Article: Uranium metal reacts with almost all non-metal elements (with an exception of the noble gases) and their compounds, with reactivity increasing with temperature. Hydrochloric and nitric acids dissolve uranium, but non-oxidizing acids other than hydrochloric acid attack the element very slowly. When finely divided, it can react with cold water; in air, uranium metal becomes coated with a dark layer of uranium oxide. Uranium in ores is extracted chemically and converted into uranium dioxide or other chemical forms usable in industry.

Question: What is a notable form uranium ore is converted into after extraction?
Ans: uranium dioxide


Article: The European Central Bank had stepped up the buying of member nations debt. In response to the crisis of 2010, some proposals have surfaced for a collective European bond issue that would allow the central bank to purchase a European version of US Treasury bills. To make European sovereign debt assets more similar to a US Treasury, a collective guarantee of the member states' solvency would be necessary.[b] But the German government has resisted this proposal, and other analyses indicate that "the sickness of the euro" is due to the linkage between sovereign debt and failing national banking systems. If the European central bank were to deal directly with failing banking systems sovereign debt would not look as leveraged relative to national income in the financially weaker member states.

Question: Which country has been resistant to attempts to make the soverign debt assets more like the U.S. Treasury?
Ans: the German government


Article: Oklahoma City is on the I-35 Corridor and is one of the primary travel corridors into neighboring Texas and Mexico. Located in the Frontier Country region of the state, the city's northeast section lies in an ecological region known as the Cross Timbers. The city was founded during the Land Run of 1889, and grew to a population of over 10,000 within hours of its founding. The city was the scene of the April 19, 1995 bombing of the Alfred P. Murrah Federal Building, in which 168 people died. It was the deadliest terror attack in the history of the United States until the attacks of September 11, 2001, and remains the deadliest act of domestic terrorism in U.S. history.

Question: What was the name of the building involved in the bombing?
Ans: Alfred P. Murrah Federal Building


Article: TCM's film content has remained mostly uncut and uncolorized (with films natively filmed or post-produced in the format being those only ones presented in color), depending upon the original content of movies, particularly movies released after the 1968 implementation of the Motion Picture Association of America's ratings system and the concurrent disestablishment of the Motion Picture Production Code. Because of this, TCM is formatted similarly to a premium channel with certain films – particularly those made from the 1960s onward – sometimes featuring nudity, sexual content, violence and/or strong profanity; the network also features rating bumpers prior to the start of a program (most programs on TCM, especially films, are rated for content using the TV Parental Guidelines, in lieu of the MPAA's rating system).

Question: In what year did the Motion Picture Association of America introduce its rating system?
Ans:
1968
