Example Input: Question: How old as Patsy Palmer the year that Craig Fairbrass first appeared on EastEnders? Passage 1:Dan Sullivan is a fictional character from the BBC soap opera EastEnders, played by Craig Fairbrass. Dan appeared on the show as a regular from 7 June 1999 to 10 July 2000 before returning as one of the show's primary antagonists from 26 February to 16 August 2001. He became central to a storyline involving a love triangle between himself, his lover Carol Jackson (Lindsey Coulson), and her daughter Bianca (Patsy Palmer) — whom Dan embarks on an affair with. Soon afterwards, the character developed an intense feud with local hardman Phil Mitchell (Steve McFadden); the pair started out as best-friends, but ended up becoming archenemies after Phil conned Dan's ownership of The Queen Victoria public house. During the course of their escalating rivalry, Dan become a prime suspect in Phil's shooting after the latter gets shot on the night their ex-lover Mel Healy (Tamzin Outhwaite) married Dan and Phil's fellow nemesis Steve Owen (Martin Kemp). Although Mel's best-friend and Phil's ex-girlfriend Lisa Shaw (Lucy Benjamin) was revealed to be the shooter, Phil ended up framing Dan for the crime - which leads to Dan being wrongfully imprisoned prior to his trial in mid-summer 2001; the trial culminated with Dan being found not guilty, and the character then departed the show after kidnapping Mel and holding her ransom to get revenge on Phil and Steve for conspiring to get him sent down.

Fred married Mary MacLeod (1912–2000), a native of Tong, a small village near Stornoway, in the Western Isles of Scotland. She was the daughter of fisherman Malcolm MacLeod and Mary MacLeod (née Smith). At age 17, she immigrated to the United States and started working as a maid in New York.

Example Input: Question: As the Pike enters Bellmawr, which of the two routes whose exits it interchanges with is longest? Passage 1:The National Weather Service Boise, Idaho is a weather forecast office responsible for weather forecasts, warnings and local statements as well as aviation weather forecasts and fire weather forecasts for 3 counties in Southeast Oregon and 14 counties in Southwest and South central Idaho. The U.S. Weather Bureau established an office in the Sonna Building on December 1, 1898. Since then, the U.S Weather Bureau office, now known as the National Weather Service forecast office gained forecast responsibility of Southern Idaho on June 22, 1970 which was expanded to the entire state of Idaho in 1973. After modernization in 1993, the forecast responsibility was changed to Southeast Oregon and Southwest Idaho. The current office in Boise maintains a WSR-88D (NEXRAD) radar system, 8 Automated airport weather station (ASOS) systems and Advanced Weather Interactive Processing System (AWIPS) that greatly improve forecasting in the region. Continuous weather observations have been maintained for the city of Boise since February 1, 1864 about 5 months after the U.S. Army established Fort Boise. The post surgeon for the U.S. Army took observations until July 1, 1877 when the U.S. Signal Service, established an office downtown. The Signal Office was discontinued on July 1, 1890.
 Passage 2:The Black Horse Pike heads south from US 130 in Camden as a four-lane, divided highway comprising Route 168, which continues north of US 130 on Mt. Ephraim Avenue. It heads south and interchanges Route 76C, which heads west and provides access to Interstate 76 (I-76) and the Walt Whitman Bridge. It passes through Haddon Township with many jughandles at intersections. It then passes through Mt. Ephraim, where the road was restriped in the late 1990s reducing it from four lanes to two, and enters Bellmawr, where it interchanges with exit 28 of I-295 and exit 3 of the New Jersey Turnpike (NJTP). It then enters Runnemede, where it crosses Route 41 and County Route 544 (CR 544). It then heads into Gloucester Township and interchanges with Route 42. It continues south, passing through Blackwood, where it intersects CR 534, and then widens back into a four-lane, divided highway. It then heads toward the southern terminus of the North–South Freeway (Route 42) and the western terminus of the Atlantic City Expressway, where Route 168 ends and the Black Horse Pike becomes Route 42.
 Passage 3:In 1625, at Lake Kurukove in Kremenchuk, the Treaty of Kurukove was signed between the Cossacks and the Poles. Since the establishment of Cossack Hetmanate, the city was part of the Chyhyryn Polk (regiment). Following the Russo-Polish War (1654–1667) and Treaty of Andrusovo, the city was secured by Tsardom of Russia and became part of the Myrhorod Polk (regiment) within the left-bank Cossack Hetmanate. The city played a key role of the Russian colonization policy of Ukraine and their strive for the shores of Black Seas as regional administrative center of the early Novorossiya Governorate and Yekaterinoslav Vice-regency (Namestnichestvo). With creation of Novorossiya Governorate, in Kremenchuk was created Dnieper Pikers Regiment and coincidentally few years later (1768–69) in the neighboring regions of Poland started out so called Koliyivshchyna (literally the Piker's unrest). Here in 1786 started his military career the Russian general Alexander Suvorov when he was appointed a commander the local garrison (in preparation of the 1787–1792 Russo-Turkish War).

Example Input: Question: Which political officer now serves as the 2nd in line to become president? Passage 1:Multiple artists have cited the band as an influence. Kele Okereke, lead singer of London band Bloc Party, said that he started making music because of Suede's Dog Man Star, and called it "the first record [he] fell in love with". Kate Jackson, lead singer of English indie rock band The Long Blondes has said in interviews of her love for Suede. In 2007, she admitted that Suede got her into music, saying: "Suede's debut album was unlike anything I'd heard before. It was the opposite of grunge, which I hated, and my escape from Bury St Edmunds." Christopher Owens of the Californian indie pop group Girls named Suede as one of his major influences, and his vocal style has been compared to that of Anderson. My Chemical Romance frontman Gerard Way cited Suede as a prominent inspiration for his 2014 solo album, Hesitant Alien. The band have also served as an influence on acts such as Sons and Daughters, Dum Dum Girls, and Drowners, who took their name from the similarly titled Suede song. Canadian rock band Destroyer named their 2017 album ken after the original title for "The Wild Ones".
 Passage 2:McKellar twice served as President pro tempore of the United States Senate, commencing in 1945, the first to hold the position under the system that has prevailed since of reserving it for the most senior member of the majority party. When Harry Truman became president in April 1945, upon FDR's death, the vice presidency became vacant (the mechanism for filling intra-term vacancies had not yet been created by the 25th Amendment), and so McKellar became the permanent presiding officer of the United States Senate. Also, as the President pro tempore of the Senate had, prior to 1886, been second in the presidential line of succession, behind only the vice president, Truman viewed McKellar as the logical wartime replacement for himself, and asked McKellar to attend all Cabinet meetings. In 1947 Truman successfully lobbied Congress to pass a new Presidential Succession Act restoring both the Speaker of the House and the President pro tempore of the Senate to the succession ahead of the Cabinet secretaries. By the time the law came into effect, McKellar was no longer in the position of President pro tempore, because Republicans held the majority in the 80th Congress. Truman vetoed the Taft-Hartley Act in 1947 to restrict labor unions, which McKellar voted in favor of. As such Truman selected Alben Barkley of Kentucky as his running mate in the 1948 presidential election. When Democrats regained control as a result of the 1948 elections, McKellar again became President pro tempore. He was therefore second in line for the presidency (behind the Speaker of the House) from January 3, 1949 until January 20, 1949, when Alben Barkley took office as Vice President of the United States.
