The development of flattop vessels produced the first large fleet ships. In 1918, HMS Argus became the world's first carrier capable of launching and recovering naval aircraft. As a result of the Washington Naval Treaty of 1922, which limited the construction of new heavy surface combat ships, most early aircraft carriers were conversions of ships that were laid down (or had served) as different ship types: cargo ships, cruisers, battlecruisers, or battleships. These conversions gave rise to the Lexington-class aircraft carriers (1927), Akagi and Courageous class. Specialist carrier evolution was well underway, with several navies ordering and building warships that were purposefully designed to function as aircraft carriers by the mid-1920s, resulting in the commissioning of ships such as Hōshō (1922), HMS Hermes (1924), and Béarn (1927). During World War II, these ships would become known as fleet carriers.[citation needed]
What did the Washington Naval Treaty of 1922 limit?
the construction of new heavy surface combat ships


Input: Anti-aircraft warfare
Although the firearms used by the infantry, particularly machine guns, can be used to engage low altitude air targets, on occasion with notable success, their effectiveness is generally limited and the muzzle flashes reveal infantry positions. Speed and altitude of modern jet aircraft limit target opportunities, and critical systems may be armored in aircraft designed for the ground attack role. Adaptations of the standard autocannon, originally intended for air-to-ground use, and heavier artillery systems were commonly used for most anti-aircraft gunnery, starting with standard pieces on new mountings, and evolving to specially designed guns with much higher performance prior to World War II.

Heavier artillery systems were typically used for what?
Output: most anti-aircraft gunnery


Input: Article: The softness of copper partly explains its high electrical conductivity (59.6×106 S/m) and thus also high thermal conductivity, which are the second highest (to silver) among pure metals at room temperature. This is because the resistivity to electron transport in metals at room temperature mostly originates from scattering of electrons on thermal vibrations of the lattice, which are relatively weak for a soft metal. The maximum permissible current density of copper in open air is approximately 3.1×106 A/m2 of cross-sectional area, above which it begins to heat excessively. As with other metals, if copper is placed against another metal, galvanic corrosion will occur.

Now answer this question: What is the maximum premissible current density in open air of copper?

Output: 3.1×106 A/m2


Article: Orontid Armenia formally passed to empire of Alexander the Great following his conquest of Persia. Alexander appointed an Orontid named Mithranes to govern Armenia. Armenia later became a vassal state of the Seleucid Empire, but it maintained a considerable degree of autonomy, retaining its native rulers. Towards the end 212 BC the country was divided into two kingdoms, Greater Armenia and Armenia Sophene including Commagene or Armenia Minor. The kingdoms became so independent from Seleucid control that Antiochus III the Great waged war on them during his reign and replaced their rulers.

Question: Orontid Armenia was given to Alexander the Great after he took control of what area?
Ans: Persia


Here is a question about this article: Hayek was one of the leading academic critics of collectivism in the 20th century. Hayek argued that all forms of collectivism (even those theoretically based on voluntary co-operation) could only be maintained by a central authority of some kind. In Hayek's view, the central role of the state should be to maintain the rule of law, with as little arbitrary intervention as possible. In his popular book, The Road to Serfdom (1944) and in subsequent academic works, Hayek argued that socialism required central economic planning and that such planning in turn leads towards totalitarianism.
What is the answer to this question: How did Hayek believe collectivism could be maintained?
****
So... a central authority


Article: Meanwhile, producer Joe Pasternak, who had been successfully producing light musicals with young sopranos for Universal's German subsidiary, repeated his formula in America. Teenage singer Deanna Durbin starred in Pasternak's first American film, Three Smart Girls (1936). The film was a box-office hit and reputedly restored the studio's solvency. The success of the film led Universal to offer her a contract, which for the first five years of her career produced her most successful pictures.

Question: Prior to his work in America, where was Joe Pasternak employed?
Ans:
Universal's German subsidiary
