Greece played a peripheral role in the war. When Russia attacked the Ottoman Empire in 1853, King Otto of Greece saw an opportunity to expand North and South into Ottoman areas that had large Greek Christian majorities. However, Greece did not coordinate its plans with Russia, did not declare war, and received no outside military or financial support. Greece, an Orthodox nation, had considerable support in Russia, but the Russian government decided it was too dangerous to help Greece expand its holdings.:32–40 When the Russians invaded the Principalities, the Ottoman forces were tied down so Greece invaded Thessaly and Epirus. To block further Greek moves, the British and French occupied the main Greek port at Piraeus from April 1854 to February 1857, and effectively neutralized the Greek army. Greeks, gambling on a Russian victory, incited the large-scale Epirus Revolt of 1854 as well as uprisings in Crete. The insurrections were failures that were easily crushed by the Ottoman army. Greece was not invited to the peace conference and made no gains out of the war.:139 The frustrated Greek leadership blamed the King for failing to take advantage of the situation; his popularity plunged and he was later forced to abdicate.

Who stirred up the Epirus Revolt of 1854?
Answer: Greeks


Problem: The Sumerians were a non-Semitic caucasoid people, and spoke a language isolate; a number of linguists believed they could detect a substrate language beneath Sumerian, because names of some of Sumer's major cities are not Sumerian, revealing influences of earlier inhabitants. However, the archaeological record shows clear uninterrupted cultural continuity from the time of the early Ubaid period (5300 – 4700 BC C-14) settlements in southern Mesopotamia. The Sumerian people who settled here farmed the lands in this region that were made fertile by silt deposited by the Tigris and the Euphrates rivers.
Why were the lands in the region the Sumerian people settled fertile?
The answer is the following: silt deposited by the Tigris and the Euphrates rivers


In September 1997, during the process of revision of racial categories previously declared by OMB directive no. 15, the American Anthropological Association (AAA) recommended that OMB combine the "race" and "ethnicity" categories into one question to appear as "race/ethnicity" for the 2000 US Census. The Interagency Committee agreed, stating that "race" and "ethnicity" were not sufficiently defined and "that many respondents conceptualize 'race' and 'ethnicity' as one in the same  [sic] underscor[ing] the need to consolidate these terms into one category, using a term that is more meaningful to the American people."
In what year are or racial categories first revised for the 2000 U.S. Census?
1997


Input: Brain
Brain tissue consumes a large amount of energy in proportion to its volume, so large brains place severe metabolic demands on animals. The need to limit body weight in order, for example, to fly, has apparently led to selection for a reduction of brain size in some species, such as bats. Most of the brain's energy consumption goes into sustaining the electric charge (membrane potential) of neurons. Most vertebrate species devote between 2% and 8% of basal metabolism to the brain. In primates, however, the percentage is much higher—in humans it rises to 20–25%. The energy consumption of the brain does not vary greatly over time, but active regions of the cerebral cortex consume somewhat more energy than inactive regions; this forms the basis for the functional brain imaging methods PET, fMRI, and NIRS. The brain typically gets most of its energy from oxygen-dependent metabolism of glucose (i.e., blood sugar), but ketones provide a major alternative source, together with contributions from medium chain fatty acids (caprylic and heptanoic acids), lactate, acetate, and possibly amino acids.

Other sources than glucose that provide energy to the brain are what?
Output: ketones


Input: Article: Beginning with the advent of beat match DJing, in which Bronx DJs (Disc Jockeys) including Grandmaster Flash, Afrika Bambaataa and DJ Kool Herc extended the breaks of funk records, a major new musical genre emerged that sought to isolate the percussion breaks of hit funk, disco and soul songs. As hip hop's popularity grew, performers began speaking ("rapping") in sync with the beats, and became known as MCs or emcees. The Herculoids, made up of Herc, Coke La Rock, and DJ Clark Kent, were the earliest to gain major fame. The Bronx is referred to in hip-hop slang as "The Boogie Down Bronx", or just "The Boogie Down". This was hip-hop pioneer KRS-One's inspiration for his thought provoking group BDP, or Boogie Down Productions, which included DJ Scott La Rock. Newer hip hop artists from the Bronx include Big Pun, Lord Toriq and Peter Gunz, Camp Lo, Swizz Beatz, Drag-On, Fat Joe, Terror Squad and Corey Gunz.

Now answer this question: What is 'The Boogie Down'?

Output: The Bronx


Problem: Argentine activists told a news conference that they would not try to snuff out the torch's flame as demonstrators had in Paris and London. "I want to announce that we will not put out the Olympic torch," said pro-Tibet activist Jorge Carcavallo. "We'll be carrying out surprise actions throughout the city of Buenos Aires, but all of these will be peaceful." Among other activities, protesters organized an alternative march that went from the Obelisk to the city hall, featuring their own "Human Rights Torch." A giant banner reading "Free Tibet" was also displayed on the torch route. According to a representative from the NGO 'Human Rights Torch Relay', their objective was to "show the contradiction between the Olympic Games and the presence of widespread human rights violations in China"
Where did the other march travel form and to?
The answer is the following:
Obelisk to the city hall
