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.

Question: How large was the University of Helsinki's endowment the year Kaila graduated from that school? Passage 1:Prince Lvov was born in Dresden, Germany, and descended from the sovereign Rurik dynasty princes of Yaroslavl. His family moved home to Popovka in the Aleksin district of Tula Governorate from Germany soon after his birth. He graduated from the University of Moscow with a degree in law, then worked in the civil service until 1893. During the Russo-Japanese War he organized relief work in the East and in 1905 joined the liberal Constitutional Democratic Party. A year later he won election to the First Duma, and was nominated for a ministerial position. He became chairman of the All-Russian Union of Zemstvos in 1914, and in 1915 he became a leader of the Union of Zemstvos as well as a member of Zemgor, a joint committee of the Union of Zemstvos and the Union of Towns that helped supply the military and tend to the wounded from World War I. In December 1916, after Prince Lvov's tirades at the Congress of Zemstvos, the Voluntary Organisations would allow no one to work for the government unless their collaboration were purchased by political concessions.
 Passage 2:Eino Kaila was born in Alajärvi, Finland. Kaila's father, Erkki Kaila was a Protestant minister and later archbishop. He graduated from the University of Helsinki in 1910. In the 1920s he worked in the field of literary criticism and psychology as a professor at the University of Turku and is said to have been the first to introduce gestalt psychology to Finland. He was a part of the cultural circles of the time with the likes of Jean Sibelius and Frans Eemil Sillanpää. In 1916 he married the painter Anna Lovisa Snellman, who was granddaughter of Johan Vilhelm Snellman. He had University positions as lecturer in Helsinki and professor in Turku, and in 1930 he was appointed professor of theoretical philosophy at the University of Helsinki. In the 1930s, Kaila was closely associated with the Vienna Circle.
 Passage 3:Wheaton remained in command of the brigade during Lt. Gen. Ulysses S. Grant's Overland Campaign in 1864, as well as during the subsequent Siege of Petersburg. His men were hurried by train to Washington, D.C., in time to help repel Jubal Early's raid on the capital. During the ensuing operations in the Shenandoah Valley, under Maj. Gen. Philip Sheridan, Wheaton was promoted to command of the first division after Brig. Gen. David Allen Russell was killed at the Third Battle of Winchester. His division fought well in subsequent battles. In the Battle of Sailors Creek Virginia, on April 6, 1865, his division captured Confederate Major General George Washington Custis Lee, son of Robert E. Lee. After the return of VI Corps to the Petersburg front, Wheaton earned the brevet rank of major general in the volunteer army and was brevetted colonel in the regular services.
