Example Input: Passage: Relations between the people of Afghanistan and India traces to the Indus Valley Civilisation. Following Alexander the Great's brief occupation, the successor state of the Seleucid Empire controlled the region known today as Afghanistan. In 305 BCE, they ceded much of it to the Indian Maurya Empire as part of an alliance treaty. The Mauryans brought Buddhism from India and controlled the area south of the Hindu Kush. Their decline began 60 years after Ashoka's rule ended, leading to the Hellenistic reconquest of the region by the Greco-Bactrians. Much of it soon broke away from the Greco-Bactrians and became part of the Indo-Greek Kingdom. The Indo-Greeks had been defeated and expelled by the Indo-Scythians in the late 2nd century BCE. Much of Afghanistan has been influenced by Buddhist, Hindu and Zoroastrian cultures until the arrival of Islam in the 7th century. But despite many Afghans converting to Islam, the Muslims and Hindus lived side by side.

Example Input: Passage: After a spell at Colchester United where he scored once against A.F.C. Bournemouth, he joined Darlington at the start of the 2005–06 season, where he scored 10 goals in 21 league appearances. He moved to Cardiff City in January 2006, where he made 11 appearances including seven as substitute. He was released at the end of the season and signed by Gillingham. He scored his first goal for Gillingham away to Blackpool on 26 August 2006 in a game which ended 1–1. He struggled to hold down a place in the team during his first season at the club and was sent on loan to Bradford City the next season. He made his debut on 10 August 2007 and scored an equaliser to secure a 1–1 draw against Macclesfield Town. He played 18 league games, scoring six league goals for Bradford but his loan was not extended when it expired at the end of 2007 partly because of financial reasons. He returned to Gillingham but was immediately placed on the transfer list, and on 29 January 2008 he moved on a free transfer for a second spell at Darlington. Injury delayed his debut back at Darlington, which came on 23 February 2008 against Bury when he scored a sixth-minute penalty in a 2–1 victory. He played eight league games for Darlington, scoring three goals, and was a substitute in both legs of the play-off semi-finals against Rochdale, but after Darlington's defeat on penalties to Rochdale, he was released by manager Dave Penney.

Example Input: Passage: After briefly continuing his tag team with Big Josh, Hammer returned to singles competition and faced Steve Austin for the World Television Championship on the January 12 episode of Main Event, but was unable to win the title. After the loss, Hammer competed sporadically throughout the rest of the spring (including a brief feud with JT Southern) before returning full-time in August 1992. Hammer would fall to Greg Valentine and Nikita Koloff before his push began to accelerate. In September he went on a ten match winning streak, defeating Dallas Page, Vinnie Vegas (Kevin Nash), and Super Invader (Hercules Hernandez). He received a US title shot against Rick Rude on the November 21st episode of WCW Power Hour but came up short. Hammer teamed with Erik Watts at Halloween Havoc and was victorious against The Vegas Connection. For the remainder of October and November he was strongly pushed, going 19-2 in a streak that included victories over Tony Atlas, The Barbarian, and Mustafa Saed. He would also team with Brad Armstrong in a brief feud with Page and Vegas.
