Example Input: Question: What city does Herc have Marlo arrested in? Passage:Sydnor and Herc watch as Marlo meets with his lieutenants. Marlo makes a phone call about picking up a "skinny girl from New York," which Herc interprets as an arrangement to pick up a supply of cocaine. Herc follows Marlo to Penn Station and has him arrested when he meets a woman who turns out to not be carrying drugs. Marlo has engineered the incident to draw out the police. Meanwhile, Greggs learns that a prisoner has offered information on the dead state's witness. However, Rawls tells Landsman to detail Greggs and Norris to uniformed duty at the polls, stalling the witness case until after the election. At school, Prez offers to help Dukie get clean clothes.

Example Input: Question: How many albums total did the Beatles record in Hamburg? Passage:Ain't She Sweet was an American album featuring four tracks recorded in Hamburg in 1961 by The Beatles featuring Tony Sheridan (except for the title song with vocal by John Lennon) and cover versions of Beatles and British Invasion-era songs recorded by the Swallows. As Atlantic Records only had rights to four Sheridan/Beatle recordings recorded by Polydor Records, they filled the rest of the album with Beatle and British Invasion cover songs. When this material was released by Atco Records, there were mono (catalogue number 33-169) and stereo (SD 33-169) editions. Atco also added additional drum overdubs to the four Sheridan cuts on top of the original drum tracks. American drummer Bernard Purdie claims to have performed overdubs of unspecified Beatles records, which would most likely have been for Ain't She Sweet, but this has never been officially confirmed.

Example Input: Question: How long did the Eurasian empire that rose in the thirteenth century last? Passage:Vajrayana had also become the major religion of Tibet and the Western Xia by the time of the rise of the Mongol Empire in the thirteenth century. As the Tibetan and Tangut peoples came under the rule of Mongol leaders during the reign of Möngke Khan (1209–1259), they increased their missionary activity in Mongolian lands, eventually converting the leadership and much of the population as well aiding in the translation of Buddhist texts into Mongolian. So it is no surprise that after the Mongol conquest of China and their establishment of the Yuan dynasty (1271–1368), the Yuan emperors made Tibetan Buddhism the official religion of China, and Tibetan monks (or, as they were called in Chinese, "barbarian monks from the West", ) were given patronage at the court. Lamas of the Sakya school like Sakya Pandita and also of the Kagyu became imperial preceptors of the Mongol Khans. The tantric deity Mahakala was used in military campaign to protect the armies during their war against China and became the protector deity of the Yuan state. They were granted unprecedented status and privileges such as temple offerings and shrines.
