Question: Whose submarines, between the Germans and Soviets, were the Bermuda bases first used to look out for?, Context: Construction began in 1941 of two airbases consisting of 5.8 km2 (2.2 sq mi) of land, largely reclaimed from the sea. For many years, Bermuda's bases were used by US Air Force transport and refuelling aircraft and by US Navy aircraft patrolling the Atlantic for enemy submarines, first German and, later, Soviet. The principal installation, Kindley Air Force Base on the eastern coast, was transferred to the US Navy in 1970 and redesignated Naval Air Station Bermuda. As a naval air station, the base continued to host both transient and deployed USN and USAF aircraft, as well as transitioning or deployed Royal Air Force and Canadian Forces aircraft.

Answer: German


Question: l replaced?, Context: Many of the non-alphanumeric characters were positioned to correspond to their shifted position on typewriters; an important subtlety is that these were based on mechanical typewriters, not electric typewriters. Mechanical typewriters followed the standard set by the Remington No. 2 (1878), the first typewriter with a shift key, and the shifted values of 23456789- were "#$%_&'() –  early typewriters omitted 0 and 1, using O (capital letter o) and l (lowercase letter L) instead, but 1! and 0) pairs became standard once 0 and 1 became common. Thus, in ASCII !"#$% were placed in second column, rows 1–5, corresponding to the digits 1–5 in the adjacent column. The parentheses could not correspond to 9 and 0, however, because the place corresponding to 0 was taken by the space character. This was accommodated by removing _ (underscore) from 6 and shifting the remaining characters left, which corresponded to many European typewriters that placed the parentheses with 8 and 9. This discrepancy from typewriters led to bit-paired keyboards, notably the Teletype Model 33, which used the left-shifted layout corresponding to ASCII, not to traditional mechanical typewriters. Electric typewriters, notably the more recently introduced IBM Selectric (1961), used a somewhat different layout that has become standard on computers—​​following the IBM PC (1981), especially Model M (1984)—​​and thus shift values for symbols on modern keyboards do not correspond as closely to the ASCII table as earlier keyboards did. The /? pair also dates to the No. 2, and the ,< .> pairs were used on some keyboards (others, including the No. 2, did not shift , (comma) or . (full stop) so they could be used in uppercase without unshifting). However, ASCII split the ;: pair (dating to No. 2), and rearranged mathematical symbols (varied conventions, commonly -* =+) to :* ;+ -=.

Answer: 1


Question: What was John's empire in danger?, Context: After Richard's death on 6 April 1199 there were two potential claimants to the Angevin throne: John, whose claim rested on being the sole surviving son of Henry II, and young Arthur I of Brittany, who held a claim as the son of John's elder brother Geoffrey. Richard appears to have started to recognise John as his heir presumptive in the final years before his death, but the matter was not clear-cut and medieval law gave little guidance as to how the competing claims should be decided. With Norman law favouring John as the only surviving son of Henry II and Angevin law favouring Arthur as the only son of Henry's elder son, the matter rapidly became an open conflict. John was supported by the bulk of the English and Norman nobility and was crowned at Westminster, backed by his mother, Eleanor. Arthur was supported by the majority of the Breton, Maine and Anjou nobles and received the support of Philip II, who remained committed to breaking up the Angevin territories on the continent. With Arthur's army pressing up the Loire valley towards Angers and Philip's forces moving down the valley towards Tours, John's continental empire was in danger of being cut in two.

Answer:
Arthur's army pressing up the Loire valley towards Angers and Philip's forces moving down the valley towards Tours
