Input: Read this: The city grew as the population did, coming up against the lake's waters. As the depth of the lake water fluctuated, Mexico City was subject to periodic flooding. A major labor draft, the desague, compelled thousands of Indians over the colonial period to work on infrastructure to prevent flooding. Floods were not only an inconvenience but also a health hazard, since during flood periods human waste polluted the city's streets. By draining the area, the mosquito population dropped as did the frequency of the diseases they spread. However, draining the wetlands also changed the habitat for fish and birds and the areas accessible for Indian cultivation close to the capital.
Question: What was the main problem with being so close to the lake?

Output: flooding

Input: Read this: For five consecutive seasons, starting in season seven, the title was given to a white male who plays the guitar a trend that Idol pundits call the "White guy with guitar" or "WGWG" factor. Just hours before the season eleven finale, where Phillip Phillips was named the winner, Richard Rushfield, author of the book American Idol: The Untold Story, said, "You have this alliance between young girls and grandmas and they see it, not necessarily as a contest to create a pop star competing on the contemporary radio, but as .... who's the nicest guy in a popularity contest," he says, "And that has led to this dynasty of four, and possibly now five, consecutive, affable, very nice, good-looking white boys."
Question: Who won season eleven of American Idol?

Output: Phillip Phillips

Input: Read this: The ban on figurative depiction was not taken so seriously by the Jews living in Byzantine Gaza. In 1966 remains of a synagogue were found in the ancient harbour area. Its mosaic floor depicts King David as Orpheus, identified by his name in Hebrew letters. Near him were lion cubs, a giraffe and a snake listening to him playing a lyre. A further portion of the floor was divided by medallions formed by vine leaves, each of which contains an animal: a lioness suckling her cub, a giraffe, peacocks, panthers, bears, a zebra and so on. The floor was paved in 508/509. It is very similar to that of the synagogue at Maon (Menois) and the Christian church at Shellal, suggesting that the same artist most probably worked at all three places.
Question: What is the central figure doing in the mosaic found in 1966?

Output:
playing a lyre
