Given the task definition, example input & output, solve the new input case.
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.
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.
Output: Who believes Fagin's gang make wallets and handkerchiefs?.
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 case for you: Passage: Set in the Stone Age, Ishbo is the younger son of Mookoo, the leader of a tribe of cavemen. Ishbo is smarter than most of his tribesmen, but awkward and nerdy, living in the shadow of his much more physically impressive brother Thudnik. He hopes to use his superior intellect to become an inventor and raise his tribe above simple sticks and stones, but due to a combination of the flimsy materials available to him and the lack of support from his tribe they always fail. Ishbo also has had a lifelong crush on his childhood friend, Fardart. Much to his dismay, immediately after he finally expresses his love to her she is "clubbed" by Thudnik (and all that follows in the tradition of caveman stereotypes), and eventually married to him. Ishbo himself has never clubbed a woman, having his heart set on Fardart his whole life.
After Fardart is betrothed to Thudnik, Ishbo begins to believe that he will never club a woman. He at first is too attached to her to consider clubbing another woman, and is further discouraged after a particularly ill-fated attempt at clubbing. Ishbo becomes quite depressed, a feeling which is escalated by his failure to prove useful on a mammoth hunt. He falls into a large pile of mammoth dung, then is eaten by the mammoth, and eventually excreted (or extracted – the scene itself appears as a series of animated cave drawings) from the mammoth when it is finally killed by the rest of the tribesmen.
Output:
What is the name of the person who hopes to become an inventor?
