Input: Read this: At the beginning of World War I, East Prussia became a theatre of war when the Russian Empire invaded the country. The Russian Army encountered at first little resistance because the bulk of the German Army had been directed towards the Western Front according to the Schlieffen Plan. Despite early success and the capture of the towns of Rastenburg and Gumbinnen, in the Battle of Tannenberg in 1914 and the Second Battle of the Masurian Lakes in 1915, the Russians were decisively defeated and forced to retreat. The Russians were followed by the German Army advancing into Russian territory.
Question: In what year was the First Battle of the Masurian Lakes?

Output: unanswerable

QUES: According to the American National Standards Institute, pitch is the auditory attribute of sound according to which sounds can be ordered on a scale from low to high. Since pitch is such a close proxy for frequency, it is almost entirely determined by how quickly the sound wave is making the air vibrate and has almost nothing to do with the intensity, or amplitude, of the wave. That is, "high" pitch means very rapid oscillation, and "low" pitch corresponds to slower oscillation. Despite that, the idiom relating vertical height to sound pitch is shared by most languages. At least in English, it is just one of many deep conceptual metaphors that involve up/down. The exact etymological history of the musical sense of high and low pitch is still unclear. There is evidence that humans do actually perceive that the source of a sound is slightly higher or lower in vertical space when the sound frequency is increased or decreased.

Pitch is a close proxy for what?
What is the answer?
ANS: frequency

QUES: In central portions of the U.S., tornadoes are more common than anywhere else on Earth and touch down most commonly in the spring and summer. Deadly and destructive hurricanes occur almost every year along the Atlantic seaboard and the Gulf of Mexico. The Appalachian region and the Midwest experience the worst floods, though virtually no area in the U.S. is immune to flooding. The Southwest has the worst droughts; one is thought to have lasted over 500 years and to have hurt Ancestral Pueblo peoples. The West is affected by large wildfires each year.
During which seasons are tornados most common?

ANS: spring and summer

Roosevelt Boulevard and the Roosevelt Expressway (U.S. 1) connect Northeast Philadelphia with Center City. Woodhaven Road (Route 63), built in 1966, and Cottman Avenue (Route 73) serve the neighborhoods of Northeast Philadelphia, running between Interstate 95 and the Roosevelt Boulevard (U.S. 1). The Fort Washington Expressway (Route 309) extends north from the city's northern border, serving Montgomery County and Bucks County. U.S. 30, extending east-west from West Philadelphia to Lancaster, is known as Lancaster Avenue throughout most of the city and through the adjacent Main Line suburbs.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is another name for The Fort Washington Expressway?
Ah, so.. Route 309

Question: Groups share a fundamental kinship with the notion of symmetry. For example, a symmetry group encodes symmetry features of a geometrical object: the group consists of the set of transformations that leave the object unchanged and the operation of combining two such transformations by performing one after the other. Lie groups are the symmetry groups used in the Standard Model of particle physics; Point groups are used to help understand symmetry phenomena in molecular chemistry; and Poincare groups can express the physical symmetry underlying special relativity.
Try to answer this question if possible: What are the symmetry groups utilized as a part of the Standard Model particle physics?
Answer: Lie groups

Context and question: The 1910 election saw 42 Labour MPs elected to the House of Commons, a significant victory since, a year before the election, the House of Lords had passed the Osborne judgment ruling that Trades Unions in the United Kingdom could no longer donate money to fund the election campaigns and wages of Labour MPs. The governing Liberals were unwilling to repeal this judicial decision with primary legislation. The height of Liberal compromise was to introduce a wage for Members of Parliament to remove the need to involve the Trade Unions. By 1913, faced with the opposition of the largest Trades Unions, the Liberal government passed the Trade Disputes Act to allow Trade Unions to fund Labour MPs once more.
Who could no longer fund the wages of Liberal MPs?
Answer:
unanswerable
