Question: Extract the answer to the question from the following context. Question: What can you use to get other sources of bitumen besides that which is on the surface? 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: situ

Question: Extract the answer to the question from the following context. Question: What portion of science was being reconciled with religion? Context: Father Joseph Carrier, C.S.C. was Director of the Science Museum and the Library and Professor of Chemistry and Physics until 1874. Carrier taught that scientific research and its promise for progress were not antagonistic to the ideals of intellectual and moral culture endorsed by the Church. One of Carrier's students was Father John Augustine Zahm (1851–1921) who was made Professor and Co-Director of the Science Department at age 23 and by 1900 was a nationally prominent scientist and naturalist. Zahm was active in the Catholic Summer School movement, which introduced Catholic laity to contemporary intellectual issues. His book Evolution and Dogma (1896) defended certain aspects of evolutionary theory as true, and argued, moreover, that even the great Church teachers Thomas Aquinas and Augustine taught something like it. The intervention of Irish American Catholics in Rome prevented Zahm's censure by the Vatican. In 1913, Zahm and former President Theodore Roosevelt embarked on a major expedition through the Amazon.
Answer: evolutionary theory

Question: Extract the answer to the question from the following context. Question: What demographic groups did the researchers study? Context: A study of haplotypes of the Y-chromosome, published in 2000, addressed the paternal origins of Ashkenazi Jews. Hammer et al. found that the Y-chromosome of Ashkenazi and Sephardic Jews contained mutations that are also common among Middle Eastern peoples, but uncommon in the general European population. This suggested that the male ancestors of the Ashkenazi Jews could be traced mostly to the Middle East. The proportion of male genetic admixture in Ashkenazi Jews amounts to less than 0.5% per generation over an estimated 80 generations, with "relatively minor contribution of European Y chromosomes to the Ashkenazim," and a total admixture estimate "very similar to Motulsky's average estimate of 12.5%." This supported the finding that "Diaspora Jews from Europe, Northwest Africa, and the Near East resemble each other more closely than they resemble their non-Jewish neighbors." "Past research found that 50–80 percent of DNA from the Ashkenazi Y chromosome, which is used to trace the male lineage, originated in the Near East," Richards said.
Answer:
Ashkenazi and Sephardic Jews
