Input: Read this: As the Kulluk oil rig was being towed to the American state of Washington to be serviced in preparation for the 2013 drilling season, a winter storm on 27 December 2012 caused the towing crews, as well as the rescue service, to lose control of the situation. As of 1 January 2013, the Kulluk was grounded off the coast Sitkalidak Island, near the eastern end of Kodiak Island. Following the accident, a Fortune magazine contacted Larry McKinney, the executive director at the Harte Research Institute for Gulf of Mexico Studies at Texas A&M, and he explained that "A two-month delay in the Arctic is not a two-month delay ... A two-month delay could wipe out the entire drilling season."

Input: Read this: Most CBC television stations, including those in the major cities, are owned and operated by the CBC itself. CBC O&O stations operate as a mostly seamless national service with few deviations from the main network schedule, although there are some regional differences from time to time. For on-air identification, most CBC stations use the CBC brand rather than their call letters, not identifying themselves specifically until sign-on or sign-off (though some, like Toronto's CBLT, do not ID themselves at all except through PSIP). All CBC O&O stations have a standard call letter naming convention, in that the first two letters are "CB" (an ITU prefix allocated not to Canada, but to Chile) and the last letter is "T". Only the third letter varies from market to market; however, that letter is typically the same as the third letter of the CBC Radio One and CBC Radio 2 stations in the same market. An exception to this rule are the CBC North stations in Yellowknife, Whitehorse and Iqaluit, whose call signs begin with "CF" due to their historic association with the CBC's Frontier Coverage Package prior to the advent of microwave and satellite broadcasting.
Question: The CBC does not allow on air call letter identification with which of their stations?

Output: unanswerable

Input: Read this: The Bovington signal course's director reported that Gaddafi successfully overcame problems learning English, displaying a firm command of voice procedure. Noting that Gaddafi's favourite hobbies were reading and playing football, he thought him an "amusing officer, always cheerful, hard-working, and conscientious." Gaddafi disliked England, claiming British Army officers racially insulted him and finding it difficult adjusting to the country's culture; asserting his Arab identity in London, he walked around Piccadilly wearing traditional Libyan robes. He later related that while he travelled to England believing it more advanced than Libya, he returned home "more confident and proud of our values, ideals and social character."
Question: Where did Gaddafi's signal course take place?

Bovington
