A:After evaluating the engineering mock-ups and the full-scale wooden mock-up in February 1956, the RCAF demanded additional changes, selecting the advanced RCA-Victor "Astra" fire-control system firing the equally advanced United States Navy Sparrow II in place of the MX-1179 and Falcon combination. Avro vocally objected on the grounds that neither of these were even in testing at that point, whereas both the MX-1179 and Falcon were almost ready for production and would have been nearly as effective for "a very large saving in cost". The Astra proved to be problematic as the system ran into a lengthy period of delays, and when the USN cancelled the Sparrow II in 1956, Canadair was quickly brought in to continue the Sparrow program in Canada, although they expressed grave concerns about the project as well and the move added yet more expense. B:In February 1956, is it likely that blueprints had been finalized for the MX-1179? Answer: crop
A:The world population of Arctic foxes is thus not endangered, but two Arctic fox subpopulations are. One is on Medny Island (Commander Islands, Russia), which was reduced by some 85–90%, to around 90 animals, as a result of mange caused by an ear tick introduced by dogs in the 1970s. The population is currently under treatment with antiparasitic drugs, but the result is still yet to be seen. B:Would a scientist working with the Arctic foxes on Medny Island be able to give you an accurate estimate of how many will be alive in one year? Answer: resumes

A:The world population of Arctic foxes is thus not endangered, but two Arctic fox subpopulations are. One is on Medny Island (Commander Islands, Russia), which was reduced by a large percent, to a small number of animals, as a result of mange caused by an ear tick introduced by dogs in the 1970s. The uncertain population is currently under treatment with antiparasitic drugs, and the result is certain.
