In this task, you will be shown an extract from a movie plot and a question. You need to provide the correct answer for it. Short answers containing words that are present in the passage are preferred.

Example Input: Dr. Carter Nix (John Lithgow) is a respected child psychologist. His wife, Jenny (Lolita Davidovich), becomes concerned that Carter is obsessively studying their daughter, Amy; he regards her like a scientist tracking the development of his creation. But Carter himself suffers from multiple personality disorder consisting of Cain, a street hustler, Josh, a shy 10-year-old boy, and Margo, a middle-aged nanny. Carter and Cain are killing young mothers to procure their children for his experiments.Jenny is having an affair with Jack Dante (Steven Bauer), the widower of a former patient. She had a relationship with him years ago, but he left her. Now she plans to leave Carter and elope with him. When Carter accidentally discovers their tryst, he descends completely into his madness and begins leaving subtle clues for the police that Jack is the real killer. Next, he attempts to kill Jenny by submerging her car in a lake. She escapes and confronts Carter at home. Unable to find Amy, Jenny demands Carter tell her where she is. Carter replies that she is with his father, whom Jenny knows has been dead for years.Carter is apprehended for attempted murder. The police bring Dr. Lynn Waldheim (Frances Sternhagen) to interrogate him. Waldheim interviews Carter and informs the police that she co-wrote a book with Nix Sr. called Raising Cain, about a boy with multiple personality disorder. Nix Sr. had extensive detailed knowledge of Cain's tortured childhood, including taped recordings of their sessions. However, Waldheim was never allowed to meet Cain. She pieced the situation together: Nix Sr. dispassionately put his own son through years of severe child abuse to gain firsthand accounts of his traumatic psychological development and study the emerging personalities. Horrified, Waldheim quit the project.During interrogation, Margo and Josh act and speak for Carter. Josh recites a rhyme and vanishes, and Margo assumes control. She stonewalls Waldheim from any further questioning. Eventually, Carter and Cain break from their confines. They pounce upon Dr. Waldheim, knocking her unconscious and leaving the building disguised as her. The police soon find Waldheim begging them to arrest Carter before any children are harmed.Nix Sr. (Lithgow) is in fact alive, having faked his own death to elude prosecution for attempting to buy babies. He has established a new identity and a clandestine research facility in Norway. He has been using Carter and his multiples to procure the children so he will have an adequate control group to study the development of MPD. Jenny follows who she thinks is Waldheim to a motel, but it is actually Carter/Cain. She follows Carter/Cain, who is now Margo, into an elevator. When it opens, she sees Nix Sr. with her daughter Amy. While Jenny begs for Nix Sr. to give back her daughter, Carter, Cain and Margo stabs "their" father from behind. Jack arrives with the police, and Carter and his personalities disappear.The movie ends with Jenny and Amy in a park. Amy runs off into the woods calling "Daddy, Daddy". Jenny follows her and finds Amy, who says her father has gone away. When Jenny bends down to pick Amy up, Carter appears behind her in a wig and a dress; Margo is now in control. Jenny holds Amy in her arms, oblivious to who is behind her., Question: What does he need the children for?
Example Output: Answer: Study the development of MPD.

Example Input: This article's plot summary may be too long or excessively detailed. Please help improve it by removing unnecessary details and making it more concise. (October 2011) (Learn how and when to remove this template message)In a two-dimensional world called Flatland populated by living squares, triangles, circles and other two-dimensional shapes, it is three days until the celebration of the year 3000. A Square, attorney at law, struggles to instruct his grandson, A Hexagon, in the art of sight recognition. The lesson is interrupted by A Square's brother B, a clerk to President Circle, warning A to stay home during a meeting at the Senate of the Great Southern Republic of Flatland.The Senate session has been called to discuss the increasing hostilities between the government and the Chromatist movement, led by Senator Chromatistes, an irregular dodecagon. The movement seeks legalization of the right of Flatlanders to color their sides as they see fit. Traditionally taboo, laws against it had been relaxed; this emboldened the Chromatists to demand legalization. The Great Southern Republic distinguishes itself from its enemy, the Northern Kingdom, by its stances on Chromatism and Irregulars along with a democratic government. Relaxing the laws has already been perceived as weakness by the Northern Kingdom who are massing on the borders.Against his brother's warning, A Square meets his new client, the first female charged as a Chromatist; on his way home he is caught in the melee leaving the Senate. President Circle's soldiers killed Senator Chromatistes and his supporters, sparking a riot across the city. A Square just gets home safely, then barricades his family against the chaos for the night.Once asleep, A Square dreams of visiting a one-dimensional world, Lineland, and attempts to convince the realm's ignorant king of a second dimension, but fails to make him see outside of his eternally straight line. A Square awakens to learn that the deadly riots originated in the Senate meeting that B Square was attending. A visit to B Square's home confirms that he is missing. A Square scours the city, now under martial law, seeking B Square. At the marketplace, he meets a merchant selling a fascinating "glow point", and buys one for A Hexagon, who has been sulking since being disciplined for coloring one of his sides purple.The family prepares for another anxious night, only to be terrified by the sudden appearance of A Sphere, CEO of Messiah, Inc. A Sphere declares that A Square is his apostle of the Three Dimensions and privately begins to explain things to him. A Square refuses to entertain the notion of three dimensions, resorting to violence with A Sphere. A Sphere decides the only way to convince A Square of the three dimensions is to show him.Suddenly and painfully, A Square is plucked out of his dimension and into Spaceland. After the initial shock, the reality of 3 dimensions becomes clear to A Square, along with the possibility of locating his brother from his newfound vantage point. Having business himself at the Great Hall, A Sphere brings A Square to look for his brother there. On their arrival, A Sphere expounds upon three dimensions to President Circle and the Priests who anticipated this event. After rejecting A Sphere's message and attempting to kill him, the Flatland leaders execute all who have witnessed the event, except B Square, who is imprisoned for life on pain of death in exchange for his silence while his brother watches from high above Flatland.Realizing that time in Spaceland is short, at least for A Square, A Sphere brings him to Messiah, Inc. to finish his education on the gospel of Three Dimensions. Enthralled by the complex world of Spaceland, A Square posits further about 4 dimensions and so forth to A Sphere who dismisses it as nonsense. Meanwhile, A Square's intrusion into Spaceland has become a national emergency, which prompts the Spaceland Senate to call to him to appear for a hearing, to explain this breach of protocol of bringing a Flatlander into their midst. They claim it will be viewed as an act of, and provocation for, war by their enemies, the X-Axis.During the hearing, A Square also learns that the X-Axis considers the Great Senate as weak because they have allowed the continued existence of his own world, Flatland, which they view as an abomination. As the debate rages, an ailing A Square tries to explain his theory of multiple dimensions to an unsympathetic crowd. Air-raid sirens wail as A Square collapses from the overwhelming effects of gravity on his two-dimensional body and chaos ensues.A Sphere manages to send his dying apostle back on his way to Flatland via a mailing tube before bombs destroy both Messiah, Inc. and A Sphere himself, but A Square's journey back is halted by A Sphere's hovercraft, who attempts to crush A Square to avenge A Sphere's death. But, an X-Axis ship crashes into and destroys the hovercraft, and A Square ends up plunging in freefall toward Flatland and through its surface into unknown regions below, where he experiences a revelation on dimensionality and infinity.A Square finds himself in his own bed on the eve of the year 3000 and his family informs him that the government has issued orders for the arrest of anyone proclaiming the gospel of three dimensions. Undeterred, A Square hurries to see his brother in Flatland jail to discuss their new shared knowledge of the third dimension. B Square, afraid of execution, denies the experience and in a panic assaults his brother who falls temporarily into an unconscious state where he encounters A HyperSphere along with the Monarch of Pointland who curiously resembles a "glow point." As the Monarch drones on in his monologue of "being the all in all, the one in the one," A HyperSphere informs his former apostle that time is short and A Square must proclaim the gospel of the three dimensions to his fellow Flatlanders although they, like the Monarch, will probably remain trapped within their own perspectives.Returning to himself, A Square escapes Flatland prison and outruns the guards. Arriving home, A Square informs his wife that they are going to defect to the Northern Kingdom where he might be able to spread the gospel of three dimensions to a more open minded populace. The soldiers arrive and A Square escapes with the help of Frau A Square's "war cry" that temporarily stuns them. Before he can reach the border, A Square is cornered by the soldiers whose attempt to dismantle and segment him is thwarted by the Northern Kingdom army's attack. In the fracas, things suddenly begin to disappear as though sucked down through the fabric of Flatland until only A Square remains. He too begins to disappear until there is only his eye, then a point of light, a glowing point of light, which welcomes him into another dimension., Question: How is time in Spaceland described?
Example Output: Answer: As short

One day, he is ambushed in his home by Roland Cox (Samuel L. Jackson), a member of the Paladins, a group of religious extremists who have been tracking down and killing "Jumpers".

He returns to Ann Arbor, seeking his old crush Millie (Rachel Bilson). When Mark (Teddy Dunn) attacks him, David teleports him into a bank vault and leaves him there. David then returns to Millie and invites her on a trip to Rome. Roland later discovers Mark in police custody and learns David's identity.In Rome, David and Millie grow closer, though he keeps his ability a secret.

David breaks into Millie's apartment, angering her. Seeing Roland arriving, David decides to reveal the truth to her. He teleports her to Griffin's hideout. Using a machine that keeps David's "jump scar" open, the Paladins, including Roland, invade the hideout. David and Griffin subdue most of them. Roland is chased back through the jump scar, but he manages to snatch Millie with him. He sets up a trap in Millie's apartment, expecting David to come back for her.Obsessed with killing Roland, Griffin plans to bomb the apartment; but David objects, wanting to save Millie. They fight and David traps Griffin with power lines in Chechnya. Ignoring Griffin's warning, David jumps to Millie's apartment and is quickly trapped by Roland's cables. The cables "link" him to the apartment, making him unable to jump away alone. Mustering his strength, David teleports the apartment and everyone inside to a river. Once free of the cables, David teleports Millie to safety and dumps Roland in a cave in the Grand Canyon. He leaves Roland there, explaining that not all Jumpers are a threat to be destroyed.David visits his mother and discovers his half-sister, Sophie (Kristen Stewart).
