Passage: In 1933, a child orphaned during the Ukrainian Holodomor runs away from his orphanage and is taken in by a Red Army unit and adopted by its kindly commander, who gives him the name Leo Demidov. In 1945, now a sergeant with the unit, Leo  becomes an icon across the Soviet Union when he is photographed planting the Soviet flag atop the Reichstag during the Battle of Berlin. He becomes a Hero of the Soviet Union.
In 1953, Leo, now married to Raisa and living in Moscow, is a captain in the Ministry of State Security, commanding a unit tasked with tracking down and arresting dissidents. They arrest a veterinarian, Anatoly Brodsky, and during the arrest, one of Leo's subordinates, the cowardly but ambitious Vasili Nikitin, shoots a farmer, Semyon Okun, and his wife in whose barn Brodsky has been hiding, orphaning their two young daughters. Angry, Leo strikes Vasili, who harbours growing resentment against Leo and the other officer in the unit, Alexei Andreyev; all three were in Berlin together in 1945. Vasili is in charge of Brodsky's interrogation and execution, and one of the names he gives to their superior, Major Kuzmin, is that of Raisa, a primary school teacher, several of whose colleagues have recently been arrested for dissident views. Kuzmin orders Leo to investigate his own wife.
Meanwhile, Alexei's young son, Jora, is found dead near a railway yard. Although the initial pathology report shows injuries consistent with torture, the surgically precise removal of organs, and drowning, the authorities declare that he was hit by a train, as Stalin has decreed that murder is a capitalist disease; there is no murder in a communist paradise. Alexei is forced to accept the official conclusions to save himself and the rest of his family. 
Question: What is the profession of the man that the person in Leo's unit interrogates?
veterinarian.

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?
Richie.

Passage: In 1937 Mississippi during the Great Depression, three convicts, Ulysses Everett McGill, Pete Hogwallop, and Delmar O'Donnell, escape from a chain gang and set out to retrieve a supposed treasure Everett buried, before its locale is flooded to make a lake and provide electricity for the state. The three get a lift from a blind man driving a handcar on a railway. He tells them, among other prophecies, that they will find a fortune but not the one they seek. The trio make their way to the house of Wash, Pete's cousin. They sleep in the barn, but Wash reports them to Sheriff Cooley, who, along with his men, torches the barn. After Pete angrily blows up Cooley's police van, Wash's son helps them escape.
Pete and Delmar are baptized by a group of Christians at a river. The group then picks up Tommy Johnson, a young black man, who claims he has sold his soul to the devil in exchange for the ability to play the guitar. In need of money, the four stop at a radio broadcast tower where they record a song as The Soggy Bottom Boys. That night, the trio part ways with Tommy after their car is discovered by the police. Unbeknownst to them, the recording becomes a major hit.
The trio inadvertently fall in with bank robber George "Baby Face" Nelson, and help him with a heist, before he leaves them with his share of the loot. The next day, the group hears singing. They see three ladies washing clothes in a river and singing. The ladies drug them with corn liquor and they lose consciousness. Upon waking, Delmar finds Pete's clothes lying next to him, empty except for a toad. Delmar is convinced the ladies were Sirens and transformed Pete into the toad. Later, one-eyed Bible salesman Big Dan Teague invites them for a picnic lunch, then mugs them and kills the toad. 
Question: What are the full names of the people who see three ladies washing clothes in a river and singing?

Ulysses Everett McGill.
