Problem: Please answer a question about the following article about Uranium:
Many contemporary uses of uranium exploit its unique nuclear properties. Uranium-235 has the distinction of being the only naturally occurring fissile isotope. Uranium-238 is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239 in a nuclear reactor. Another fissile isotope, uranium-233, can be produced from natural thorium and is also important in nuclear technology. While uranium-238 has a small probability for spontaneous fission or even induced fission with fast neutrons, uranium-235 and to a lesser degree uranium-233 have a much higher fission cross-section for slow neutrons. In sufficient concentration, these isotopes maintain a sustained nuclear chain reaction. This generates the heat in nuclear power reactors, and produces the fissile material for nuclear weapons. Depleted uranium (238U) is used in kinetic energy penetrators and armor plating.
What can be turned into plutonium-239 in a nuclear reactor?
A: Uranium-238
Problem: Please answer a question about the following article about Marvel Comics:
In late 1994, Marvel acquired the comic book distributor Heroes World Distribution to use as its own exclusive distributor. As the industry's other major publishers made exclusive distribution deals with other companies, the ripple effect resulted in the survival of only one other major distributor in North America, Diamond Comic Distributors Inc. In early 1997, when Marvel's Heroes World endeavor failed, Diamond also forged an exclusive deal with Marvelgiving the company its own section of its comics catalog Previews.
When did Marvel purchase this distribution network?
A: 1994
Problem: Please answer a question about the following article about United States Army:
Currently, the army is divided into the Regular Army, the Army Reserve, and the Army National Guard. The army is also divided into major branches such as Air Defense Artillery, Infantry, Aviation, Signal Corps, Corps of Engineers, and Armor. Before 1903 members of the National Guard were considered state soldiers unless federalized (i.e., activated) by the President. Since the Militia Act of 1903 all National Guard soldiers have held dual status: as National Guardsmen under the authority of the governor of their state or territory and, when activated, as a reserve of the U.S. Army under the authority of the President.
What were National Guard members considered before 1903?
A: state soldiers
Problem: Please answer a question about the following article about Near East:
The term "Near and Middle East," held the stage for a few years before World War I. It proved to be less acceptable to a colonial point of view that saw the entire region as one. In 1916 Captain T.C. Fowle, 40th Pathans (troops of British India), wrote of a trip he had taken from Karachi to Syria just before the war. The book does not contain a single instance of "Near East." Instead, the entire region is considered "the Middle East." The formerly Near Eastern sections of his trip are now "Turkish" and not Ottoman.
Who were the 40th Pathans?
A:
(troops of British India
