The problem: Answer a question about this article:
To be considered 'enriched', the uranium-235 fraction should be between 3% and 5%. This process produces huge quantities of uranium that is depleted of uranium-235 and with a correspondingly increased fraction of uranium-238, called depleted uranium or 'DU'. To be considered 'depleted', the uranium-235 isotope concentration should be no more than 0.3%. The price of uranium has risen since 2001, so enrichment tailings containing more than 0.35% uranium-235 are being considered for re-enrichment, driving the price of depleted uranium hexafluoride above $130 per kilogram in July 2007 from $5 in 2001.
Between what percent fraction range of uranium-235 is uranium regarded as enriched?
****
The answer: 3% and 5%

Problem: Please answer a question about the following article about Xbox 360:
The Xbox 360's original graphical user interface was the Xbox 360 Dashboard; a tabbed interface that featured five "Blades" (formerly four blades), and was designed by AKQA and Audiobrain. It could be launched automatically when the console booted without a disc in it, or when the disc tray was ejected, but the user had the option to select what the console does if a game is in the tray on start up, or if inserted when already on. A simplified version of it was also accessible at any time via the Xbox Guide button on the gamepad. This simplified version showed the user's gamercard, Xbox Live messages and friends list. It also allowed for personal and music settings, in addition to voice or video chats, or returning to the Xbox Dashboard from the game.
The tabs on the user interface were called what?
A: Blades

On 30 September 1915, troops of the Serbian Army observed three enemy aircraft approaching Kragujevac. Soldiers shot at them with shotguns and machine-guns but failed to prevent them from dropping 45 bombs over the city, hitting military installations, the railway station and many other, mostly civilian, targets in the city. During the bombing raid, private Radoje Ljutovac fired his cannon at the enemy aircraft and successfully shot one down. It crashed in the city and both pilots died from their injuries. The cannon Ljutovac used was not designed as an anti-aircraft gun, it was a slightly modified Turkish cannon captured during the First Balkan War in 1912. This was the first occasion in military history that a military aircraft was shot down with ground-to-air fire.

How many bombs did the three aircraft drop on the city?
Answer: 45

Problem: Catholic missionary Father A. Erdland, from the Sacred Heart Jesu Society based in Hiltrup, Germany, lived on Jaluit from around 1904 to 1914. He was very interested in the islands and conducted considerable research on the Marshallese culture and language. He published a 376-page monograph on the islands in 1914. Father H. Linckens, another missionary from the Sacred Heart of Jesu Society visited the Marshall Islands in 1904 and 1911 for several weeks. He published a small work in 1912 about the Catholic mission activities and the people of the Marshall Islands.
In what year did Father Erdland leave the Marshall Islands?
The answer is the following: 1914

The black-body problem was revisited in 1905, when Rayleigh and Jeans (on the one hand) and Einstein (on the other hand) independently proved that classical electromagnetism could never account for the observed spectrum. These proofs are commonly known as the "ultraviolet catastrophe", a name coined by Paul Ehrenfest in 1911. They contributed greatly (along with Einstein's work on the photoelectric effect) to convincing physicists that Planck's postulate of quantized energy levels was more than a mere mathematical formalism. The very first Solvay Conference in 1911 was devoted to "the theory of radiation and quanta". Max Planck received the 1918 Nobel Prize in Physics "in recognition of the services he rendered to the advancement of Physics by his discovery of energy quanta".
When was the first Solvay Conference held?
1911

Here is a question about this article: On 11 October 1951, the Wafd government abrogated the 1936 Anglo-Egyptian Treaty, which had given the British control over the Suez Canal until 1956. The popularity of this move, as well as that of government-sponsored guerrilla attacks against the British, put pressure on Nasser to act. According to Sadat, Nasser decided to wage "a large scale assassination campaign". In January 1952, he and Hassan Ibrahim attempted to kill the royalist general Hussein Sirri Amer by firing their submachine guns at his car as he drove through the streets of Cairo. Instead of killing the general, the attackers wounded an innocent female passerby. Nasser recalled that her wails "haunted" him and firmly dissuaded him from undertaking similar actions in the future.
What is the answer to this question: Who did Nasser's group try to assassinate?
****
So...
Hussein Sirri Amer
