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.

. 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.

New input: Question: At what age did Craig Fairbrass return to EastEnders as an antagonist? Passage 1:Fred Trump was one of the biggest real estate developers in New York. Using their inheritance, Fred and his mother Elizabeth founded E. Trump & Son. Fred married Mary MacLeod (19122000), 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 (nee Smith). At age 17, she immigrated to the United States and started working as a maid in New York.

Fred was the father of the businessman Donald Trump, who became president of the real estate company in 1971, and renamed it the Trump Organization. Donald Trump has said that he is "proud" of his German heritage, having served as grand marshal of the 1999 German-American Steuben Parade in New York City.

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).
