Problem: 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.

Problem: Question: Who was in charge of the NIH the year Fanon went to the US for cancer treatment? Passage 1:Upon his return to Tunis, after his exhausting trip across the Sahara to open a Third Front, Fanon was diagnosed with leukemia. He went to the Soviet Union for treatment and experienced some remission of his illness. When he came back to Tunis once again, he dictated his testament The Wretched of the Earth. When he was not confined to his bed, he delivered lectures to Armée de Libération Nationale (ALN) officers at Ghardimao on the Algero-Tunisian border. He made a final visit to Sartre in Rome. In 1961, the CIA arranged a trip to the U.S. for further leukemia treatment at a National Institutes of Health facility. During his time in the United States, Fanon was handled by CIA agent Oliver Iselin.
 Passage 2:Most versions of "Bottle Up and Go" recorded after Tommy McClennan's single use a combination of his verses and new lyrics. Early versions (often with a variation on the title) include those by Blind Boy Fuller (as "Step It Up and Go") (1940), Lead Belly (1940), and Sonny Terry and Brownie McGhee (1942). Western swing band Maddox Brothers and Rose recorded it as "New Step It Up and Go" (1951). B.B. King recorded a version as "Shake It Up and Go" (1952) "although he confuses himself by saying 'bottle up and go' half the time". He later re-recorded it for the Blues on the Bayou album (1998). The Everly Brothers included it as "Step It Up and Go" for Instant Party! (1962) and The Everly Brothers Reunion Concert (1983). Bob Dylan recorded "Step It Up and Go" for Good as I Been to You (1992). The song has also been regularly featured by Mungo Jerry in their live performances. It has been suggested that Chuck Berry's "Too Much Monkey Business" is adapted from McClennan's song.
 Passage 3:The history of Lubartów begins on May 29, 1543, when King Sigismund the Old allowed local nobleman Piotr Firlej to found a town called Lewartów (the original name comes from Lewart, the coat of arms of the Firlej family). The town became famous when it belonged to Mikołaj Firlej, the son of Piotr Firlej. In the late 16th century, it was one of centers of Calvinism in Lesser Poland, and Mikołaj Firlej invited here a number of skilled artisans from France, Germany and Holland, as well as cattle breeders. Lewartów frequently changed owners. In the early 18th century it belonged to the Sanguszko family, who rebuilt the palace, built two Baroque churches and tenement houses. Upon request of Paweł Karol Sanguszko, on November 22, 1744, King Augustus III of Poland changed the name of the town to Lubartów (in honor of Lubart - Liubartas, the son of Lithuanian Prince Gediminas; Sanguszko believed that Liubartas was the founder of his family). King Augustus granted a new coat of arms to the town. The 19th century was not lucky for Lubartów, as the town, which from 1815 to 1915 belonged to Russian-controlled Congress Poland, burned several times (1831, 1838, 1846). In 1866 it became the seat of a county, and slowly began modernization. By 1912 it had seven manufacturing enterprises, including mills and a brewery, in 1922, glassworks were opened.
