Part 2. Example
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 deep is the body of water where Audrey's formation was first noticed? Passage 1:Pocock joined the Royal Air Force in 1974. He served as Officer Commanding Support Wing at the joint RAF and Army base at Akrotiri before becoming briefing officer to the Chief of the Air Staff. He went on to be Group Captain in charge of the RAF estate in 1996, Air Commodore Plans at RAF Logistics Command in 1997 and Air Commodore Plans and Policy at RAF Personnel and Training Command in 1999.

 Passage 2:Allison co-founded D Magazine -- a monthly magazine covering Dallas -- in 1974, with backing from Dallas investor Ray Lee Hunt. In 1981, he and a group of investors purchased Sport Magazine, which they sold in 1984. He went on to found and publish Art & Antiques in 1984. In 1985, Allison was asked by William F. Buckley, Jr. to join the board of directors of the National Review, and in 1980 he became its publisher, succeeding William A. Rusher. In 1981 or 1982 Allison sold his company Allison Publications, publisher of Art & Antiques. In 1993, he resigned as publisher of National Review. In 1995, he and investor Harlan Crow repurchased D Magazine, and in 2001, Allison bought out Crow to become the magazine company's sole owner. In 1993, Allison edited a new edition of The Bible To Be Read As Living Literature, published by Simon & Schuster. He is also the author of Is That In The Bible?

 Passage 3:The formation and development of Hurricane Audrey was multi-faceted. One contributor to Audrey's formation—an area of anomalously low pressures roughly above sea level—was traced back to its first detection in the western Caribbean Sea on June 11. In an analysis of weather patterns from June 1957, Weather Bureau meteorologist William H. Klein noted the potential for research on similar disturbances to shed light on tropical cyclone development. Concurrently, surface observations suggested the progression of a disorganized tropical wave tracking westward across the Caribbean Sea beginning on June 20, eventually entering the Bay of Campeche on June 22. At 12:00 UTC on June 24 (7:00 a.m. CST), the resulting disturbance organized into a tropical depression based on ship reports in the bay; at the time, the first indication of a developing tropical cyclone originated from a report from a shrimp boat. The depression was in a highly favorable environment for intensification in the western Gulf of Mexico; sea surface temperatures in the area were at , or 3 °F (2 °C) above normal for the time of year. In addition, the latitudinal alignment of a polar trough over the Great Plains and the nascent disturbance in the Bay of Campeche created an environment suitable for outflow in the upper-levels of the atmosphere. Taking advantage of these conditions, Audrey reached tropical storm strength just six hours after being classified as a tropical depression while remaining nearly stationary.
