Task: Question Generation
Input (English): Passage: Gar Davis has to get out of Largo in a hurry because a man's been killed. He comes across a man in Comanche territory killed by an arrow. Gar takes the man's jacket, then shoves the corpse over a cliff, hoping the posse pursuing him will think he's the one who is dead.
Trying to steal a horse, Gar's face is grazed by a bullet shot by young Chad Grey, whose mother Celia tends to the stranger's wound. Indians attack the house. Gar helps fend them off, after which he and the Greys take off on horseback toward the safety of Fort Dobbs.
On the trail, an outlaw called Clett kills a Comanche who's about to bushwhack Gar, saving his life. Gar doesn't trust him, though, because Clett is carrying cases of rifles that he could be selling to the Indians rather than to soldiers at the fort.
Clett tries to take advantage of Celia, but even though Gar comes to her aid, Celia no longer trusts him because she's found the jacket Gar stole. It belonged to her husband, so Celia is now convinced that Gar murdered him, making her a widow.
Fort Dobbs' soldiers are all dead. A sheriff appreciates Gar's help fighting the Indians, but lets him know he must place Gar under arrest. Gar claims he killed the Largo man in self-defense after an argument. Permitted to ride to Santa Fe to get help, Gar ends up killing Clett for the rifles, bringing them back to save the fort and to win the widow's trust.
Output (English): What is the full name of the man who kills the outlaw who saved Gar's life?
