Task: Question Generation
Input (English): Passage: Hulk's allies, the Avengers, decide he is too dangerous to remain on Earth, so they put him in a shuttle and attempt to send him to a peaceful world. He awakens on board the shuttle before it arrives at its intended destination. When he goes into a fit of rage, breaking his restraints, he also causes enough damage to veer it off course, resulting in a crash on the planet Sakaar. Imperial guards appear and attach an obedience disk to Hulk, allowing them to communicate. Hulk is imprisoned with Hiroim, Korg, Miek, Elloe Kaifi, Lavin Skee, an Android, and a few hived natives.
The slaves are forced to fight for their freedom in three gladiator battles. Their first opponents are Korg's brothers. Lavin Skee and the natives die in the battle. Hulk attacks the Red King who presides over the arena, but is defeated by the emperor's lieutenant, Caiera. Red King allows the Hulk to live because the crowd is entertained, but secretly plots his death.
The other gladiators hold a service for Lavin Skee and form a Warbound pact, revealing their pasts to each other. Elloe also tells Hiroim that some civilians believe Hulk is the true "Sakaarson", a foretold savior. Hulk refuses the title. The other gladiators fight their second round against the Wildebots, and are victorious.
Later, Caiera comes to the Hulk and reveals her past. As a child, creatures known as "Spikes" attacked her home-town. The Red Prince (now the Red King) killed off the Spikes with his Death's Head guards (Hiroim called them Death's Hand) after which Caiera pledged allegiance to the prince. She worries Hulk's popularity will turn the people away from the Red King, and encourages him to escape. That night the resistance comes to rescue the gladiators but the Hulk refuses to go, warning there's a trap. Elloe leaves, and the rest of Warbound are forced to listen to the resistance fighters being attacked.
Output (English): What is the reason that the ally of the Avengers can speak?
