Example Input: Question: Whom founded sixdegrees.com? Passage:This newer generation of social networking sites began to flourish with the emergence of SixDegrees.com in 1997, followed by Open Diary in 1998, Mixi in 1999, Makeoutclub in 2000, Hub Culture and Friendster in 2002 or Canada's first online social network Nexopia in 2003, and soon became part of the Internet mainstream. However, thanks to the nation's high Internet penetration rate, the first mass social networking site was the South Korean service, Cyworld, launched as a blog-based site in 1999 and social networking features added in 2001. It also became one of the first companies to profit from the sale of virtual goods. Friendster was followed by MySpace and LinkedIn a year later, and eventually Bebo. Friendster became very popular in the Pacific Islands. Orkut became the first popular social networking service in Brazil (although most of its very first users were from the United States) and quickly grew in popularity in India (Madhavan, 2007). Attesting to the rapid increase in social networking sites' popularity, by 2005, it was reported that Myspace was getting more page views than Google. Facebook, launched in 2004, became the largest social networking site in the world in early 2009. Facebook was first introduced as a Harvard social networking site, expanding to other universities and eventually, anyone. The term social media was introduced and soon became widespread.

Example Input: Question: What other teammates had Roberts had before partnering with Lawson? Passage:Lawson accepted an offer from Yamaha to contest the 500cc World Championship as Kenny Roberts' teammate for the 1983 season. Lawson spent the 1983 season learning the ropes of the Grand Prix circuit. In 1984, Lawson began winning regularly and won the 1984 World Championship. It would mark the first of four world titles Lawson would go on to win. In 1985, he won the prestigious Imola 200 pre-season race. After winning two more titles for Yamaha in 1986 and 1988, Lawson shocked the racing world by announcing he would be leaving Yamaha to sign with their arch-rivals Rothmans Honda as teammate to his own archrival, Australia's 1987 World Champion Wayne Gardner. By switching teams, Lawson also fulfilled his desire to work with Erv Kanemoto. After Gardner crashed and broke his leg during the third round at Laguna Seca, Lawson went on to win the 1989 title for Honda, becoming the first rider to win back-to-back championships on machines from different manufacturers. By winning with both Yamaha and Honda, Lawson silenced his critics who believed he would not be as successful away from the factory Marlboro Yamaha team.

Example Input: Question: How many years after it was founded did Harrison graduate from Ontario Agricultural College? Passage:Originally from New Brunswick, Harrison graduated from Nova Scotia Agricultural College in 1922, and, in 1924, from the Ontario Agricultural College with a B.Sc. in agriculture. He earned an MSc in plant pathology from Macdonald Campus of McGill University a year later. A doctoral degree he started at the University of Toronto in 1929 was abandoned due to the Great Depression. He established a herbarium of mycological specimens where he was employed for many years at the Kentville Research Station (now the Atlantic Food and Horticulture Research Centre); most of his collections are now housed at the Canadian National Mycological Herbarium. His early research concerned the fungal infestation of plants, such as that of Colletotrichum lindemuthianum on beans (Phaseolus). Working with John Frederick DeWitt Hockey, they made many contributions to the control and prevention of diseases of horticultural crops. They were among the first to use the sticky slide spore trap to estimate the densities of fungal spores.
