Task: Question Generation
Input (English): Passage: In 1981 Afghanistan, a Soviet tank unit viciously attacks a Pashtun village harboring a group of mujahideen fighters. Following the assault, one of the tanks—commanded by ruthless commander Daskal (George Dzundza)—takes a wrong turn through a mountain pass and enters a blind valley. Taj returns to discover the village destroyed, his father killed, and his brother martyred by being crushed under Daskal's tank. As the new khan following his brother's death, Taj is spurred to seek revenge by his cousin Moustafa, an opportunistic scavenger. Together they lead a band of mujahideen fighters into the valley to pursue Daskal's tank (which they call "The Beast"), counting on their captured RPG-7 anti-tank weapon to destroy it.
Lost, isolated, and with their radio damaged in the attack, the tank crew set out to find Kandahar Road and return to Soviet lines. While camping for the night, Afghan communist crewman Samad educates the reluctant tank driver, Konstantin Koverchenko, about the Pashtun people's code of honour, Pashtunwali; particularly nanawatai, which requires that an enemy is to be given sanctuary if he asks.
Output (English): Who is responsible for killing the brother of the Khan?
