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.

Now, solve this instance: Question: What was the round object stolen from the vault made of? Passage 1:Bingham began his professional racing career when he made four Indy Lights starts in 1997 with a best finish of 11th at Nazareth Speedway. He also participated in the 24 Hours of Daytona in a GT3-class Porsche. He returned to Daytona and made his 12 Hours of Sebring debut in 1998. In 1999 and 2000 Bingham was the #2 driver for the Hybrid R&D Riley & Scott-Ford Le Mans Prototype team in the American Le Mans Series. He also passed his Indy Racing League rookie test with Mid-America Motorsports but decided not to pursue an entry into the IRL.

 Passage 2:Due to a double election of François Louis, Prince of Conti and the Frederick Augustus I, Elector of Saxony (elected King of Poland as Augustus II) in 1697, the two claimants to the Polish throne had serious troubles with obtaining approval of the nobility for their coronation. The most difficult situation was of Elector of Saxony, who had no support of the primate Michał Stefan Radziejowski and most of the senators holding the custody of the Wawel Castle Crown Treasury. Therefore, expecting obstacles in obtaining the royal insignia, he ordered to prepare replacements before his arrival to Kraków. On the eve of the ceremony, some of the gathered decided to find a way to obtain the original regalia. Two monks Aleksander Wyhowski, prior of Czerwińsk and Mikołaj Wyżycki, prior of the Holy Cross made a hole in the castle's wall and got to the vault from which they stole the crown, scepter, sword and orb. The Dresden regalia become unnecessary, Augustus II the Strong, however, treated them as a private insignia.
 Passage 3:Wright, with French Captains Archembeau and Toccart, sailed to Corn Island and then to Bluefield's River where he left the French privateers. Arriving in Bocas del Toro several weeks later Wright joined with Dutch Captain Yankey Willems, who himself had no commission, and departed with Yanky from Boca del Toro in September sailing south along Colombia where Yanky captured a Spanish merchant ship carrying sugar and tobacco. Wright receiving Yanky's barque, as Yanky kept the merchant ship, burned his own ship and sold the Spanish tartane he had taken near Cartago to one of the Jamaican traders on board. At Curaçao they attempted to sell the Spanish cargo but were forced to leave by the Dutch Governor. They continued to sail to the Isla Aves and Islas Roques where they remained until February 1682. Returning to Islas Roques later in 1682, Wright parted from Williems, where he and his crew divided their loot and dispersed. Wright may have returned to his home in French Hispaniola. William Dampier, who had been sailing as a member of Wrights's and Willems' crew, left with John Cook and others to return to Virginia before returning to buccaneering.
