Problem: Given the question: Question: "How did the guns function?" Context: "After the Dambusters raid in 1943 an entirely new system was developed that was required to knock down any low-flying aircraft with a single hit. The first attempt to produce such a system used a 50 mm gun, but this proved inaccurate and a new 55 mm gun replaced it. The system used a centralised control system including both search and targeting radar, which calculated the aim point for the guns after considering windage and ballistics, and then sent electrical commands to the guns, which used hydraulics to point themselves at high speeds. Operators simply fed the guns and selected the targets. This system, modern even by today's standards, was in late development when the war ended." Answer:

However, this is not in common use. The most complex character that can be input using the Microsoft New Phonetic IME 2002a for traditional Chinese is (da, "the appearance of a dragon flying"). It is composed of the dragon radical represented three times, for a total of 16 3 = 48 strokes. Among the most complex characters in modern dictionaries and also in frequent modern use are (yu, "to implore"), with 32 strokes; (yu, "luxuriant, lush; gloomy"), with 29 strokes, as in (youyu, "depressed"); (yan, "colorful"), with 28 strokes; and (xin, "quarrel"), with 25 strokes, as in (tiaoxin, "to pick a fight"). Also in occasional modern use is (xian "fresh"; variant of xian) with 33 strokes." Answer:

Q: Question: "The past act of formally puting an end to a system, practice, or institution, such as slavery is called?" Context: "Debate remained limited, and major decisions regarding the economy and defence were avoided or dealt with cursorily; the GPC largely remained "a rubber stamp" for Gaddafi's policies. On rare occasions, the GPC opposed Gaddafi's suggestions, sometimes successfully; notably, when Gaddafi called on primary schools to be abolished, believing that home schooling was healthier for children, the GPC rejected the idea. In other instances, Gaddafi pushed through laws without the GPC's support, such as when he desired to allow women into the armed forces. Gaddafi proclaimed that the People's Congresses provided for Libya's every political need, rendering other political organizations unnecessary; all non-authorized groups, including political parties, professional associations, independent trade unions and women's groups, were banned." Answer:
A: abolished
