[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: While Stafford was still working for Dorsey, Johnny Mercer told her, "Some day I'm going to have my own record company, and you're going to record for me." She subsequently became the first solo artist signed to Capitol after leaving the Pied Pipers in 1944. A key figure in helping Stafford to develop her solo career was Mike Nidorf, an agent who first heard her as a member of the Pied Pipers while he was serving as a Captain with the United States Army. Having previously discovered artists such as Glenn Miller, Artie Shaw, and Woody Herman, Nidorf was impressed by Stafford's voice, and contacted her when he was demobilized in 1944. After she agreed to let him represent her, he encouraged her to reduce her weight and arranged a string of engagements that raised her profile, and confidence.The success of Stafford's solo career led to a demand for personal appearances, and from February 1945 she embarked on a six-month residency at New York's La Martinique nightclub. Her performance was well-received—an article in the July 1945 edition of Band Leaders magazine described it as "sensational"—but Stafford did not enjoy singing before live audiences, and it was the only nightclub venue she ever played. Speaking about her discomfort with live performances, Stafford told a 1996 interview with The New Yorker's Nancy Franklin, "I'm basically a singer, period, and I think I'm really lousy up in front of an audience—it's just not me."Stafford's tenure with the United Service Organizations (USO) during World War II—which often saw her perform for soldiers stationed in the U.S.—led to her acquiring the nickname "G.I. Jo". On returning from the Pacific theater, a veteran told Stafford that the Japanese would play her records on loudspeakers in an attempt to make the U.S. troops homesick enough to surrender. She replied personally to all the letters she received from servicemen. Stafford was a favorite of many servicemen during both World War II and the Korean War; her recordings received extensive airplay on the American Forces radio and in some military hospitals at lights-out. Stafford's involvement with servicemen led to an interest in military history and a sound knowledge of it. Years after World War II, Stafford was a guest at a dinner party with a retired naval officer. When the discussion turned to a wartime action off Mindanao, the officer tried to correct Stafford, who held to her point. He countered her by saying, "Madame, I was there". A few days after the party, Stafford received a note of apology from him, saying he had re-read his logs and that she was correct. 
Question: What two wars was Stafford a favorite of many of the servicemen?
[A]: World War II.


[Q]: Passage: Middle-class Princeton student Tom Townsend, an admirer of Charles Fourier, attends a debutante dress ball one evening on a whim. After the ball, a mix-up leads to his meeting a small group of young Upper East Side socialites known as the Sally Fowler Rat Pack, after the girl whose apartment they use for after-hours parties. Believing that they accidentally stole a taxi from Tom, they decide to invite him to their after-hours party, to prevent ill feelings.
Tom decides to attend the party, and befriends several other attendees, including Nick Smith, a cynic who takes Tom under his wing; Audrey, a shy girl who enjoys Regency era literature and has a crush on Tom; and Charlie, an overly philosophical friend with an unrequited love for Audrey. Tom learns that he and the Rat Pack have some common friends, including his ex-girlfriend Serena Slocumb, with whom he remains infatuated.
Under Nick's tutelage, Tom ingratiates himself to the Rat Pack and soon becomes a full-fledged member. Much of the film is composed of dialogues in which Tom and the Rat Pack discuss the nebulous social scene they occupy, including how they are coming of age just as the culture in which they were raised is ending, leaving them with uncertain social futures. During these discussions, Tom reveals that he, too, was raised wealthy, but that his father abandoned the family to marry another woman, leaving Tom and his mother with limited financial resources. As a result, Tom harbors a love-hate relationship with wealth and the upper class. 
Question: What is the full name of the group that Tom becomes a member of?
[A]:
Sally Fowler Rat Pack.
