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.
Q: Passage: In 2045, people seek regular escape from life through the virtual reality entertainment universe OASIS, co-created by James Halliday and Ogden Morrow of Gregarious Games. After Halliday's death, a pre-recorded message left by his avatar Anorak announces a game, granting ownership of OASIS to the first to find the Golden Easter egg within it, which is locked behind a gate requiring three keys. The contest has lured a number of 'gunters', or egg hunters, and the interest of Nolan Sorrento, the CEO of Innovative Online Industries who seeks to control OASIS himself. IOI uses a number of indentured servants and employees called "Sixers" to find the egg.Wade Watts is an orphaned teenager living in the slums, or 'stacks', of Columbus, Ohio, with his Aunt Alice. In the OASIS, his avatar, Parzival, is best friends with Aech, a virtual mechanic. One day, Parzival befriends Art3mis, a well-known Gunter, sharing a common interest in Halliday's history. They review Halliday's life from the Archives, an online library of Halliday's life that came online upon the start of the games, with help from its Curator. They learn Halliday had several regrets in life, including his unrequited love for Morrow's wife Kira and losing Morrow as a friend after forcing him to sign away his part of Gregarious Games. Using this information, they solve the first two challenges of Anorak's game: a car race across an ever-shifting Manhattan cityscape and a search for Kira in the Overlook Hotel from The Shining. Aech and two other friends, Daito and Sho, soon follow suit, the group becoming known as the "High Five" on the OASIS scoreboards.
A:
