Task: Question Generation
Input (English): Shuman built the world’s first solar thermal power station in Maadi, Egypt, between 1912 and 1913. Shuman’s plant used parabolic troughs to power a 45–52 kilowatts (60–70 hp) engine that pumped more than 22,000 litres (4,800 imp gal; 5,800 US gal) of water per minute from the Nile River to adjacent cotton fields.

In 1916 Shuman was quoted in the media advocating solar energy's utilization, saying:
Output (English): From what river did the engine pump water?
