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 was the age difference between the commodore and his brother? Passage:Samuel Shaw was a Revolutionary War naval officer who, along with Richard Marven, were the first whistleblowers of the infant United States. As a whistleblower, Shaw was instrumental in the Continental Congress' passage of the first whistleblower protection law in the United States. Shaw, a midshipman, and Marven, a third lieutenant in the Continental Navy, were moved to act after witnessing the torture of British prisoners of war by Commodore Esek Hopkins, then Commander-in-Chief of the Continental Navy. Shaw and Marven were both from Rhode Island, as was Hopkins, whose brother was Stephen Hopkins, Governor of the new state, and a signatory to the Declaration of Independence. For reporting the misconduct of the Navy's highest officer, Shaw and Marven were both dismissed from the Navy. Worse still, Hopkins then filed a criminal libel suit against Shaw and Marven in the Rhode Island Courts.

Example Input: Question: Which team has won more of their Super Bowl appearances, the Dallas Cowboys or the Denver Broncos? Passage:The Pittsburgh Steelers compete in the National Football League (NFL) as a member club of the American Football Conference (AFC) North division. Founded in 1933, the Steelers are the oldest franchise in the AFC; seven franchises in the National Football Conference (NFC) have longer tenures in the NFL. The team struggled to be competitive in its early history, posting winning records in just 8 of its first 39 seasons. Since the AFL–NFL merger in 1970, however, it has appeared in eight Super Bowls and one of only two teams, along with the New England Patriots have won the Super Bowl six times. The six championships place the Steelers fourth in the league in terms of total championships (including those prior to the first Super Bowl), trailing only the Green Bay Packers (13 championships), the Chicago Bears (9) and the New York Giants (8). The club's 15 AFC Championship Game appearances are second all-time, behind the Patriots (16). In addition, they have hosted the second-most conference championship games (11) than any franchise in either conference, and are tied for second with the Dallas Cowboys and Denver Broncos with eight Super Bowl appearances; the Patriots currently hold the record of eleven appearances, as of 2019.
