[Q]: Passage: Tchaikovsky was born in 1840 in Votkinsk, a small town in present-day Udmurtia, formerly the Imperial Russian province of Vyatka. A precocious pupil, he began piano lessons at the age of five, and could read music as adeptly as his teacher within three years. However, his parents' passion for his musical talent soon cooled. In 1850, the family decided to send Tchaikovsky to the Imperial School of Jurisprudence in Saint Petersburg. This establishment mainly served the lesser nobility or gentry, and would prepare him for a career as a civil servant. As the minimum age for acceptance was 12, Tchaikovsky was sent by his family to board at the Imperial School of Jurisprudence's preparatory school in Saint Petersburg, 800 miles (1,300 km) from his family home in Alapayevsk. Once Tchaikovsky came of age for acceptance, he was transferred to the Imperial School of Jurisprudence to begin a seven-year course of studies.Music was not a priority at the School, but Tchaikovsky regularly attended the theater and the opera with other students. He was fond of works by Rossini, Bellini, Verdi and Mozart. Piano manufacturer Franz Becker made occasional visits to the School as a token music teacher. This was the only formal music instruction Tchaikovsky received there. From 1855 the composer's father, Ilya Tchaikovsky, funded private lessons with Rudolph Kündinger, a well-known piano teacher from Nuremberg, and questioned Kündinger about a musical career for his son. Kündinger replied that nothing suggested a potential composer or even a fine performer. Tchaikovsky was told to finish his course and then try for a post in the Ministry of Justice.Tchaikovsky graduated on May 25, 1859 with the rank of titular counselor, a low rung on the civil service ladder. On June 15, he was appointed to the Ministry of Justice in Saint Petersburg. Six months later he became a junior assistant and two months after that, a senior assistant. Tchaikovsky remained there for the rest of his three-year civil service career.In 1861, Tchaikovsky attended classes in music theory organized by the Russian Musical Society and taught by Nikolai Zaremba. A year later he followed Zaremba to the Saint Petersburg Conservatory. Tchaikovsky would not give up his Ministry post "until I am quite certain that I am destined to be a musician rather than a civil servant." From 1862 to 1865 he studied harmony, counterpoint and fugue with Zaremba, while Rubinstein taught him instrumentation and composition. In 1863 he abandoned his civil service career and studied music full-time, graduating in December 1865. 
Question: What is the name of the full name of the man that the titular counselor studied under starting in 1861?
[A]: Nikolai Zaremba.


[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?
[A]: Richie.


[Q]: Passage: The cartoon begins with Mr. Meek carrying an axe in his hands. He turns to the audience and explains that his wife, Sweetypuss, told him that if he didn't bring home a roast duck for dinner, she would 'cook (his) goose'. (A parody of Wallace Wimple and his wife "Sweetie Face".)
The scene cuts to Daffy eating corn while singing "I Dream of Jeanie with the Light Brown Hair" minding his business. A shadow of Meek is show getting ready to chop off Daffy's head. Then he jumps and shouts "WATCH IT, BUB!!!" directly in his face.
After a brief talk to Meek, he flicks his beak at his face and marches to a hay stack. Meek chops the stack various times and on the last chop, he thinks he kills the duck. Daffy fakes his death by squirting ketchup and throwing his feathers around ("You crushed my little head!") This fools Meek by pretending he is beheaded and runs rapidly.
Meek feels sad and goes back to his house, where Daffy is seen putting lots of sugar cubes into a cup of coffee. Meek guiltily tells him that he has killed a duck. Daffy cheers up Meek into giving him a cup of coffee and asks how many lumps (of sugar) his wife usually gives him. Meek shows Daffy a 'lump' (a bump on his head), and Daffy hits him on the head (giving him another 'lump') and pours cream on it. Daffy dances on the cakes and pies, singing "Shortening Bread", and Meek immediately recognizes the duck he thought he killed ("Say. That's that Daffy Duck.") Daffy then utters 'YOU AIN'T JUST WHISTLING DIXIE!!!', then throws a pie at him, leading into a war between himself and Meek.
Daffy goes into army plane mode, by dropping an egg on Meek as a "Secret Bomb Site." Next, he goes into battle weaponry mode, by making various sounds and smashing household items. After all the fun and games are over, Meek gets mad, which causes the egg to fry on his head. 
Question: What is the full name of the person whose wife wants a roast duck for dinner?
[A]:
Mr. Meek.
