Let me give you an 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.

 Passage 2:India's present syncretic culture is reflected in the fused Hindu-muslim spiritual connotations, forms, symbols, aesthetics, crafts and weaves, for example Kashmiri muslim carpet makers feature Durga in their patterns, muslim sculptors making idols of Durga, and Hindu craftsmen create the Muharram tazia. This religious syncretism is a fusion of Hindu cultural elements with Muslim religious elements. It is based on the vasudhaiva kutumbakam, unity in diversity, multi-communitarianism and ganga-jamuni tehzeeb, It is born out of centuries of interfaith exchange and accommodation among Indian origin religions (Hindu, Buddhist, Jain, Sikh) and foreign origin religions (Muslim and Christian) where communities preserve own cultural and religious identities while facilitating the shared celebration of festivals, customs and traditions. In this syncretic culture, the shared Indian national identity is separated from the personal religious identity, and the nation and common social good comes first above the personal religion. Despite the partition of India, and resulting creation of Pakistan based on the concept of separate islamic nation for domination of muslims, this composite multiculturalism is integral to the present society of India. India is officially a secular nation, a concept legalised in the constitution of India. Contrastingly, constitution of Pakistan has Islam as its state religion, teaching of quran and islamiyat is compulsary,Constitution of Pakistan: Constitution of Pakistan, 1973 – Article: 31 Islamic way of life, Article 31 No. 2, 1973, Retrieved 22 August 2018. only muslims can become Prime Minister or President of Pakistan and nonmuslims are not given equal rights, Ahmadia muslims having equal constitutional rights in India are legally persecuted in Pakistan and constitutionally banned from calling themselves Muslims.
