You will be given a definition of a task first, then some input 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: Jack Dempsey starts out fighting in bars for half the take. He wins his first professional fight.  After a later bout, he and his manager are held up at gunpoint and robbed of the purse. He sees the thieves later and beats them up to recover the cash. Jack meets Maxine Cates, but goes to New York to box. After a bout with John Lester Johnson is a draw, he breaks with his manager and goes back to Salt Lake City and marries Maxine. After money disputes with her Maxine leaves and Dempsey goes to San Francisco.  Kerns becomes his manager. He wins fights goes to New York and divorces Maxine. He beats Jess Willard by a TKO and becomes heavyweight champ. He goes to Hollywood to make films and gets sued for non-support by Maxine. He fights Luis Firpo and is knocked out of the ring, but still wins. He is sick (perhaps poisoned), but still fights Gene Tunney and loses a decision. On September 22, 1927 he fights Tunney again. Dempsey knocks Tunney down, but the count doesn't start until Dempsey goes to a neutral corner. This gives Tunney time to recover and get up when the count reaches 9. In this famous "long count" fight Tunney wins by decision.
Output:
Who does Gene Tunney win against in the famous "long count" fight?
