Example Input: Question: Who are some authors most associated with the type of books Lange enjoyed? Passage:Lange was born in Warsaw into the patriotic Jewish family of Henryk Lange (1815–1884) and Zofia née Eisenbaum (1832–1897). His father took part in the November Uprising against the Russian Partition of Poland. He was an admirerer of Romantic literature and its ideals. Antoni Lange enrolled at Warsaw University but around 1880 he was expelled for his patriotic activity by the Tsarist namiestnik Apuchtin who ruled the university at that time. He supported himself financially as a tutor but also published poetry under the pen-names Napierski and Antoni Wrzesień. He decided to study in Paris where he encountered new trends in literature, philosophy and art. In France he became familiar with the theories of Jean Martin Charcot, as well as Spiritualism, parapsychology, the philosophy of Arthur Schopenhauer and Friedrich Nietzsche, oriental religions, European and Eastern literature and modern literary criticism. He took part in the literary meetings of Stéphane Mallarmé.

Example Input: Question: How many total albums have the Swedish pop group ABBA released? Passage:The Definitive Collection is a 2001 compilation album of all the singles released by Swedish pop group ABBA. It consisted of two discs: the first featuring the singles from 1972–79 ("People Need Love" to "Does Your Mother Know"), and the second including the singles from 1979–82 ("Voulez-Vous" to "Under Attack"), with the tracks being listed in chronological order. The main exception is the track "Thank You for the Music", which, despite being written and recorded in 1977, was in fact released as a single (primarily in the UK) in 1983 after the band had split up. It appears on disc two, along with two bonus tracks, "Ring Ring" (1974 UK single remix), and "Voulez-Vous" (1979 US promo extended remix). The Australian version of The Definitive Collection adds a further two bonus tracks: "Rock Me" and "Hasta Mañana". The 1974 remix of "Ring Ring" is the first appearance on CD of this version mastered from the original master tape, after the UK single master tapes had been returned to Polar Music by the former UK licensees, Epic Records. The track's previous appearance on CD, in a 1999 singles boxed set, was mastered from a vinyl single.

Example Input: Question: What was the name of the convicted rapist/murderer's mother that Don Dunstan advocated for? Passage:In the late 1950s, Dunstan became well known for his campaign against the death penalty being imposed on Max Stuart, who was convicted of rape and murder of a small girl. He harried Premier Thomas Playford IV aggressively over the matter, creating an uproar over what he saw as an unfair process. Playford eventually relented, and appeared shaken thereafter; the event was seen as a turning point in the Liberal and Country League's decline, and Labor gained momentum. During Labor's time in opposition, Dunstan was prominent in securing some reforms in Aboriginal rights, and was at the forefront of Labor abandoning the White Australia Policy. Labor conducted an extensive campaign in marginal LCL seats at the 1965 election, resulting in 21 of 39 seats, with Frank Walsh and the Labor Party taking power and Dunstan becoming Attorney-General. The LCL opposition changed leaders and installed the young Steele Hall, worrying Labor as the elderly Walsh appeared bumbling in contrast. This resulted in Labor replacing Walsh with Dunstan. Despite maintaining a much larger vote over the LCL, Labor lost two seats at the 1968 election, with the LCL forming government with support of an independent. Dunstan responded by increasing his attacks on the Playmander and was able to convincingly sustain Playmander attacks with the effect of convincing the LCL into watering down the malapportionment. Again with little change in Labor's vote but with the Playmander removed, Labor won 27 of 47 seats at the 1970 election. With a fairer seat and boundary system in place, Dunstan won three more elections, in 1973, 1975 and 1977.
