Example Input: Question: What state was the president who appointed Nelson to the President's Export Council from? Passage:In 1967 at the start of the governorship of Ronald Reagan one of Reagan's first actions was to fire Nelson from her state government post at the Consumer Counsel. Nelson said that this was because she was disliked by Reagan's supporters, including the California Grocer's Association and the California Manufacturers' Association. After this she became elected president of the Consumer Federation of California. She served also on the board of Consumers Union, and would be re-elected for a total of five three-year terms on that board. From 1969-1979 served as a professor of economics at the University of Wisconsin. During this time she also served as a public governor for the American Stock Exchange. In 1968 after 15 years of work her lobbying had contributed to the passing of the Truth in Lending Act. She served two terms as president of the Consumer Federation of America from 1972-1982. She was the consumer consultant to the Office of Technology Assessment and the National Academy of Science. She petitioned the National Academy of Science to recognize the research showing saccharin as a cancer-causing agent and fluorocarbons as causing ozone depletion. In 1978 President Jimmy Carter appointed Nelson to the President's Export Council. Also in 1978 the American Council on Consumer Interests recognized her as a "Distinguished Fellow". In 1979 after the 1977 death of her husband Nelson returned to Mill Valley, California. There she was appointed to the Consumer Advisory Council of the Federal Reserve Board of Governors, the consumer advisory panel for Pacific Bell, and the San Francisco chapter of Consumer Action. At this time she said that her worst fear for the future was "That consumers will become like the feudal people of old times. That they will be so tied to a VISA card that they are not whole people. That they will be easily manipulated by the television and sellers, that they will do what is suggested to them instead of what comes from their own spirit."

Example Input: Question: What year did construction begin on the dam that the river passes through before Afterbay Dam? Passage:The Bighorn River begins as the Wind River in the Rocky Mountains at Wind River Lake, near Two Ocean Mountain and the summit of Togwotee Pass. The Wind River flows southeast receiving the east fork of the Wind River from the north, and enters the Wind River Basin, flowing past Dubois and Johnstown, to Riverton, where it receives the Little Wind River. The river then changes direction to the northeast and then the north, flowing into Boysen Reservoir, which is formed by Boysen Dam. Below the dam it enters the Wind River Canyon, where the river narrows and forms many rapids. At the end of the canyon the Wind River widens out in an area called the Wedding of the Waters where it becomes the Bighorn River and enters the Bighorn Basin. The Bighorn continues northward, passing through Thermopolis, Worland, and Basin. At Greybull it receives the Greybull River, and about north of that confluence it enters Bighorn Lake, where it is joined by the Shoshone River. North of the confluence with the Shoshone, the reservoir narrows as the river enters the Bighorn Canyon, where it crosses into Montana. At the end of the canyon, the river passes through Yellowtail Dam and Afterbay Dam. The river turns to the northeast and enters the Great Plains. At Hardin the river is joined by the Little Bighorn River. Approximately downriver from the Little Bighorn, in Big Horn County, the Bighorn empties into the Yellowstone.

Example Input: Question: In 1970 which university had more students, Princeton University or American University in Cairo? Passage:Beinin was raised as a Zionist in an American Jewish family. On graduating from high school, he spent six months working on a kibbutz, where he met his future wife. He studied Arabic at university, and received his B.A. from Princeton University in 1970. He spent the summer of 1969 studying Arabic at the American University in Cairo. Intending to move to Israel permanently, he joined other members of Hashomer Hatzair in living and working at Kibbutz Lahav. There, on encountering attitudes that struck him as being contemptuous of Palestinians, he gradually became disenchanted with his early ideals. He returned to the United States in 1973, and took his M.A. from Harvard University in 1974, and, after working in auto plants in Detroit, obtained his A.M.L.S. and Ph.D. from the University of Michigan in 1978 and 1982, respectively. He has also studied at the Hebrew University of Jerusalem.
