Input: Read this: In practice, culture referred to an elite ideal and was associated with such activities as art, classical music, and haute cuisine. As these forms were associated with urban life, "culture" was identified with "civilization" (from lat. civitas, city). Another facet of the Romantic movement was an interest in folklore, which led to identifying a "culture" among non-elites. This distinction is often characterized as that between high culture, namely that of the ruling social group, and low culture. In other words, the idea of "culture" that developed in Europe during the 18th and early 19th centuries reflected inequalities within European societies.
Question: When did the idea of "culture" stop in Europe?

Output: unanswerable

Input: Read this: On 28 April 2015, the Iranian navy seized the Marshall Island-flagged MV Maersk Tigris near the Strait of Hormuz. The ship had been chartered by Germany's Rickmers Ship Management, which stated that the ship contained no special cargo and no military weapons. The ship was reported to be under the control of the Iranian Revolutionary Guard according to the Pentagon. Tensions escallated in the region due to the intensifying of Saudi-led coalition attacks in Yemen. The Pentagon reported that the destroyer USS Farragut and a maritime reconnaissance aircraft were dispatched upon receiving a distress call from the ship Tigris and it was also reported that all 34 crew members were detained. US defense officials have said that they would review U.S. defense obligations to the Government of the Marshall Islands in the wake of recent events and also condemned the shots fired at the bridge as "inappropriate". It was reported in May 2015 that Tehran would release the ship after it paid a penalty.
Question: On what date did the Iranian Navy capture a Marshall Islands ship?

Output: 28 April 2015

Input: Read this: The most common forms of uranium oxide are triuranium octoxide (U
3O
8) and UO
2. Both oxide forms are solids that have low solubility in water and are relatively stable over a wide range of environmental conditions. Triuranium octoxide is (depending on conditions) the most stable compound of uranium and is the form most commonly found in nature. Uranium dioxide is the form in which uranium is most commonly used as a nuclear reactor fuel. At ambient temperatures, UO
2 will gradually convert to U
3O
8. Because of their stability, uranium oxides are generally considered the preferred chemical form for storage or disposal.
Question: In what form is uranium least often used as fuel for nuclear reactors?

Output: unanswerable

Input: Read this: Midway through the 19th century, the focus of geology shifted from description and classification to attempts to understand how the surface of the Earth had changed. The first comprehensive theories of mountain building were proposed during this period, as were the first modern theories of earthquakes and volcanoes. Louis Agassiz and others established the reality of continent-covering ice ages, and "fluvialists" like Andrew Crombie Ramsay argued that river valleys were formed, over millions of years by the rivers that flow through them. After the discovery of radioactivity, radiometric dating methods were developed, starting in the 20th century. Alfred Wegener's theory of "continental drift" was widely dismissed when he proposed it in the 1910s, but new data gathered in the 1950s and 1960s led to the theory of plate tectonics, which provided a plausible mechanism for it. Plate tectonics also provided a unified explanation for a wide range of seemingly unrelated geological phenomena. Since 1970 it has served as the unifying principle in geology.
Question: The idea of an ice-age that completely covered a continent was suggested by whom?

Output:
Louis Agassiz
