Question: Extract the answer to the question from the following context. Question: How has production potential from the oil sands been increased? Context: Naturally occurring crude asphalt/bitumen impregnated in sedimentary rock is the prime feed stock for petroleum production from "Oil sands", currently under development in Alberta, Canada. Canada has most of the world's supply of natural asphalt/bitumen, covering 140,000 square kilometres (an area larger than England), giving it the second-largest proven oil reserves in the world. The Athabasca oil sands is the largest asphalt/bitumen deposit in Canada and the only one accessible to surface mining, although recent technological breakthroughs have resulted in deeper deposits becoming producible by in situ methods. Because of oil price increases after 2003, producing bitumen became highly profitable, but as a result of the decline after 2014 it became uneconomic to build new plants again. By 2014, Canadian crude asphalt/bitumen production averaged about 2.3 million barrels (370,000 m3) per day and was projected to rise to 4.4 million barrels (700,000 m3) per day by 2020. The total amount of crude asphalt/bitumen in Alberta which could be extracted is estimated to be about 310 billion barrels (50×10^9 m3), which at a rate of 4,400,000 barrels per day (700,000 m3/d) would last about 200 years.
Answer: recent technological breakthroughs

Question: Extract the answer to the question from the following context. Question: Who was Ducos? Context: Despite the failures in Egypt, Napoleon returned to a hero's welcome. He drew together an alliance with director Emmanuel Joseph Sieyès, his brother Lucien, speaker of the Council of Five Hundred Roger Ducos, director Joseph Fouché, and Talleyrand, and they overthrew the Directory by a coup d'état on 9 November 1799 ("the 18th Brumaire" according to the revolutionary calendar), closing down the council of five hundred. Napoleon became "first consul" for ten years, with two consuls appointed by him who had consultative voices only. His power was confirmed by the new "Constitution of the Year VIII", originally devised by Sieyès to give Napoleon a minor role, but rewritten by Napoleon, and accepted by direct popular vote (3,000,000 in favor, 1,567 opposed). The constitution preserved the appearance of a republic but in reality established a dictatorship.
Answer: speaker of the Council of Five Hundred

Question: Extract the answer to the question from the following context. Question: How did the newspapers change? Context: Shorter, black-and-white daily strips began to appear early in the 20th century, and became established in newspapers after the success in 1907 of Bud Fisher's Mutt and Jeff. Humour strips predominated at first, and in the 1920s and 1930s strips with continuing stories in genres such as adventure and drama also became popular. Thin periodicals called comic books appeared in the 1930s, at first reprinting newspaper comic strips; by the end of the decade, original content began to dominate. The success in 1938 of Action Comics and its lead hero Superman marked the beginning of the Golden Age of Comic Books, in which the superhero genre was prominent.
Answer:
Shorter, black-and-white daily strips began to appear early in the 20th century
