Problem: Alps:

Glaciers pick up rocks and sediment with them as they flow. This causes erosion and the formation of valleys over time. The Inn valley is an example of a valley carved by glaciers during the ice ages with a typical terraced structure caused by erosion. Eroded rocks from the most recent ice age lie at the bottom of the valley while the top of the valley consists of erosion from earlier ice ages. Glacial valleys have characteristically steep walls (reliefs); valleys with lower reliefs and talus slopes are remnants of glacial troughs or previously infilled valleys. Moraines, piles of rock picked up during the movement of the glacier, accumulate at edges, center and the terminus of glaciers.

What are Moraines?
---
A: piles of rock picked up during the movement of the glacier


Problem: Former members Heather and Gary Botting compare the cultural paradigms of the religion to George Orwell's Nineteen Eighty-four, and Alan Rogerson describes the religion's leadership as totalitarian. Other critics charge that by disparaging individual decision-making, the religion's leaders cultivate a system of unquestioning obedience in which Witnesses abrogate all responsibility and rights over their personal lives. Critics also accuse the religion's leaders of exercising "intellectual dominance" over Witnesses, controlling information and creating "mental isolation", which former Governing Body member Raymond Franz argued were all elements of mind control.
What do former Jehovah's Witnesses members Heath and Gary Botting compare the culture of the religion to?

Answer: Orwell's Nineteen Eighty-four


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Spielberg was scheduled to shoot a $200 million adaptation of Daniel H. Wilson's novel Robopocalypse, adapted for the screen by Drew Goddard. The film would follow a global human war against a robot uprising about 15–20 years in the future. Like Lincoln, it was to be released by Disney in the United States and Fox overseas. It was set for release on April 25, 2014, with Anne Hathaway and Chris Hemsworth set to star, but Spielberg postponed production indefinitely in January 2013, just before it had been set to begin.
When was 'Robopocalypse' scheduled for release?
A: April 25, 2014


Context and question: There were serious scientific objections to the process of natural selection as the key mechanism of evolution, including Karl von Nägeli's insistence that a trivial characteristic with no adaptive advantage could not be developed by selection. Darwin conceded that these could be linked to adaptive characteristics. His estimate that the age of the Earth allowed gradual evolution was disputed by William Thomson (later awarded the title Lord Kelvin), who calculated that it had cooled in less than 100 million years. Darwin accepted blending inheritance, but Fleeming Jenkin calculated that as it mixed traits, natural selection could not accumulate useful traits. Darwin tried to meet these objections in the 5th edition. Mivart supported directed evolution, and compiled scientific and religious objections to natural selection. In response, Darwin made considerable changes to the sixth edition. The problems of the age of the Earth and heredity were only resolved in the 20th century.
When were the problems of the earth and heredity resolved?
Answer: in the 20th century


Question: The Métropole du Grand Paris, or Metropolis of Greater Paris, formally came into existence on January 1, 2016. It is an administrative structure for cooperation between the City of Paris and its nearest suburbs. It includes the City of Paris, plus the communes, or towns of the three departments of the inner suburbs; Hauts-de-Seine, Seine-Saint-Denis and Val-de-Marne; plus seven communes in the outer suburbs, including Argenteuil in Val d'Oise and Paray-Vieille-Poste in Essonne, which were added to include the major airports of Paris. The Metropole covers 814 square kilometers and has a population of 6.945 million persons.
Is there an answer to this question: What is the population of the metropole?

Answer: 6.945 million


Question: As in the Scheiner system, speeds were expressed in 'degrees'. Originally the sensitivity was written as a fraction with 'tenths' (for example "18/10° DIN"), where the resultant value 1.8 represented the relative base 10 logarithm of the speed. 'Tenths' were later abandoned with DIN 4512:1957-11, and the example above would be written as "18° DIN". The degree symbol was finally dropped with DIN 4512:1961-10. This revision also saw significant changes in the definition of film speeds in order to accommodate then-recent changes in the American ASA PH2.5-1960 standard, so that film speeds of black-and-white negative film effectively would become doubled, that is, a film previously marked as "18° DIN" would now be labeled as "21 DIN" without emulsion changes.
Is there an answer to this question: What unit was used in the DIN to express speeds? 

Answer:
degrees
