Q: Question: "How were the guns aimed to score a hit on the first try?"  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:
A: a centralised control system

Q: Question: "Zinc is added to pesticides by way of?"  Context: "Zinc deficiency is crop plants' most common micronutrient deficiency; it is particularly common in high-pH soils. Zinc-deficient soil is cultivated in the cropland of about half of Turkey and India, a third of China, and most of Western Australia, and substantial responses to zinc fertilization have been reported in these areas. Plants that grow in soils that are zinc-deficient are more susceptible to disease. Zinc is primarily added to the soil through the weathering of rocks, but humans have added zinc through fossil fuel combustion, mine waste, phosphate fertilizers, pesticide (zinc phosphide), limestone, manure, sewage sludge, and particles from galvanized surfaces. Excess zinc is toxic to plants, although zinc toxicity is far less widespread."  Answer:
A: humans

Q: Question: "Were more Greek or Turkish Cypriots displaced by the Turkish invasion of Cyprus?"  Context: "Cyprus was placed under British administration based on Cyprus Convention in 1878 and formally annexed by Britain in 1914. Even though Turkish Cypriots made up only 18% of the population, the partition of Cyprus and creation of a Turkish state in the north became a policy of Turkish Cypriot leaders and Turkey in the 1950s. Turkish leaders for a period advocated the annexation of Cyprus to Turkey as Cyprus was considered an "extension of Anatolia" by them; while since the 19th century, the majority Greek Cypriot population and its Orthodox church had been pursuing union with Greece, which became a Greek national policy in the 1950s. Following nationalist violence in the 1950s, Cyprus was granted independence in 1960. In 1963, the 11-year intercommunal violence between Greek Cypriots and Turkish Cypriots started, which displaced more than 25,000 Turkish Cypriots and brought the end of Turkish Cypriot representation in the republic. On 15 July 1974, a coup d'état was staged by Greek Cypriot nationalists and elements of the Greek military junta in an attempt at enosis, the incorporation of Cyprus into Greece. This action precipitated the Turkish invasion of Cyprus, which led to the capture of the present-day territory of Northern Cyprus the following month, after a ceasefire collapsed, and the displacement of over 150,000 Greek Cypriots and 50,000 Turkish Cypriots. A separate Turkish Cypriot state in the north was established in 1983. These events and the resulting political situation are matters of a continuing dispute."  Answer:
A: Greek Cypriots

Q: Question: "If children are raised Ashkenazi, what group is the woman from?"  Context: "In this respect, the counterpart of Ashkenazi is Sephardic, since most non-Ashkenazi Orthodox Jews follow Sephardic rabbinical authorities, whether or not they are ethnically Sephardic. By tradition, a Sephardic or Mizrahi woman who marries into an Orthodox or Haredi Ashkenazi Jewish family raises her children to be Ashkenazi Jews; conversely an Ashkenazi woman who marries a Sephardi or Mizrahi man is expected to take on Sephardic practice and the children inherit a Sephardic identity, though in practice many families compromise. A convert generally follows the practice of the beth din that converted him or her. With the integration of Jews from around the world in Israel, North America, and other places, the religious definition of an Ashkenazi Jew is blurring, especially outside Orthodox Judaism."  Answer:
A:
By tradition, a Sephardic or Mizrahi woman who marries into an Orthodox or Haredi
