Problem: Hanover:

Hanover was founded in medieval times on the east bank of the River Leine. Its original name Honovere may mean "high (river)bank", though this is debated (cf. das Hohe Ufer). Hanover was a small village of ferrymen and fishermen that became a comparatively large town in the 13th century due to its position at a natural crossroads. As overland travel was relatively difficult, its position on the upper navigable reaches of the river helped it to grow by increasing trade. It was connected to the Hanseatic League city of Bremen by the Leine, and was situated near the southern edge of the wide North German Plain and north-west of the Harz mountains, so that east-west traffic such as mule trains passed through it. Hanover was thus a gateway to the Rhine, Ruhr and Saar river valleys, their industrial areas which grew up to the southwest and the plains regions to the east and north, for overland traffic skirting the Harz between the Low Countries and Saxony or Thuringia.

Problem: The gastronomic symbol of the region is undoubtedly the Choucroute, a local variety of Sauerkraut. The word Sauerkraut in Alsatian has the form surkrut, same as in other southwestern German dialects, and means "sour cabbage" as its Standard German equivalent. This word was included into the French language as choucroute. To make it, the cabbage is finely shredded, layered with salt and juniper and left to ferment in wooden barrels. Sauerkraut can be served with poultry, pork, sausage or even fish. Traditionally it is served with Strasbourg sausage or frankfurters, bacon, smoked pork or smoked Morteau or Montbeliard sausages, or a selection of other pork products. Served alongside are often roasted or steamed potatoes or dumplings.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
About 1150 species of fungi have been recorded from Antarctica, of which about 750 are non-lichen-forming and 400 are lichen-forming. Some of these species are cryptoendoliths as a result of evolution under extreme conditions, and have significantly contributed to shaping the impressive rock formations of the McMurdo Dry Valleys and surrounding mountain ridges. The apparently simple morphology, scarcely differentiated structures, metabolic systems and enzymes still active at very low temperatures, and reduced life cycles shown by such fungi make them particularly suited to harsh environments such as the McMurdo Dry Valleys. In particular, their thick-walled and strongly melanized cells make them resistant to UV light. Those features can also be observed in algae and cyanobacteria, suggesting that these are adaptations to the conditions prevailing in Antarctica. This has led to speculation that, if life ever occurred on Mars, it might have looked similar to Antarctic fungi such as Cryomyces minteri. Some of these fungi are also apparently endemic to Antarctica. Endemic Antarctic fungi also include certain dung-inhabiting species which have had to evolve in response to the double challenge of extreme cold while growing on dung, and the need to survive passage through the gut of warm-blooded animals.
Where were 750 lichen-forming fungi found?
A: unanswerable

Context and question: The poets generally associated with Cubism are Guillaume Apollinaire, Blaise Cendrars, Jean Cocteau, Max Jacob, Andre Salmon and Pierre Reverdy. As American poet Kenneth Rexroth explains, Cubism in poetry "is the conscious, deliberate dissociation and recombination of elements into a new artistic entity made self-sufficient by its rigorous architecture. This is quite different from the free association of the Surrealists and the combination of unconscious utterance and political nihilism of Dada." Nonetheless, the Cubist poets' influence on both Cubism and the later movements of Dada and Surrealism was profound; Louis Aragon, founding member of Surrealism, said that for Breton, Soupault, Eluard and himself, Reverdy was "our immediate elder, the exemplary poet." Though not as well remembered as the Cubist painters, these poets continue to influence and inspire; American poets John Ashbery and Ron Padgett have recently produced new translations of Reverdy's work. Wallace Stevens' "Thirteen Ways of Looking at a Blackbird" is also said to demonstrate how cubism's multiple perspectives can be translated into poetry.
What is the name of the american Poet who is associated with talking about the rigiorous architecture of Cubism?
Answer: Kenneth Rexroth

Question: The first scientific and literary journals were established during the Enlightenment. The first journal, the Parisian Journal des Scavans, appeared in 1665. However, it was not until 1682 that periodicals began to be more widely produced. French and Latin were the dominant languages of publication, but there was also a steady demand for material in German and Dutch. There was generally low demand for English publications on the Continent, which was echoed by England's similar lack of desire for French works. Languages commanding less of an international market such as Danish, Spanish and Portuguese found journal success more difficult, and more often than not, a more international language was used instead. French slowly took over Latin's status as the lingua franca of learned circles. This in turn gave precedence to the publishing industry in Holland, where the vast majority of these French language periodicals were produced.
Is there an answer to this question: During which movement were the first scientific and literary journals established?

Answer: the Enlightenment

Problem: Electric motor:

When optimally designed within a given core saturation constraint and for a given active current (i.e., torque current), voltage, pole-pair number, excitation frequency (i.e., synchronous speed), and air-gap flux density, all categories of electric motors or generators will exhibit virtually the same maximum continuous shaft torque (i.e., operating torque) within a given air-gap area with winding slots and back-iron depth, which determines the physical size of electromagnetic core. Some applications require bursts of torque beyond the maximum operating torque, such as short bursts of torque to accelerate an electric vehicle from standstill. Always limited by magnetic core saturation or safe operating temperature rise and voltage, the capacity for torque bursts beyond the maximum operating torque differs significantly between categories of electric motors or generators.

Whate decides the size of an electromagnetic core?

A:
air-gap area with winding slots and back-iron depth
