One 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.

Now, solve this: Question: Which of the two universities Windschuttle attended had a larger student population? Passage 1:After education at Canterbury Boys' High School (where he was a contemporary of former Liberal Australian prime minister John Howard), Windschuttle was a journalist on newspapers and magazines in Sydney. He completed a BA (first class honours in history) at the University of Sydney in 1969, and an MA (honours in politics) at Macquarie University in 1978. He enrolled in a PhD but did not submit it; instead he published it under the title The Media with Penguin Books. In 1973, he became a tutor in Australian history at the University of New South Wales (UNSW). Between 1977 and 1981, Windschuttle was lecturer in Australian history and in journalism at the New South Wales Institute of Technology (now the University of Technology, Sydney) before returning to UNSW in 1983 as lecturer/senior lecturer in social policy. He resigned from UNSW in 1993 and since then he has been publisher of Macleay Press and a regular visiting and guest lecturer on history and historiography at American universities. In June 2006, he was appointed to the Board of the Australian Broadcasting Corporation (ABC), Australia's non-commercial public broadcaster.
 Passage 2:Quinn emigrated from Canada with a falsified passport and entered the adult entertainment industry in the late 1980s, while she was underage by using a fake ID. She began stripping in Canada when she was 14. Two years later she met pornographic actress Erica Boyer and moved to Los Angeles with her. Quinn began performing in adult films at the age of 16 after Boyer introduced her to agent Jim South. Quinn misrepresented her birth year as 1968, which would have made her 22 at the time of her adult film debut. Her first scene was in the film Space Virgins, and it was a five-person group sex scene with two men and two other women, besides Quinn. She won the 1991 AVN Award for Best Group Sex Scene - Video alongside Sunny McKay & Rocco Siffredi for their performance in Buttman's Ultimate Workout. By November 1991 she had appeared in approximately 100 adult films, 60 of which were shot while she was still a minor.
 Passage 3:Charles I is supposed to have created him a baronet 4 May 1645. Of this creation, the first of a physician to that rank, no record exists, but the accurate Le Neve did not doubt the fact, and explained the absence of enrolment. He claimed to have been Physician-General to the army of Charles I. With his friend Walter Charleton, Greaves became travelling physician to Charles II, but settled in London in 1653, and was admitted a fellow of the College of Physicians 18 October 1657. He delivered the Harveian oration at the College of Physicians 25 July 1661 (London, 1667, 4to), of which the original manuscript is in the British Museum (Sloane 302). He says that before Harvey the source of the circulation was as unknown as that of the Nile, and compares England to a heart, whence the knowledge of the circulation was driven forth to other lands. He became physician in ordinary to Charles II, and owned the lands of St Leonard's Forest in Sussex, including that part which became Leonardslee. He married Alicia Nevett (1624–1684), widow of Peter Calf (d. 1668). Greaves lived in Covent Garden, died there 11 Nov. 1680, and was buried in the church of St. Paul's, Covent Garden.
