Problem: Today both the Papireto river and the Kemonia are covered up by buildings. However, the shape of the former watercourses can still be recognised today, because the streets that were built on them follow their shapes. Today the only waterway not drained yet is the Oreto river that divides the downtown of the city from the western uptown and the industrial districts. In the basins there were, though, many seasonal torrents that helped formed swampy plains, reclaimed during history; a good example of which can be found in the borough of Mondello.
What is the only remaining waterway in Palermo?
The answer is the following: Oreto river

Problem: Kurita's "Center Force" consisted of five battleships, 12 cruisers and 13 destroyers. It included the two largest battleships ever built: Yamato and Musashi. As they passed Palawan Island after midnight on 23 October the force was spotted, and U.S. submarines sank two cruisers. On 24 October, as Kurita's force entered the Sibuyan Sea, USS Intrepid and USS Cabot launched 260 planes, which scored hits on several ships. A second wave of planes scored many direct hits on Musashi. A third wave, from USS Enterprise and USS Franklin hit Musashi with 11 bombs and eight torpedoes. Kurita retreated but in the evening turned around to head for San Bernardino Strait. Musashi sank at about 19:30.
How many battleships were in Kurita's "Center Force"?
The answer is the following: five

Problem: The city is home to New Haven Promise, a scholarship funded by Yale University for students who meet the requirements. Students must be enrolled in a public high school (charters included) for four years, be a resident of the city during that time, carry a 3.0 cumulative grade-point average, have a 90-percent attendance rate and perform 40 hours of service to the city. The initiative was launched in 2010 and there are currently more than 500 Scholars enrolled in qualifying Connecticut colleges and universities. There are more than 60 cities in the country that have a Promise-type program for their students.
How many hours of community service must a student perform in order to be eligible for the New Haven Promise scholarship?
The answer is the following: 40 hours

Problem: Lothar Wolfgang Nordheim described von Neumann as the "fastest mind I ever met", and Jacob Bronowski wrote "He was the cleverest man I ever knew, without exception. He was a genius." George Pólya, whose lectures at ETH Zürich von Neumann attended as a student, said "Johnny was the only student I was ever afraid of. If in the course of a lecture I stated an unsolved problem, the chances were he'd come to me at the end of the lecture with the complete solution scribbled on a slip of paper." Halmos recounts a story told by Nicholas Metropolis, concerning the speed of von Neumann's calculations, when somebody asked von Neumann to solve the famous fly puzzle:
What did Jacob Bronowski think of von Neumann?
The answer is the following:
He was the cleverest man I ever knew, without exception. He was a genius.
