rich retorts that if necessary he will retaliate from beyond the grave.
Grant pleads with his daughter, pointing out the great age difference and Rich's indecent character. But she loves Rich and is adamant. Nor has Tommy Osgood, a young man Barbara had been seeing, been able to change her mind.
At a dinner party that night, Rich announces the wedding and says it will take place in the morning. His longtime girlfriend, Marjorie West, is dismayed, but after the party he assures her that, as usual, he will return to her once he exhausts his obsession with Barbara. He is only marrying Barbara because she would not go to bed with him otherwise.
Rich orders two servants to watch Grant's bungalow on the estate, but Grant uses a cutout mounted on a record player to cast a moving shadow on the curtain to make it appear that he is pacing restlessly, and slips back to the main house. Meanwhile, Rich goes to Barbara's room. He loses control and grabs her roughly; she recoils in disgust and he leaves. 
Question: What is the full name of the person who is surprised by someone at the train station?
[EX A]: Richard Grant.

[EX Q]: Passage: Will Rodman, a scientist at the San Francisco biotech company Gen-Sys, is testing the viral-based drug ALZ-112 on chimpanzees to find a cure for Alzheimer's disease. ALZ-112 is given to a chimp named Bright Eyes, greatly increasing her intelligence. But then, during Will's presentation for the drug, Bright Eyes is forced from her cage, goes on a rampage and is shot to death. Will's boss Steven Jacobs terminates the project and has the chimps slaughtered. However, Will's assistant Robert Franklin discovers that the reason for Bright Eyes' rampage was that she had recently given birth to an infant chimp. Will reluctantly agrees to take in the chimp, who is named Caesar. Will learns that Caesar has his mother's intelligence, through being exposed to ALZ-112 in her womb, and decides to raise him. Three years later, Will introduces Caesar to the redwood forest at Muir Woods National Monument. Meanwhile, Will treats his dementia-suffering father Charles with ALZ-112, which seems to restore his cognitive ability. 
Question: What is the name of the infant chimp's mother?
[EX A]: Bright Eyes.

[EX Q]: Passage: Massenet returned to Paris in 1866. He made a living by teaching the piano and publishing songs, piano pieces and orchestral suites, all in the popular style of the day. Prix de Rome winners were sometimes invited by the Opéra-Comique in Paris to compose a work for performance there. At Thomas's instigation, Massenet was commissioned to write a one-act opéra comique, La grand'tante,  presented in April 1867. At around the same time he composed a Requiem, which has not survived. In 1868 he met Georges Hartmann, who became his publisher and was his mentor for twenty-five years; Hartmann's journalistic contacts did much to promote his protégé's reputation.In October 1866 Massenet and Ninon were married; their only child, Juliette, was born in 1868. Massenet's musical career was briefly interrupted by the Franco-Prussian War of 1870–71, during which he served as a volunteer in the National Guard alongside his friend Bizet. He found the war so "utterly terrible" that he refused to write about it in his memoirs. He and his family were trapped in the Siege of Paris but managed to get out before the horrors of the Paris Commune began; the family stayed for some months in Bayonne, in southwestern France.After order was restored, Massenet returned to Paris where he completed his first large-scale stage work, an opéra comique in four acts, Don César de Bazan (Paris, 1872). It was a failure, but in 1873 he succeeded with his incidental music to Leconte de Lisle's tragedy  Les Érinnyes and with the dramatic oratorio, Marie-Magdeleine, both of which were performed at the Théâtre de l'Odéon. His reputation as a composer was growing, but at this stage he earned most of his income from teaching, giving lessons for six hours a day. 
Question: What is the name of the 1872 large-scale stage work that was a failure?
[EX A]:
Don César de Bazan.
