Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Reason: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

Now, solve this instance: Passage: Serving four years of his ten-year sentence for armed robbery, Carter "Doc" McCoy is denied parole from a Texas prison. When his wife Carol visits him, he tells her to do whatever is necessary to make a deal with Jack Beynon, a corrupt businessman in San Antonio, to free him. Beynon uses his influence and obtains Doc's parole on the condition that he take part in a bank robbery with two of his henchmen, Rudy and Frank. Frank kills a guard, then Rudy attempts a double-cross, killing Frank and drawing on Doc, who quickly reacts and shoots Rudy several times. Doc takes the $500,000 ($3.0 million today) and leaves. Rudy, having secretly worn a bulletproof vest, is only wounded.
Doc meets with Beynon, who attempts a double-cross before Carol shoots and kills him. Doc realizes that Carol had sex with Beynon to secure his parole. Doc angrily gathers up the money and, after a bitter quarrel, the couple flees for the border at El Paso.
A bloodied Rudy forces rural veterinarian Harold and his wife Fran to treat his injuries, then kidnaps them to pursue Doc and Carol. Beynon's brother Cully and his thugs also pursue the McCoys. At a train station, a con man swaps locker keys with Carol and steals their bag of money. Doc follows him onto a train and forcefully takes it back. The injured con man and a train passenger a boy whom Doc had rebuked for squirting him with a water gun are taken to the police station, where they identify Doc's mug shot.
Student:
Who is the henchman pursuing the bank robber and his wife?
