Input: Read this: In Serbia, the Serbian language is the official one, while both Serbian and Croatian are official in the province of Vojvodina. A large Bosniak minority is present in the southwest region of Sandzak, but the "official recognition" of Bosnian language is moot. Bosnian is an optional course in 1st and 2nd grade of the elementary school, while it is also in official use in the municipality of Novi Pazar. However, its nomenclature is controversial, as there is incentive that it is referred to as "Bosniak" (bosnjacki) rather than "Bosnian" (bosanski) (see Bosnian language for details).
Question: Where is a large Serbian minority located?

Output: unanswerable

QUES: There are two levels of service provided a free service to civilians and licensed service to the Chinese government and military. The free civilian service has a 10-meter location-tracking accuracy, synchronizes clocks with an accuracy of 10 nanoseconds, and measures speeds to within 0.2 m/s. The restricted military service has a location accuracy of 10 centimetres, can be used for communication, and will supply information about the system status to the user. To date, the military service has been granted only to the People's Liberation Army and to the Military of Pakistan.

Aside from the licensed service to Japanese civilians, what is the other level of service provided?
What is the answer?
ANS: unanswerable

QUES: During a visit in 1885 English journalist George Augustus Henry Sala coined the phrase "Marvellous Melbourne", which stuck long into the twentieth century and is still used today by Melburnians. Growing building activity culminated in a "land boom" which, in 1888, reached a peak of speculative development fuelled by consumer confidence and escalating land value. As a result of the boom, large commercial buildings, coffee palaces, terrace housing and palatial mansions proliferated in the city. The establishment of a hydraulic facility in 1887 allowed for the local manufacture of elevators, resulting in the first construction of high-rise buildings; most notably the APA Building, amongst the world's tallest commercial buildings upon completion in 1889. This period also saw the expansion of a major radial rail-based transport network.
What did Melbourne's hydraulic facilities help create that spurred high-rise developments?

ANS: elevators

North Carolina became one of the English Thirteen Colonies and with the territory of South Carolina was originally known as the Province of Carolina. The northern and southern parts of the original province separated in 1729. Originally settled by small farmers, sometimes having a few slaves, who were oriented toward subsistence agriculture, the colony lacked cities or towns. Pirates menaced the coastal settlements, but by 1718 the pirates had been captured and killed. Growth was strong in the middle of the 18th century, as the economy attracted Scots-Irish, Quaker, English and German immigrants. The colonists generally supported the American Revolution, as the number of Loyalists was smaller than in some other colonies.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What people were a menace to the coastal areas of the Province of carolina?
Ah, so.. Pirates

Question: In response to the September 11 attacks, and as part of the Global War on Terror, U.S. and NATO forces invaded Afghanistan in October 2001, displacing the Taliban government. The U.S. Army also led the combined U.S. and allied invasion of Iraq in 2003. It served as the primary source for ground forces with its ability to sustain short and long-term deployment operations. In the following years the mission changed from conflict between regular militaries to counterinsurgency, resulting in the deaths of more than 4,000 U.S service members (as of March 2008) and injuries to thousands more. 23,813 insurgents were killed in Iraq between 20032011.
Try to answer this question if possible: Which country was liberated by the U.S. in October 2001?
Answer: unanswerable

QUES: Feynman attended Far Rockaway High School, a school in Far Rockaway, Queens also attended by fellow Nobel laureates Burton Richter and Baruch Samuel Blumberg. Upon starting high school, Feynman was quickly promoted into a higher math class. An unspecified school-administered IQ test estimated his IQ at 123high, but "merely respectable" according to biographer James Gleick. When he turned 15, he taught himself trigonometry, advanced algebra, infinite series, analytic geometry, and both differential and integral calculus. In high school he was developing the mathematical intuition behind his Taylor series of mathematical operators. Before entering college, he was experimenting with and deriving mathematical topics such as the half-derivative using his own notation.
What did Feynman derive only after college?
