Problem: London:

The pilgrims in Geoffrey Chaucer's late 14th-century Canterbury Tales set out for Canterbury from London – specifically, from the Tabard inn, Southwark. William Shakespeare spent a large part of his life living and working in London; his contemporary Ben Jonson was also based there, and some of his work—most notably his play The Alchemist—was set in the city. A Journal of the Plague Year (1722) by Daniel Defoe is a fictionalisation of the events of the 1665 Great Plague. Later important depictions of London from the 19th and early 20th centuries are Dickens' novels, and Arthur Conan Doyle's Sherlock Holmes stories. Modern writers pervasively influenced by the city include Peter Ackroyd, author of a "biography" of London, and Iain Sinclair, who writes in the genre of psychogeography.

Arthur Conan Doyle brought to life what famous detective in a series of novels?
---
A: Sherlock Holmes


Problem: When aspirated consonants are doubled or geminated, the stop is held longer and then has an aspirated release. An aspirated affricate consists of a stop, fricative, and aspirated release. A doubled aspirated affricate has a longer hold in the stop portion and then has a release consisting of the fricative and aspiration.
What is comprised of a stop, fricative, and aspirated release?
---
Answer: An aspirated affricate


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In 1907, the newly established Board of Education found that greater capacity for higher technical education was needed and a proposal to merge the City and Guilds College, the Royal School of Mines and the Royal College of Science was approved and passed, creating The Imperial College of Science and Technology as a constituent college of the University of London. Imperial's Royal Charter, granted by Edward VII, was officially signed on 8 July 1907. The main campus of Imperial College was constructed beside the buildings of the Imperial Institute in South Kensington.
When was the charter signed for the University of London?
A: unanswerable


Context and question: U.S. submarines accounted for 56% of the Japanese merchantmen sunk; mines or aircraft destroyed most of the rest. US submariners also claimed 28% of Japanese warships destroyed. Furthermore, they played important reconnaissance roles, as at the battles of the Philippine Sea (June 1944) and Leyte Gulf (October 1944) (and, coincidentally,[clarification needed] at Midway in June 1942), when they gave accurate and timely warning of the approach of the Japanese fleet. Submarines also rescued hundreds of downed fliers, including future U.S. president George H.W. Bush.
What was one of the important roles submarine played in the war?
Answer: reconnaissance roles


Question: With the new stadium, Barcelona participated in the inaugural version of the Pyrenees Cup, which, at the time, consisted of the best teams of Languedoc, Midi and Aquitaine (Southern France), the Basque Country and Catalonia; all were former members of the Marca Hispanica region. The contest was the most prestigious in that era. From the inaugural year in 1910 to 1913, Barcelona won the competition four consecutive times. Carles Comamala played an integral part of the four-time champion, managing the side along with Amechazurra and Jack Greenwell. The latter became the club's first full-time coach in 1917. The last edition was held in 1914 in the city of Barcelona, which local rivals Espanyol won.
Is there an answer to this question: When was the last Pyrenees Cup played?

Answer: 1914


Problem: Light-emitting diode:

Since LED efficacy is inversely proportional to operating temperature, LED technology is well suited for supermarket freezer lighting. Because LEDs produce less waste heat than incandescent lamps, their use in freezers can save on refrigeration costs as well. However, they may be more susceptible to frost and snow buildup than incandescent lamps, so some LED lighting systems have been designed with an added heating circuit. Additionally, research has developed heat sink technologies that will transfer heat produced within the junction to appropriate areas of the light fixture.

LED efficacy is not inversely proportional to what?
---
A:
unanswerable
