Example input: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage 1: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lô during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,
. Passage 2: John Ford (1894–1973) was an American film director whose career spanned from 1913 to 1971. During this time he directed more than 140 films. Born in Maine, Ford entered the filmmaking industry shortly after graduating from high school with the help of his older brother, Francis Ford, who had established himself as a leading man and director for Universal Studios. After working as an actor, assistant director, stuntman, and prop man – often for his brother – Universal gave Ford the opportunity to direct in 1917. Initially working in short films, he quickly moved into features, largely with Harry Carey as his star. In 1920 Ford left Universal and began working for the Fox Film Corporation. During the next ten years he directed more than 30 films, including the westerns The Iron Horse (1924) and 3 Bad Men (1926), both starring George O'Brien, the war drama Four Sons and the Irish romantic drama Hangman's House (both 1928 and both starring Victor McLaglen). In the same year of these last two films, Ford directed his first all-talking film, the short Napoleon's Barber. The following year he directed his first all-talking feature, The Black Watch.
. Passage 3: Since the late 1970s, the central part of NYU is its Washington Square campus in the heart of Greenwich Village. Despite being public property, and expanding the Fifth Avenue axis into Washington Square Park, the Washington Square Arch is the unofficial symbol of NYU. Until 2008, NYU's commencement ceremony was held in Washington Square Park. However, due to space constraints, ceremonies are now held at the Yankee Stadium. Important facilities at Washington Square are the Elmer Holmes Bobst Library, designed by Philip Johnson and Richard Foster, who also designed several other structures, such as Tisch Hall, Meyer Hall, and the Hagop Kevorkian Center. When designing these buildings Johnson and Foster also set up a master plan for a complete redesign of the NYU Washington Square campus. However, it was never implemented. Other historic buildings include the Silver Center (formerly known as "Main building"); the Brown Building of Science; Judson Hall, which houses the King Juan Carlos I of Spain Center; Vanderbilt Hall, the historic townhouse row on Washington Square North; The Grey Art Gallery at 100 Washington Square East, housing the New York University art collection and featuring museum quality exhibitions; the Kaufman Management Center; and the Torch Club – the NYU dining and club facility for alumni, faculty, and administrators. Just a block south of Washington Square is NYU's Washington Square Village, housing graduate students and junior and senior faculty residences in the Silver Towers, designed by I. M. Pei, where an enlargement of Picasso's sculpture Bust of Sylvette (1934) is displayed.

Q: Question: How old was Liu Yong when Ge Fei was elected to the Hall of Fame? Passage 1:Bergevin was drafted by the NHL's Chicago Blackhawks in the 1983 NHL Entry Draft, third round, 59th overall. After a junior career with the Chicoutimi Saguenéens of the Quebec Major Junior Hockey League (QMJHL), he made the Black Hawks in 1984 and played with Chicago for the next five seasons before being traded to the New York Islanders. His career with the Islanders was brief, and he spent much of that time with their American Hockey League (AHL) affiliate Springfield Indians, whom he helped lead to consecutive Calder Cup championships in 1990 and 1991. In the 1991 season he was traded to the Hartford Whalers and became a fan favorite for his skilled checking. The 1991–92 was his best season statistically, scoring 7 goals and 17 assists for 24 points.
 Passage 2:Ge Fei (; born 9 October 1975) is a retired Chinese badminton player in the 1990s who is one of the most successful doubles specialists in the sport's history. Among many international titles, Ge won two Olympic gold medals and two IBF World Championship gold medals in the women's doubles with her regular partner Gu Jun and a World Championship gold medal in the mixed doubles with Liu Yong. Ge was also a member of Chinese teams that captured the Uber Cup (women's world team trophy) in 1998 and 2000. Ge and Gu Jun were the world's dominant women's doubles team from the mid-1990s to their retirement after the 2000 Olympics, winning over thirty top tier international titles together. Ge Fei was elected to the Hall of Fame in 2008.

After the announcement, Taylor-Johnson told Digital Spy that "It's not my decision [to return], and I haven't been privy to any of the discussions." On November 12, 2015, TheWrap reported that James Foley would direct both sequels, which would be shot back-to-back in 2016, with Niall Leonard writing the script and Michael De Luca and Dana Brunetti returning to produce, along with E. L. James and Marcus Viscidi. Dakota Johnson and Jamie Dornan were also set to return in the lead roles.
