Problem: Near East:

If the British Empire was now going to side with the Russian Empire, the Ottoman Empire had no choice but to cultivate a relationship with the Austro-Hungarian Empire, which was supported by the German Empire. In a few years these alignments became the Triple Entente and the Triple Alliance (already formed in 1882), which were in part a cause of World War I. By its end in 1918 three empires were gone, a fourth was about to fall to revolution, and two more, the British and French, were forced to yield in revolutions started under the aegis of their own ideologies.

The formation of the Triple Entente and the Triple Alliance partly caused what?
---
A: World War I

Problem: Leakage is equivalent to a resistor in parallel with the capacitor. Constant exposure to heat can cause dielectric breakdown and excessive leakage, a problem often seen in older vacuum tube circuits, particularly where oiled paper and foil capacitors were used. In many vacuum tube circuits, interstage coupling capacitors are used to conduct a varying signal from the plate of one tube to the grid circuit of the next stage. A leaky capacitor can cause the grid circuit voltage to be raised from its normal bias setting, causing excessive current or signal distortion in the downstream tube. In power amplifiers this can cause the plates to glow red, or current limiting resistors to overheat, even fail. Similar considerations apply to component fabricated solid-state (transistor) amplifiers, but owing to lower heat production and the use of modern polyester dielectric barriers this once-common problem has become relatively rare.
What sort of capacitors are used to carry a varying signal from the conductive plate of one tube to the grid circuit of the next stage?
---
Answer: interstage coupling capacitors

Key sources of income included 329.5 million from research grants and contracts (2011/12 313.9 million), 186.3 million from academic fees and support grants (2011/12 163.1 million), 168.9 million from Funding Council grants (2011/12 172.4 million) and 12.5 million from endowment and investment income (2011/12 8.1 million). During the 2012/13 financial year Imperial had a capital expenditure of 124 million (2011/12 152 million).
What was Imperial's total expenditure for the financial year that ended on the 31 July 2013?
A: 754.9 million

Context and question: With the rise of disco in the US and punk rock in the UK, hard rock's mainstream dominance was rivalled toward the later part of the decade. Disco appealed to a more diverse group of people and punk seemed to take over the rebellious role that hard rock once held. Early punk bands like The Ramones explicitly rebelled against the drum solos and extended guitar solos that characterised stadium rock, with almost all of their songs clocking in around two minutes with no guitar solos. However, new rock acts continued to emerge and record sales remained high into the 1980s. 1977 saw the debut and rise to stardom of Foreigner, who went on to release several platinum albums through to the mid-1980s. Midwestern groups like Kansas, REO Speedwagon and Styx helped further cement heavy rock in the Midwest as a form of stadium rock. In 1978, Van Halen emerged from the Los Angeles music scene with a sound based around the skills of lead guitarist Eddie Van Halen. He popularised a guitar-playing technique of two-handed hammer-ons and pull-offs called tapping, showcased on the song "Eruption" from the album Van Halen, which was highly influential in re-establishing hard rock as a popular genre after the punk and disco explosion, while also redefining and elevating the role of electric guitar.
What were three midwestern hard rock bands?
Answer: Kansas, REO Speedwagon and Styx

Question: San Diego was ranked as the 20th-safest city in America in 2013 by Business Insider. According to Forbes magazine, San Diego was the ninth-safest city in the top 10 list of safest cities in the U.S. in 2010. Like most major cities, San Diego had a declining crime rate from 1990 to 2000. Crime in San Diego increased in the early 2000s. In 2004, San Diego had the sixth lowest crime rate of any U.S. city with over half a million residents. From 2002 to 2006, the crime rate overall dropped 0.8%, though not evenly by category. While violent crime decreased 12.4% during this period, property crime increased 1.1%. Total property crimes per 100,000 people were lower than the national average in 2008.
Is there an answer to this question: What percentage did the crime rate in San Diego drop from 2002 to 2006?

Answer: 0.8%

Karl Marx published the Communist Manifesto in February 1848, with little attention. However, a few days later the French Revolution of 1848 broke out, which replaced the monarchy of Louis Philippe with the Second French Republic. In June 1848, Paris workers, disenchanted with the new government, built barricades and raised red flags. The new government called in the French Army to put down the uprising, the first of many such confrontations between the army and the new worker's movements in Europe.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who published the Communist Manifesto in 1884?
Ah, so..
unanswerable
