Instructions: 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.
Input: Passage: In the five years since the previous film, Fin has moved to a farm in Kansas named "April's Acres," where he lives with his mother Raye and young son Gil. April is believed dead after being crushed by the wreckage of the space shuttle. Tech mogul Aston Reynolds (based on Tesla, Inc. co-founder and SpaceX founder Elon Musk) has developed a new type of high-speed space travel with his company Astro-X (a play on SpaceX), which was used to save Fin's father, Colonel Gilbert Shepard, from the moon. Astro-X has also developed a technology that is capable of using radio waves to diffuse tornadoes, leading to the end of the sharknado phenomenon.
Fin travels to Molong with his cousin Gemini to meet up with his son Matt, who has returned from deployment in Iraq. Meanwhile, Reynolds has built and is opening a shark-themed hotel featuring a giant tank of sharks. While Matt and his fiancée, Gabrielle, marry and skydive from a plane, a sandstorm tornado develops that cannot be diffused by Astro-X. The tornado absorbs the water and sharks from Reynolds' hotel, creating the first sharknado in five years. The streets of Las Vegas flood, but Fin, Gemini, Gabrielle, and Matt work together to survive the storm until it heads back out into the desert.
Output:
Who's father did the tech mogul save?
