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.

Passage 1:Sara Jordan Powell was born on October 6, 1938 in Houston, Texas, the daughter of a minister and pastor at the Turner Memorial Church of God in Christ, and his wife, who was a homemaker. She was born the third of twelve children in her family. Powell started singing at the age of two years. She is a Texas Southern University graduate with a Bachelor's degree in English while minoring in drama and history. After graduation from Texas Southern University, she headed out to Chicago, Illinois to live with her sister, and she apprenticed under, Thomas A.

After the Sallie Martin Singers, she was a part of the Voices of Melody, headed by Dr. Charles Clency. Soon thereafter her father became ill and died, and she and her husband departed for Houston in order to handle the church's affairs. While she was back in Houston, Powell became a teacher at a school, where she was encouraged to sing during a commencement ceremony, and after that she was a highly sought after local artist. Around 1971, Rev. James Cleveland eavesdropped on one of her singing engagements in Los Angeles, California, and at his request, she met with him the next day. He asked her about recording, but Powell had never given it much thought. He encouraged her, and she quickly found success in 1972 with the songs, "Touch Somebody's Life" and "When Jesus Comes," which achieved significant radio airtime, and were on her debut album "Touch Somebody's Life" that came out in 1975 on the Savoy label. She attended Southwest Theological Seminary, and obtained her Master's degree from University of St. Thomas, after achieving musical success. Powell had the opportunity to perform "Amazing Grace" for President Jimmy Carter at the White House, while they were honoring the Black Music Association, with the likes of Chuck Berry, Billy Eckstine, Evelyn "Champagne" King, and Andraé Crouch on June 7, 1979. She was an academic advisor at Oral Roberts University after she and her husband relocated there for her husband to pursue his Juris Doctor degree.

Powell had the opportunity to minister to President Bill Clinton in Memphis, Tennessee, along with Dr. Bernard Johnson, at the requested of Bishop Lewis Henry Ford.
 Passage 2:Polo got his start in Universitario de Deportes as a youth. He made his official debut in the Torneo Descentralizado on 23 April 2011, against Alianza Atletico in the ninth round of the 2011 Descentralizado season, at the age of 16. His debut match was played at home in the Monumental and finished 1–0 in favor of Universitario de Deportes. Polo played from the start and was later substituted for Raúl Ruidíaz in the 67th minute. In his second professional match, Polo scored his first senior career goal on 6 May 2011 in a league match at home against Cienciano del Cuzco. He scored his first goal in the 8th minute of the match by controlling with his head a lobbed through ball from Pablo Vitti and finishing with a strong left-footed shot into the top-right corner of the net. In a very short time, Polo earned a spot in the starting eleven and played in the following league games. In round 15, Andy was on the scoresheet again in the 3–0 home win over Unión Comercio. Then he made his Torneo Intermedio (now known as the Copa Inca) debut on 28 May 2011 in the First Round against Sport Ancash. With Universitario starting the match with mainly players from the reserves and already behind two goals, Polo entered the match in the 46th minute but could not help his side avoid the 3–2 elimination away to the Rosas Pampa Stadium in Huaraz.
 Passage 3:Ibrahim was born in Cape Town on 9 October 1934, and was baptized Adolph Johannes Brand. He attended Trafalgar High School in Cape Town's District Six, and began piano lessons at the age of seven, making his professional debut at 15. He is of mixed-race heritage, making him a Coloured person according to the South African government. His mother played piano in a church, the musical style of which would remain an influence; in addition, he learned to play several genres of music during his youth in Cape Town, including marabi, mbaqanga, and American jazz. He became well known in jazz circles in Cape Town and Johannesburg. In 1959 and 1960, Ibrahim played with the Jazz Epistles group in Sophiatown, alongside saxophonist Kippie Moeketsi, trumpeter Hugh Masekela, trombonist Jonas Gwangwa (who were all in the orchestra of the musical King Kong that opened in Johannesburg in February 1959), bassist Johnny Gertze and drummer Makaya Ntshoko; in January 1960, the six musicians went into the Gallo studio and recorded the first full-length jazz LP by Black South African musicians, Jazz Epistle Verse One, with 500 copies being produced. Although the group avoided explicitly political activity, the apartheid government was suspicious of it and other jazz groups, and targeted them heavily during the increase in state repression following the Sharpeville massacre, and eventually, the Jazz Epistles broke up.
