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: Married competitive gamer couple Max and Annie are trying to have a child, but their attempts are unsuccessful due to Max's stress surrounding his feelings of inadequacy when compared to his successful, attractive brother Brooks. During Max and Annie's routine weekend game night with their friends Ryan, and married couple Kevin and Michelle, Brooks shows up Max by arriving in a Corvette Stingray (Max's dream car) and sharing an embarrassing childhood story about Max. Brooks offers to host the next game night at a house he is renting while he is in town. Meanwhile, Max and Annie are trying to keep their game nights secret from their neighbor Gary, an awkward police officer left distraught after his divorce from their friend Debbie.
When the guests, including Ryan's new date, Sarah, arrive at Brooks' house the following week, Brooks says he has initiated an interactive role-playing mystery game, promising the winner his Stingray. A man dressed as an FBI agent bursts into the home and informs them of the narrative of the mystery, only for two masked men to break in and assault him and Brooks. The guests believe the assault is part of the game. After Brooks is dragged out of the house, the couples begin to solve the mystery using the clues left behind by the actor.
Using his GPS location, Max and Annie track Brooks down to a seedy bar and, using a pistol left behind by Brooks during the struggle (which they believe to be fake), manage to take the keys to the storage closet, where Brooks is being held. After Annie mistakenly fires the gun and shoots Max in the arm, confirming the weapon is real and that they are in actual danger, the three escape. Brooks admits that he actually makes his living buying and selling illegal items on the black market, in particular a Fabergé egg sought by a man known only as the Bulgarian and owned by a man using the alias Marlon Freeman. With his captors in pursuit, Brooks exits the moving car to guarantee Max and Annie's escape.
What are the first names of the people who are Debbie's friends?
