Given the task definition and input, reply with output. In this task, you will be shown an extract from a movie plot. You need to read the extract and create questions that can be answered from the extract. The questions should be well-formed and grammatically correct. The questions should be completely answerable from the given passage and should not require any external knowledge. Subjective questions are not allowed. Create questions that result in factoid answers. A simple rule of thumb to decide whether a question is factoid or not is to see if two different people with average reading/comprehension skills would come up with the same answer after reading the passage.

Genius, billionaire, and playboy Tony Stark, who has inherited the defense contractor Stark Industries from his father, is in war-torn Afghanistan with his friend and military liaison, Lieutenant Colonel James Rhodes to demonstrate the new "Jericho" missile. After the demonstration, the convoy is ambushed and Stark is critically wounded by one of his own rocket-propelled grenades. He is captured and imprisoned in a cave by a terrorist group, the Ten Rings, and an electromagnet is grafted into his chest by fellow captive Yinsen to keep the shrapnel shards that wounded him from reaching his heart and killing him. Ten Rings leader Raza offers Stark freedom in exchange for building a Jericho missile for the group, but Tony and Yinsen agree Raza will not keep his word.Stark and Yinsen quietly build a powerful electric generator called an arc reactor to power Stark's electromagnet and a suit of powered armor to aid in their escape. Although they keep the suit hidden almost to completion, the Ten Rings attack the workshop when they discover their hostages' intentions. Yinsen sacrifices himself to divert them while the suit powers up. The armored Stark battles his way out of the cave to find the dying Yinsen, then in anger burns the Ten Rings weapons and flies away, crashing in the desert and destroying the suit. After being rescued by Rhodes, Stark returns home and announces that his company will no longer manufacture weapons. Obadiah Stane, his father's old partner and the company's manager, advises Stark that this may ruin Stark Industries and his father's legacy. In his home workshop, Stark builds a sleeker, more powerful version of his improvised armor suit, as well as a more powerful arc reactor for his chest. Personal assistant Pepper Potts places the original reactor inside a small glass showcase. Though Stane requests details, Stark keeps his work to himself.At a charity event held by Stark Industries, reporter Christine Everhart informs Stark that his company's weapons, including the Jericho, were recently delivered to the Ten Rings and are being used to attack Yinsen's home village, Gulmira. Stark also learns Stane is trying to replace him as head of the company. Enraged by these revelations, Stark dons his new armor and flies to Afghanistan, where he saves Yinsen's village. While flying home, Stark is shot at by two F-22 Raptor fighter jets. He reveals his secret identity to Rhodes over the phone in an attempt to end the attack. Meanwhile, the Ten Rings gather the pieces of Stark's prototype suit and meet with Stane, who subdues Raza and has the rest of the group killed. Stane has a massive new suit reverse engineered from the wreckage. Seeking to find any other weapons delivered to the Ten Rings, Stark sends Pepper to hack into the company computer system from Stane's office. She discovers Stane has been supplying the terrorists and hired the Ten Rings to kill Stark, but the group reneged. Potts meets with Agent Phil Coulson of S.H.I.E.L.D., a counter-terrorism agency, to inform him of Stane's activities.Stane's scientists cannot duplicate Stark's arc reactor, so Stane ambushes Stark at his home and takes the one from his chest. Stark manages to get to his original reactor to replace the taken one. Potts and several S.H.I.E.L.D. agents attempt to arrest Stane, but he dons his suit and attacks them. Stark fights Stane, but is outmatched without his new reactor to run his suit at full capacity. The fight carries Stark and Stane to the top of the Stark Industries building, and Stark instructs Potts to overload the large arc reactor powering the building. This unleashes a massive electrical surge that causes Stane and his armor to fall into the exploding reactor, killing him. The next day, at a press conference, Stark defies suggestions from S.H.I.E.L.D. and publicly admits to being the superhero the press has dubbed "Iron Man".In a post-credits scene, S.H.I.E.L.D. Director Nick Fury visits Stark at home, telling him that Iron Man is not "the only superhero in the world", and explaining that he wants to discuss the "Avenger Initiative".
What is the name of the terrorist group that captures Tony Stark?
