[Q]: 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.

[Q]: Question: Which rolling stock did the Turboliner replace? Passage:Following its takeover of most passenger rail service in the United States on May 1, 1971, Amtrak retained the Abraham Lincoln as a daily Chicago-St. Louis service, operating in tandem with the GM&O's old Limited. In November of that year Amtrak extended both the Abraham Lincoln and the Limited (now known as the Prairie State) through Chicago to Milwaukee, Wisconsin. In October 1973, Amtrak replaced the rolling stock with the new French-built Turboliner; as part of this change the trains were re-branded as Turboliners and truncated to Chicago. In February 1976 Amtrak returned conventional rolling stock to the route and revived the Abraham Lincoln name along with the Ann Rutledge. Amtrak added the State House to the Chicago-St. Louis corridor in 1977. Also in 1977, Amtrak extended the Abraham Lincoln to Kansas City and renamed it the Ann Rutledge–a name that had briefly disappeared from the timetable in 1976-77 when Amtrak extended the Inter-American to Chicago. Today service between Chicago and St. Louis is handled by the "Lincoln Service".
