You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

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?.
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.

New input: Passage: The documentary follows the travels of Armand Denis and his wife, Michaela Denis, as they travel around sub-Saharan Africa. Their safari begins in British East Africa, and continues on to Victoria Falls. From there they travel to South Africa, and trek up the coast of southwest Africa, before once more heading inland, where they meet with various African tribes. They fly to an animal farm run by Carr Hartley, where they learn how cheetahs are trained to hunt down other wild animals. The Denises next go to another animal farm, this one specializing in ostriches, where Michaela mounts and rides an ostrich. Their final stop is at a village where the local tribe is about to go on a gorilla hunt. The Denises go on the hunt with them, which results in the killing of two male gorillas who are taken back to the village to be eaten.
Other highlights of the safari include capturing a large sea lion in order to take a blood sample, and one of their carriers being attacked by a leopard they had been filming. The film offers wonderful vistas and some beautiful footage of wildlife including crocodiles, gazelles, elephants, gannets, antelopes, hippopotamus, water buffalos, penguins, and pelicans.
Solution:
Who do the Denises go on the hunt with?
