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-Lo 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 (18941973) 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 many years were there between Constantinople's establishment and Basil I's accession to the throne? Passage 1:American entertainer Madonna has worked in twenty-six feature films (twenty-one as an actress), ten short films, three theatrical plays, ten television episodes, and appeared in sixteen commercials. at age 16, she auditioned in a high-school short movie called "the egg" where she played a teenage sunbather relaxing at a patio eating raw eggs. In 1979, she made her acting debut in the low-budget feature A Certain Sacrifice. Its commercial release in 1985 coincided with the success of her second studio album, Like a Virgin. That same year, she made a cameo appearance as a club singer in the film Vision Quest; she also garnered commercial and critical success for the title role in Susan Seidelman's Desperately Seeking Susan. Madonna followed it with a leading role in the adventure drama Shanghai Surprise (1986), with her then-husband, actor Sean Penn. The film was panned by critics, and Madonna received her first Golden Raspberry Award for Worst Actress. Her next films such as Who's That Girl (1987) and Bloodhounds of Broadway (1989) were critical and commercial failures. In 1986, she made her theatrical debut in David Rabe's Goose and Tom-Tom and her first commercial for Mitsubishi in Japan. She starred in the 1989 commercial for Pepsi-Cola alongside her song "Like a Prayer". Due to the controversy surrounding the song's music video, the commercial was revoked and her contract with Pepsi-Cola was cancelled.
Passage 2:'Robert D. Raiford (December 27, 1927 November 17, 2017) was an American radio broadcaster and actor, best known for his political/social commentaries delivered during The John Boy and Billy Big Show, a morning radio program heard on stations throughout the American South. He was from Concord, North Carolina and majored in communication at the University of South Carolina. Raiford got his start in broadcasting in 1944 by calling play by play at baseball games. His first real radio job was at WEGO (AM) in Concord, North Carolina. Raiford has appeared in 28 movies, often portraying judge characters. He frequently closed his commentaries with the line "Who says that? I say that!", which also served as the title of a book containing excerpts from these segments. Early in his career, Raiford worked for WTOP radio and WTOP-TV, both CBS News affiliates in Washington, D.C.. His best-known work was a live radio broadcast on WTOP, a CBS Radio affiliate, covering the state funeral of President John F. Kennedy. He also worked at Charlotte radio station WBT. Raiford also hosted a show on WIST, which aired Charlotte's first telephone talk radio format. He later taught Communications at the University of North Carolina at Charlotte. From 1978 to 1986, Raiford was a news anchor and talk show host for Charlotte's NBC television affiliate. It was known as WRET-TV and then WPCQ-TV during his tenure there; it is now WCNC-TV. On the June 9, 2016, episode of The John Boy and Billy Big Show, John Isley ("John Boy") announced that Raiford had retired from the show, due to suffering a stroke the previous August that greatly affected his speech and mobility. Raiford had not delivered any commentaries during the intervening months, choosing to focus on his recovery instead.
Passage 3:Following the fall of the Exarchate of Ravenna in 751, Byzantium had been absent from the affairs of southern Italy for almost a century, but the accession of Basil I (reigned 867886) to the throne of Constantinople changed this: from 868 on, the imperial fleet and Byzantine diplomats were employed in an effort to secure the Adriatic Sea from Saracen raids, re-establish Byzantine dominance over Dalmatia, and extend Byzantine control once more over parts of Italy. As a result of these efforts, Otranto was taken from the Saracens in 873, and Bari, captured from Arabs by the Holy Roman Emperor Louis II in 871, passed under Byzantine control in 876. The expeditions of the capable general Nikephoros Phokas the Elder in the mid-880s further extended Byzantine control over most of Apulia and Calabria. These victories were followed up by his successors and laid the foundation of a resurgence of Byzantine power in southern Italy, culminating in the establishment of the theme of Longobardia in c. 892. The regions of Apulia, Calabria and Basilicata would remain firmly under Byzantine control until the 11th century. In c. 965, a new theme, that of Lucania, was established, and the strategos (military governor) of Bari was raised to the title of katepano of Italy, usually with the rank of patrikios. The title of katepano meant "the uppermost" in Greek. This elevation was deemed militarily necessary after the final loss of nearby Sicily, a previously Byzantine possession, to the Arabs.
