Example input: 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.

. 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.

Q: Question: Which of the squadrons Nichols served in is the oldest? Passage 1:Born in Bucharest, he was the fourth child (out of seventeen, of whom nine survived) born to Captain Nicolae Săulescu (known as the Romanian Army's official painter) and his wife Ecaterina (née Gaist). From 1898 to 1903, he studied at Saint Sava and Matei Basarab high schools in his native city. Săulescu then entered the Conservatory of Dramatic Art, quitting in 1904 after his first year. Leaving Bucharest, he worked as a teacher in Gorj County and a substitute in Posada, Prahova County in 1908. In 1911, he was an editor at Luceafărul magazine in Sibiu, then a part of Austria-Hungary. After returning to the Romanian capital, he was editor at Rampa (1911-1912), librarian at the Socec folk library (1912-1913), clerk at the Public Instruction Ministry, junior clerk at Casa Școalelor cultural foundation and editor at Rampa nouă ilustrată (1914). In 1908, he was a founding member of the Romanian Writers' Union.
 Passage 2:The music for the film is scored by A R Rahman replacing Imtiaz Ali's previous associate, Pritam. Mohit Chauhan has lent his voice for nine songs and he is voice of character Jordan (played by Ranbir Kapoor). In 2010, during the development of the album, Rahman stated, "Rockstar is a character driven film and as one can guess from the title, there will be lots of guitar". In 2010, several meetings of Ali and the lyricist brought into a phrase titled, "Words destroy what I have to say". The song (Jo Bhi Main) that brings out the dilemma of the protagonist. Kamil suggested the last two lines (In lafzon ke maayne jaaney kaun badalta hai, main kehta hoon kuch, aur matlab aur koi ho jaata hai) for the particular song. But Ali didn't accept the lines because the protagonist wasn't supposed to have this level of sophistication as he was not poetic. To make it sound like something that could come from character Jordan, Kamil toned down the original after a few more rounds of discussion the lines were "Jo Bhi Main Kehna Chaahoon Barbaad Kare Alfaaz Mere" in the soundtrack. Upon development of the vociferating words Sadda Haq, Kamil stated that the situation needed a politically charged number that Jordan performs before a surging crowd at the height of his artistic angst. The slogan was used by students during Kamil's college days in Punjab to protest against the administration's arbitrary announcement of exams. On writing lyrics of "Phir Se Udd Chala", the analogies, he stated on introduction of offtrack lines like "Banu Raavan, Jiyoon Mar Marke" ("I become Raavan by continuing to live each time I die"), "The line was a metaphor for character Jordan who like the demon Ravan from the mythology Ramayana, dies a number of times and yet goes on with his life and that is why I used the Ravan simile." As per Rahman two songs Jo Bhi Mein and Sadda Haq aspire to be in the tradition of song Satisfaction by The Rolling Stones and song Another Brick in the Wall by Pink Floyd. Further, he added, "Just like most rock songs stood for people's voices, here also the central character's cry relates to every one of us." In an interview with Mid-Day, he stated, "I consciously kept away from using distorted guitars and heavy snazzy music. But I have done it here in Rockstar. Plus most songs are acoustic." For the song Katiya Karun singer Harshdeep Kaur noted that the song was recorded at AR Studios, Powai, Mumbai. Rahman asked the translation of Katiya Karun lyrics to which she explained the meaning to him. The lyrics translate as, "I spin your cotton all night, the entire day is spent in this thought, I shall live and die for you, Be a spinning wheel O’ my body." Rahman wanted it to be a very catchy number as it was going to be a fun song with Jordan and Heer (played by Nargis Fakhri) on the road. Rahman started composing and created the song right in front of the singer. Kaur stated that it wasn't a folk song, only the rhyme Katiya Karun belongs to a Punjabi folk content. A part of the song was shot at a discotheque and hence, Kamil put in subtle metaphor lyrics in the song lines translating, "I will spin your cotton all night long" that indirectly implied "I will be at your services all night", thus giving it an item song touch.
