Given the task definition and input, reply with output. 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: In 1963, Ennis Del Mar and Jack Twist are hired by Joe Aguirre to herd his sheep through the summer in the Wyoming mountains. After a night of heavy drinking, Jack makes a pass at Ennis, who is initially hesitant but eventually responds to Jack's advances. Despite Ennis' telling Jack that it was a one-time incident, they develop a passionate sexual and emotional relationship. After Jack and Ennis eventually part ways, Ennis marries his longtime fiancée Alma Beers and has two daughters with her. Jack returns the next summer seeking work, but Aguirre, who had observed Jack and Ennis on the mountain, refuses to rehire him.
Jack moves to Texas, where he meets, marries, and has a son with rodeo rider Lureen Newsome. After four years, Jack visits Ennis. Upon meeting, the two kiss passionately, and Alma inadvertently observes this. Jack broaches the subject of creating a life with Ennis on a small ranch, but Ennis, haunted by a childhood memory of the torture and murder of two men suspected of homosexual behavior, refuses. He is also unwilling to abandon his family.
Ennis and Jack continue to meet for infrequent fishing trips as their respective marriages deteriorate. Lureen abandons the rodeo, going into business with her father and expecting Jack to work in sales. Alma and Ennis eventually divorce in 1975.  Upon hearing about Ennis' divorce, Jack drives to Wyoming. He suggests again that they live together, but Ennis refuses to move away from his children.
Jack finds solace with male prostitutes in Mexico. Ennis sees his family regularly until Alma finally confronts him about her knowing the true nature of his relationship with Jack. This results in a violent argument, causing Ennis to abandon his connections with Alma. Ennis meets and has a brief romantic relationship with Cassie Cartwright, a waitress.
Who does Joe Aguirre refuse to hire the next year?
