Teacher: In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
Teacher: Now, understand the problem? If you are still confused, see the following 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.

Reason: The question refers to the 704th unit and task about war which is decribed by Passage 1.

Now, solve this instance: Question: Which of the two Texas stations that continued to broadcast Lauck and Goff began airing programs the earliest? Passage 1:Brandon was born in Bradenton, Florida, attended elementary school in Elfers, and attended Bayonet Middle School and River Ridge High School in New Port Richey. He later attended the University of Florida, where he received a degree in English, and Brandon also received a Master's degree in fiction writing from Washington University in St. Louis. After writing Arkansas Brandon gained the attention of Barry Hannah, who nominated him for the John and Renee Grisham Writer-in-Residence program at the University of Mississippi. He then went on to work a series of warehouse and factory jobs before holding a one-year fellowship at the Gilman School and teaching at Hamline University in Minnesota. He was also the GQ's SEC College Football analyst. Self-proclaimed worshiper of Joy Williams.
 Passage 2:Swayne spent much of his childhood in Liverpool, and began composing at a young age. He was educated at Ampleforth College and at Cambridge University, where he worked with Raymond Leppard and Nicholas Maw before spending three years at the Royal Academy of Music as a student of Harrison Birtwistle, Alan Bush and, once again, Maw. During the years 1976 to 1977 he attended several of Olivier Messiaen's classes at the Paris Conservatoire and from 1981 to 1982 made a study visit to the Gambia and southern Senegal – a formative experience he put to creative use as composer-in-residence to the London borough of Hounslow, 1980–83. Together with his second wife, the Ghanaian, Naaotwa Codjoe, he lived in a village near Accra, Ghana, from 1990 to 1996; he has now settled in London. Swayne is a cousin of Elizabeth Maconchy.
 Passage 3:When the Quaker contract expired, Lauck and Goff continued to broadcast on two Texas stations, WBAP (Fort Worth) and WFAA (Dallas). In 1933, The Ford Dealers of America became their sponsor for approximately a year. Horlicks Malted Milk, the 1934–37 sponsor, offered a number of promotional items, including almanacs and fictional Pine Ridge newspapers. During this period, the show was broadcast on Chicago's WGN (AM), one of the founding members of the Mutual Broadcasting System. Effective July 1, 1935, the program was also carried on WLW (Cincinnati, Ohio), KNX (Los Angeles, California), and KFRC (San Francisco, California). Along with The Lone Ranger, Lum and Abner was one of Mutual's most popular programs. In 1936, Dick Huddleston of Waters petitioned the United States Post Office to change the town's name to Pine Ridge. Postum cereal sponsored Lum and Abner in 1938–40, before Alka-Seltzer picked up the duo. Miles Laboratories, manufacturers of Alka-Seltzer and One-A-Day Vitamins, became the longest-running sponsor, backing the program from 1941 until 1948. Over the course of its life, Lum and Abner appeared on all four major radio networks: NBC, Mutual, CBS and ABC (formerly NBC Blue).
