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:
In 2004, a satellite detects a mysterious heat bloom beneath Bouvet ya, an island about one thousand miles off the coast of Antarctica. Wealthy industrialist Charles Bishop Weyland (Lance Henriksen) discovers through thermal imaging that there is a pyramid buried 2000 feet beneath the ice. He attempts to claim it for his multinational communications company, Weyland Industries, a subsidiary of the Weyland Corporation, and assembles a team of experts to investigate. The team includes archaeologists, linguistic experts, drillers, mercenaries, and a guide named Alexa Woods (Sanaa Lathan).
As a Predator ship reaches Earth's orbit, it fires a beam that creates a passage through the ice towards the source of the heat bloom. When the team arrives at the abandoned whaling station above the heat source, they find the passage and descend beneath the ice. They locate the mysterious pyramid and begin to explore it, finding evidence of a prehistoric civilization and what appears to be a sacrificial chamber filled with human skeletons with ruptured rib cages.
Meanwhile, three Predators arrive and kill all the humans on the surface. They make their way down to the pyramid and arrive just as the team unwittingly activates the structure. The Alien Queen awakes from cryogenic stasis and begins to produce eggs. When the eggs hatch, several facehuggers attach themselves to humans trapped in the sacrificial chamber. Chestbursters emerge from the humans and quickly grow into adult Aliens. Conflict erupts between the Predators, Aliens, and humans, resulting in several deaths. Two Predators are killed by an Alien, and Weyland is killed by the remaining Predator, while allowing Alexa and archaeologist Sebastian De Rosa (Raoul Bova) enough time to escape. The two witness the Predator kill a facehugger and an Alien with a shuriken before unmasking and marking himself with the blood of the facehugger. After Alexa and Sebastian leave, another facehugger attaches itself to the unmasked Predator.
Through translation of the pyramid's hieroglyphs, Alexa and Sebastian learn that the Predators have been visiting Earth for thousands of years. It was they who taught early human civilizations how to build pyramids, and were worshiped as gods. Every 100 years they would visit Earth to take part in a rite of passage in which several humans would sacrifice themselves as hosts for the Aliens, creating the "ultimate prey" for the Predators to hunt. If overwhelmed, the Predators would activate a self-destruct device to eliminate the Aliens and themselves. The two deduce that this is why the current Predators are at the pyramid, and that the heat bloom was to attract humans for the sole purpose of making new Aliens to hunt.
Alexa and Sebastian decide that the Predators must be allowed to succeed in their hunt so that the Aliens "do not reach the surface". Unfortunately, Sebastian is captured by an Alien, leaving only Alexa and the Predator to fight against the Aliens. The two form an alliance and use a self-destruct device to destroy the pyramid and the remaining Aliens. Alexa and Scar reach the surface, where they battle the Alien Queen. They defeat the Queen by attaching its chain to a water tower and pushing her over a cliff, dragging the Queen to the ocean floor. Scar, however, is impaled through the torso by the Alien Queen's tail and succumbs to his wounds and dies.
A Predator ship uncloaks and several Predators appear. They retrieve their fallen comrade and an elite Predator presents Alexa with one of their spear weapons in recognition of her skill as a warrior. As the Predators retreat into space, a chestburster with a hybrid form of an Alien and a Predator erupts from Scar's chest, beginning the events of Aliens vs. Predator: Requiem.
Answer:
Why do the Predators visit Earth?
