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.

Let me give you an 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.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is why: 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.

OK. solve this:
Passage: In 1878 a hardened American gunfighter arrives in a small town in the foothills of the Canadian Rockies, a place that doesn't understand or appreciate the brutal code of the American Wild West.
Gunslinger Sean Lafferty, known as the Montana Kid, has a bounty on his head for killing eleven people across the western United States.  He arrives in town on his horse, riding backwards, bound, with a noose around his neck, and dragging the broken tree branch over which a group had tried to hang him on the American side of the border. After being helped off his horse by a young Chinese girl named Adell, he begins to explore the town, starting with the town general store. After leaving the store, he finds his horse gone and accuses Jack, the blacksmith, of stealing it, even though Jack was simply replacing the horse's damaged shoes. After unsuccessfully trying to intimidate the blacksmith, the Montana Kid decides to call him out. Since the blacksmith has no gun, though, Sean can't shoot him because the Kid lives by a code of ethics that prevents him from killing unarmed men.
When she witnesses this, Jane Taylor, one of the townsfolk, says the Kid can have her broken gun (to fix and give to Jack) if he builds her a windmill. Sean proceeds to go with her and stays in a sod house at her farm, alternately working on the windmill and repairing the gun. After a few days, however, the Kid begins to develop feelings toward Jane while also becoming friends with the townsfolk.
In the meantime, a roaming band of American bounty hunters crosses into Canada and heads for the town to claim the price on Sean's head. They terrorize a camp of Chinese railroad workers to find out his whereabouts.
Answer:
What is the alias of the person who rides his horse backwards with a noose on his neck?
