Problem: Question: "What kind of time keeping system is used in Turkey?"  Context: "Prior to 1917, Turkey used the lunar Islamic calendar with the Hegira era for general purposes and the Julian calendar for fiscal purposes. The start of the fiscal year was eventually fixed at 1 March and the year number was roughly equivalent to the Hegira year (see Rumi calendar). As the solar year is longer than the lunar year this originally entailed the use of "escape years" every so often when the number of the fiscal year would jump. From 1 March 1917 the fiscal year became Gregorian, rather than Julian. On 1 January 1926 the use of the Gregorian calendar was extended to include use for general purposes and the number of the year became the same as in other countries."  Answer:

A: the Gregorian calendar


Problem: Question: "What was the final act by politicians that angered the plebeians before seceding?"  Context: "By 287 BC, the economic condition of the average plebeian had become poor. The problem appears to have centered around widespread indebtedness. The plebeians demanded relief, but the senators refused to address their situation. The result was the final plebeian secession. The plebeians seceded to the Janiculum hill. To end the secession, a dictator was appointed. The dictator passed a law (the Lex Hortensia), which ended the requirement that the patrician senators must agree before any bill could be considered by the Plebeian Council. This was not the first law to require that an act of the Plebeian Council have the full force of law. The Plebeian Council acquired this power during a modification to the original Valerian law in 449 BC. The significance of this law was in the fact that it robbed the patricians of their final weapon over the plebeians. The result was that control over the state fell, not onto the shoulders of voters, but to the new plebeian nobility."  Answer:

A: the senators refused to address their situation


Problem: Question: "Name a country where Cubism architecture is used."  Context: "The original Cubist architecture is very rare. There is only one country in the world where Cubism was really applied to architecture – namely Bohemia (today Czech Republic) and especially its capital, Prague. Czech architects were the first and only ones in the world to ever design original Cubist buildings. Cubist architecture flourished for the most part between 1910–1914, but the Cubist or Cubism-influenced buildings were also built after the World War I. After the war, the architectural style called Rondo-Cubism was developed in Prague fusing the Cubist architecture with round shapes."  Answer:

A: Bohemia


Problem: Question: "What is the median of the bills currently used?"  Context: "Currently printed denominations are $1, $2, $5, $10, $20, $50, and $100. Notes above the $100 denomination stopped being printed in 1946 and were officially withdrawn from circulation in 1969. These notes were used primarily in inter-bank transactions or by organized crime; it was the latter usage that prompted President Richard Nixon to issue an executive order in 1969 halting their use. With the advent of electronic banking, they became less necessary. Notes in denominations of $500, $1,000, $5,000, $10,000 and $100,000 were all produced at one time; see large denomination bills in U.S. currency for details. These notes are now collectors' items and are worth more than their face value to collectors."  Answer:

A:
