Context and question: Signal Hill is a hill which overlooks the city of St. John's. It is the location of Cabot Tower which was built in 1897 to commemorate the 400th anniversary of John Cabot's discovery of Newfoundland, and Queen Victoria's Diamond Jubilee. The first transatlantic wireless transmission was received here by Guglielmo Marconi on 12 December 1901. Today, Signal Hill is a National Historic Site of Canada and remains incredibly popular amongst tourists and locals alike; 97% of all tourists to St. John's visit Signal Hill. Amongst its popular attractions are the Signal Hill Tattoo, showcasing the Royal Newfoundland Regiment of foot, c. 1795, and the North Head Trail which grants an impressive view of the Atlantic Ocean and the surrounding coast.
 Who recieved the first transatlantic wireless transmission?
Answer: Guglielmo Marconi
Context and question: Canadian bitumen does not differ substantially from oils such as Venezuelan extra-heavy and Mexican heavy oil in chemical composition, and the real difficulty is moving the extremely viscous bitumen through oil pipelines to the refinery. Many modern oil refineries are extremely sophisticated and can process non-upgraded bitumen directly into products such as gasoline, diesel fuel, and refined asphalt without any preprocessing. This is particularly common in areas such as the US Gulf coast, where refineries were designed to process Venezuelan and Mexican oil, and in areas such as the US Midwest where refineries were rebuilt to process heavy oil as domestic light oil production declined. Given the choice, such heavy oil refineries usually prefer to buy bitumen rather than synthetic oil because the cost is lower, and in some cases because they prefer to produce more diesel fuel and less gasoline. By 2015 Canadian production and exports of non-upgraded bitumen exceeded that of synthetic crude oil at over 1.3 million barrels (210×10^3 m3) per day, of which about 65% was exported to the United States.
Other than Venezuelan-light oil, what type of oil does Canadian bitumen not differ greatly from?
