Task: Question Generation
Input (English): Passage: On January 5, 1900, four friends arrive for a dinner at the London home of their inventor friend George, but he is not there. He arrives suddenly, bedraggled and exhausted, and begins describing the strange experiences he has had since they last met.
At their earlier dinner on New Year's Eve, George said that time was "the fourth dimension". He shows David Filby, Dr. Philip Hillyer, Anthony Bridewell, and Walter Kemp a small model time machine and asks one of them to press a tiny lever on the model. The device disappears, validating his claim, but his friends remain unconvinced; their reactions vary from curiosity to frank dismissal.
George bids his guests a good evening, then heads downstairs where his full-size time machine awaits. He presses a lever and moves forward through time 17 years into the future to September 15, 1917. He meets Filby's son, James, who tells him of Filby's death in a war. Saddened, he resumes his journey, stopping on June 19, 1940 during The Blitz, finding himself in the midst of "a new war"; George resumes his journey and his house is hit by a bomb and is destroyed. George stops on August 19, 1966 finding his neighborhood now part of a futuristic metropolis. People hurry into a nearby fallout shelter amid the blare of air raid sirens. An elderly James Filby urges George to immediately take cover. Moments later, a nuclear explosion destroys London, causing a volcanic eruption around him. George narrowly makes it back to his machine and continues his journey forward as the lava rapidly rises, cools, and hardens, trapping him inside. He travels much farther into the future until the lava erodes away, revealing a lush, green, unspoiled landscape.
Output (English): How does David die?
