You will be given a summary of a story. You need to create a question that can be answered from the story. You can create a question about characters, events, facts and beliefs, etc. Your question should be specific, try not to use pronouns instead of full names. As the stories are sometimes movie plots, they will contain actor names in parentheses. You should not use those names. Only use character names. Try to ask a question about all parts of the plot, not just the beginning.

Let me give you an example: Mark Hunter (Slater), a high school student in a sleepy suburb of Phoenix, Arizona, starts an FM pirate radio station that broadcasts from the basement of his parents' house. Mark is a loner, an outsider, whose only outlet for his teenage angst and aggression is his unauthorized radio station. His pirate station's theme song is "Everybody Knows" by Leonard Cohen and there are glimpses of cassettes by such alternative musicians as The Jesus and Mary Chain, Camper Van Beethoven, Primal Scream, Soundgarden, Ice-T, Bad Brains, Concrete Blonde, Henry Rollins, and The Pixies. By day, Mark is seen as a loner, hardly talking to anyone around him; by night, he expresses his outsider views about what is wrong with American society. When he speaks his mind about what is going on at his school and in the community, more and more of his fellow students tune in to hear his show.
Nobody knows the true identity of "Hard Harry" or "Happy Harry Hard-on," as Mark refers to himself, until Nora Diniro (Mathis), a fellow student, tracks him down and confronts him the day after a student named Malcolm commits suicide after Harry attempts to reason with him. The radio show becomes increasingly popular and influential after Harry confronts the suicide head-on, exhorting his listeners to do something about their problems instead of surrendering to them through suicide at the crescendo of his yelled speech, an overachieving student named Paige Woodward (who has been a constant listener) jams her various medals and accolades into a microwave and turns it on. She then sits, watching the awards cook until the microwave explodes, injuring her. While this is happening, other students act out in cathartic release.
Eventually, the radio show causes so much trouble in the community that the FCC is called in to investigate. During the fracas, it is revealed that the school's principal (Annie Ross) has been expelling "problem students," namely, students with below-average standardized test scores, in an effort to boost the district's test scores while still keeping their names on the rolls (a criminal offense) in order to retain government funding.
Realizing he has started something huge, Mark decides it is up to him to end it. He dismantles his radio station and attaches it to his mother's old jeep, creating a mobile transmitter so his position can't be triangulated. Pursued by the police and the FCC, Nora drives the jeep around while Mark broadcasts. The harmonizer he uses to disguise his voice breaks, and with no time left to fix it, Mark decides to broadcast his final message as himself. They finally drive up to the crowd of protesting students, and Mark tells them that the world belongs to them and that they should make their own future. The police step in and arrest Mark and Nora. As they are taken away, Mark reminds the students to "talk hard." As the film ends, the voices of other students (and even one of the teachers) speak as intros for their own independent stations, which can be heard broadcasting across the country.
The answer to this example can be: What does Paige do with her medals?
Here is why: This is a good question and can be answered based on the story.

OK. solve this:
The Rangers (Rocky DeSantos, Adam Park, Billy Cranston, Aisha Campbell, Kimberly Hart, and Tommy Oliver) participate with Bulk and Skull in a charity skydive for the Angel Grove observatory, in anticipation of Ryan's Comet which will pass by in two days. Bulk and Skull miss the target landing zone and accidentally land on a construction site where a giant egg has been unearthed. Lord Zedd, Rita Repulsa, Goldar, and Mordant arrive at the construction site and crack open the egg, releasing Ivan Ooze, a morphological being who ruled Earth with an iron fist six thousand years earlier, before he was overthrown by Zordon and a group of young warriors under his charge. Ivan lays siege to the Rangers' Command Center and incapacitates Zordon, robbing the Rangers of their powers. As the Rangers return to the Command Center, they find it destroyed and Zordon dying.
Zordon's assistant Alpha 5 sends the Rangers to the distant planet Phaedos to obtain the Great Power and save Zordon. Ivan usurps Rita and Zedd, trapping them in a snow globe. Ivan sends his Tengu warriors to Phaedos and begins building an army. He uses his ooze to hypnotize the adults, forcing them to be his workforce to dig up his Ecto-Morphicon Titans, twin war machines built during his reign. When Fred Kelman, a friend of the Rangers', discovers his father missing, he finds him working at the construction site and discovers Ivan's plans.
On Phaedos, the Rangers and are almost killed by the Tengu, but are rescued by Dulcea, Phaedos' Master Warrior. After hearing of Zordon's plight, she agrees to help them and takes them to an ancient ruined temple, where the Rangers will have to overcome obstacles to acquire the power of the Ninjetti. Dulcea gives each Ranger an animal spirit: Aisha is the bear, Billy is the wolf, Rocky is the ape, Kimberly is the crane, Tommy is the falcon and Adam is the frog. The Rangers make their way to the Monolith housing the Great Power, defeat its four guardians, and retrieve the Great Power.
On Earth, Ivan's Ecto-Morphicons are completely unearthed, and he unleashes them on Angel Grove; he orders the parents to commit suicide at the construction site. Fred, Bulk, Skull and other students head to the construction site to save their parents. The Rangers return with their new animal-themed Ninja Zords and destroy one of Ivan's Ecto-Morphicons; Ivan takes control of the other and battles the Rangers himself. Coming up with a way to defeat him, the Rangers lead Ivan into space, right into the path of Ryan's Comet, which destroys him. His destruction breaks the hypnosis and the parents are reunited with their children. The Rangers then use the Great Power to restore the Command Center and resurrect Zordon.
In a mid-credits scene, Goldar briefly lounges in Zedd's throne being served by Mordant only to panic when Zedd and Rita appear having been released after Ivan was destroyed.
Answer:
What do the Rangers use to restore the Command Center?
