Example Input: Question: Which Pearman album saw the greatest amount of monetary success? Passage:In music, Pearman released her debut studio album at the age of seven, Here's to New Dreams (1993), which saw the moderate commercial success of the single "That's What Little Girls Are Made Of". Her subsequent studio albums, Undeniable (1999), This Is My Time (2004), and Raven-Symoné (2008) saw some commercial success on the Billboard 200 chart in the United States. She also contributed vocals to several soundtracks from her Disney projects, including The Cheetah Girls (2003), That's So Raven (2004), That's So Raven Too! (2006), and The Cheetah Girls 2 (2006), several of which were certified platinum and gold. Pearman has also lent her voice to the animated series Kim Possible for the character Monique, and films such as Tinker Bell (2008). In 2011, she starred in the lead role on the short-lived ABC Family sitcom State of Georgia. After appearing in recurring roles on Empire and Black-ish, she joined the panel of the ABC daytime talk show The View from 2015 to 2016. Since 2017, Pearman has reprised her role as Raven Baxter on Raven's Home, for which she was nominated for the Daytime Emmy Award for Outstanding Performer in Children's Programming. VH1 ranked her at number nine on their "100 Greatest Kid Stars Of All Time" list in 2012.

Example Input: 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".

Example Input: Question: What year was Deep Purple founded? Passage:Tony met Deep Purple in the early 1970s, when the last recording of Ashton, Gardner and Dyke was a collaboration with keyboardist Jon Lord on the soundtrack for a b-movie called The Last Rebel. In the meantime, Ashton had appeared on Jon Lord's first solo album Gemini Suite in 1971. In 1973, Ashton joined the group Family for their last album and tour. That same year, he and David Coverdale and Glenn Hughes were guest vocalists on Jon Lord's second album Windows. Tony became close friends with Jon Lord. In the summer of 1974, during a break in Purple's busy touring schedule, Tony Ashton and Jon Lord recorded their album First of the Big Bands. This project was launched with a gig at the London Palladium the same year and the BBC taped a special live appearance at Golders Green Hippodrome in London. The album of this show is a tour-de-force groovy, rhythm and blues, boogie piano and Hammond organ, big band fest. Tony also contributed to Roger Glover's Butterfly Ball project. In these years, Ashton and Lord found a second home in Zermatt, an alpine resort in Switzerland, sometimes to ski, but more often to offer giant and brilliant non-profit gigs in a unique complex (one hotel-two night-clubs-two restaurants and four pubs) called "Hotel Post" which was run by American-born Karl Ivarsson. Ashton managed to come to the place almost until his death, and Jon has been a regular visitor until his death even if the "(in)famous" hotel did not exist anymore.
