Problem: Red, blue, and white are also the Pan-Slavic colors adopted by the Slavic solidarity movement of the late nineteenth century. Initially these were the colors of the Russian flag; as the Slavic movement grew, they were adopted by other Slavic peoples including Slovaks, Slovenes, and Serbs. The flags of the Czech Republic and Poland use red for historic heraldic reasons (see Coat of arms of Poland and Coat of arms of the Czech Republic) & not due to Pan-Slavic connotations. In 2004 Georgia adopted a new white flag, which consists of four small and one big red cross in the middle touching all four sides.
Why do Georgia and Poland use red on their flags?

In his dissent to the majority report of the Financial Crisis Inquiry Commission, American Enterprise Institute fellow Peter J. Wallison stated his belief that the roots of the financial crisis can be traced directly and primarily to affordable housing policies initiated by HUD in the 1990s and to massive risky loan purchases by government-sponsored entities Fannie Mae and Freddie Mac. Later, based upon information in the SEC's December 2011 securities fraud case against 6 ex-executives of Fannie and Freddie, Peter Wallison and Edward Pinto estimated that, in 2008, Fannie and Freddie held 13 million substandard loans totaling over $2 trillion.
How many estimated substandard loans did Fannie and Freddie have in 2008? 
A: 13 million


Context and question: The most popular alcoholic drink in Switzerland is wine. Switzerland is notable for the variety of grapes grown because of the large variations in terroirs, with their specific mixes of soil, air, altitude and light. Swiss wine is produced mainly in Valais, Vaud (Lavaux), Geneva and Ticino, with a small majority of white wines. Vineyards have been cultivated in Switzerland since the Roman era, even though certain traces can be found of a more ancient origin. The most widespread varieties are the Chasselas (called Fendant in Valais) and Pinot noir. The Merlot is the main variety produced in Ticino.
When were vineyards first cultivated in Switzerland?
Answer: Roman era


Question: The prevalence of phantom pain in upper limb amputees is nearly 82%, and in lower limb amputees is 54%. One study found that eight days after amputation, 72 percent of patients had phantom limb pain, and six months later, 65 percent reported it. Some amputees experience continuous pain that varies in intensity or quality; others experience several bouts a day, or it may occur only once every week or two. It is often described as shooting, crushing, burning or cramping. If the pain is continuous for a long period, parts of the intact body may become sensitized, so that touching them evokes pain in the phantom limb, or phantom limb pain may accompany urination or defecation.
Is there an answer to this question: What do 54% of upper limb amputees experience? 

Answer: unanswerable


QUES: The term "house music" is said to have originated from a Chicago club called The Warehouse, which existed from 1977 to 1983. Clubbers to The Warehouse were primarily black and gay, who came to dance to music played by the club's resident DJ Frankie Knuckles, whom fans refer to as the "godfather of house". After the Warehouse closed in 1983, the crowds went to Knuckles' new club, The Power Plant. In the Channel 4 documentary Pump Up The Volume, Knuckles remarks that the first time he heard the term "house music" was upon seeing "we play house music" on a sign in the window of a bar on Chicago's South Side. One of the people in the car with him joked, "you know, that's the kind of music you play down at the Warehouse!", and then everybody laughed. South-Side Chicago DJ Leonard "Remix" Roy, in self-published statements, claims he put such a sign in a tavern window because it was where he played music that one might find in one's home; in his case, it referred to his mother's soul & disco records, which he worked into his sets. Farley Jackmaster Funk was quoted as saying "In 1982, I was DJing at a club called The Playground and there was this kid named Leonard 'Remix' Roy who was a DJ at a rival club called The Rink. He came over to my club one night, and into the DJ booth and said to me, 'I've got the gimmick that's gonna take all the people out of your club and into mine – it's called House music.' Now, where he got that name from or what made him think of it I don't know, so the answer lies with him."
