TASK DEFINITION: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
PROBLEM: Passage: En route to California to prospect for gold, ex-sheriff Hooker, professional gambler Fiske, and bounty hunter Luke Daly are forced to stop over in a tiny Mexican village by engine trouble on the ship they are taking. A desperate Leah Fuller hires the three men and local Vicente Madariaga, to rescue her husband, John, who is pinned under debris from a gold mine cave-in in hostile Apache territory.
During the harrowing journey, Luke tries to force himself on Leah late one night, forcing Hooker to intervene. Leah tells Hooker that where her husband is trapped, once was a boom town, but a volcano eruption wiped it out, leaving only a church steeple and the mine uncovered by lava. The resident priest called it the "garden of evil". The Indians now consider the volcano sacred. The group then arrives at the mine. They find John unconscious, and they free him.
Before John wakes up, Hooker sets the man's broken leg.  When John regains consciousness, he accuses Leah of using him to get gold. Hooker talks to Leah later, about what her husband said; after he tells her that he has spotted signs of Apaches nearby, she offers him and the others all the gold they have dug up to take her husband away that night, while she remains behind to make it look like they are all still there. The cynical Fiske unexpectedly offers to stay with her, but when he asks her what he is to her, she tells him, "you're nothing at all, just nothing.".

SOLUTION: What are the full names of the two people that travel with the ex-sheriff?

PROBLEM: Passage: Following the end of the Second World War, the East German side of the border was guarded initially by the Border Troops (Pogranichnyie Voiska) of the Soviet NKVD (later the KGB). They were supplemented from 1946 by a locally recruited paramilitary force, the German Border Police (Deutsche Grenzpolizei or DGP), before the Soviets handed over full control of the border to the East Germans in 1955/56. In 1961, the DGP was converted into a military force within the National People's Army (Nationale Volksarmee, NVA). The newly renamed Border Troops of the GDR (Grenztruppen der DDR, commonly nicknamed the Grenzer) came under the NVA's Border Command or Grenzkommando. They were responsible for securing and defending the borders with West Germany, Czechoslovakia, Poland, the Baltic Sea and West Berlin. At their peak, the Grenztruppen had up to 50,000 personnel.Around half of the Grenztruppen were conscripts, a lower proportion than in other branches of the East German armed forces. Many potential recruits were screened out as potentially unreliable; for instance, actively religious individuals or those with close relatives in West Germany. They were all subjected to close scrutiny to assure their political reliability and were given intensive ideological indoctrination.A special unit of the Stasi secret police worked covertly within the Grenztruppen, posing as regular border guards, between 1968 and 1985, to weed out potential defectors. One in ten officers and one in thirty enlisted men were said to have been recruited by the Stasi as informers. The Stasi regularly interviewed and maintained files on every guard. Stasi operatives were directly responsible for some aspects of security; passport control stations at crossings were manned by Stasi officers wearing Grenztruppen uniforms.The Grenztruppen were closely watched to ensure that they could not take advantage of their inside knowledge to escape across the border. Patrols, watchtowers and observation posts were always manned by two or three guards at a time. They were not allowed to go out of each other's sight in any circumstances. If a guard attempted to escape, his colleagues were under instructions to shoot him without hesitation or prior warning; 2,500 did escape to the West, 5,500 more were caught and imprisoned for up to five years, and a number were shot and killed or injured in the attempt.
The work of the guards involved carrying out repair work on the defences, monitoring the zone from watchtowers and bunkers and patrolling the line several times a day. Border Reconnaissance (Grenzaufklärungszug or GAK) soldiers, an elite reconnaissance force, carried out patrols and intelligence-gathering on the western side of the fence. Western visitors to the border were routinely photographed by the GAKs, who also oversaw work detachments maintaining the fence. The workers would be covered by machine guns to discourage them from attempting to escape.

SOLUTION: What is the nickname of the group that screened out many potential recruits?

PROBLEM: Passage: The film opens with Tammy at cheerleader practice, while her boyfriend Michael walks in from football practice to observe. The two of them meet Byron, Tammy's gay friend, who approves of Michael as her new boyfriend. Shortly thereafter, Tammy's violent and jealous ex-boyfriend Billy arrives with his gang and harasses Michael. A fight erupts between the two. However, the police arrive to break up the fight and take Billy into custody, but Tammy, unable to deal with the events, breaks down and runs away in tears.
The scene then cuts to a figure of a T-Rex in a dark warehouse as two people, Dr. Wachenstein and his assistant Helga, walk through the doors. The lights come on and the T-Rex figure begins to move, being controlled by someone in a room. The Dr. is impressed by the robotic dinosaur's strength, and reveals his plan to implant a living human brain into the robot to give it consciousness, mobility and, "immortality".
Later that night, Michael sneaks out to see Tammy. They are soon interrupted by Billy and his thugs, who chase and catch Michael. They throw him into the wild Animal Park where lions and jaguars run loose. A lion mauls Michael and he is left in a comatose state. He is brought to a hospital where his intoxicated uncle watches over him.

SOLUTION:
Whose ex-boyfriend shows up to harass Michael?
