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.

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

Now, solve this instance: Question: What is the difference between the amount of gills the species known to prey on the crossback stingaree have compared to most shark species? Passage 1:In April 1980, Hall returned to the US and from 1 to 24 May she appeared in the cast of Black Broadway (a retrospective musical revue) at the Town Hall in New York. Among other artists appearingd in the show were Elisabeth Welch, Gregory Hines, Bobby Short, Honi Coles, Edith Wilson, Nell Carter and John W. Bubbles of Buck and Bubbles fame. The show had originally been staged at the Newport Jazz Festival on 24 June 1979, before it was re-assembled in 1980 and staged at the Town Hall. Following Black Broadway, in June 1980, Hall took up temporary residence at Michael's Pub in New York and commenced a three-week engagement, performing three shows a night. Also in June 1980, she performed at the Playboy Jazz Festival held at the Hollywood Bowl in Los Angeles. Other artists on the bill included Dizzy Gillespie, Herbie Hancock, Stéphane Grappelli, Mel Tormé, Zoot Sims, Carmen McRae and Chick Corea. On 2 July 1980, writer Rosetta Reitz organised a tribute to the Women of Jazz at Avery Fisher Hall as part of the Newport Jazz Festival. Called The Blues is a Woman, the program, narrated by Carmen McRae, featured music by Adelaide Hall, Big Mama Thornton, Nell Carter and Koko Taylor. Back in the States, in February 1983, Hall appeared on the bill of the 100th birthday celebration for composer Eubie Blake held at the Shubert Theater, New York. Unfortunately, Blake was recovering from pneumonia at the time so could not attend the event but with the aid of a special telephone hook-up to his home in Brooklyn he was able to listen to the entire two-hour show. On 5 April 1983, Hall commenced a month-long engagement at the Cookery in New York. Her accompanists were Ronnie Whyte and Frank Tate.
 Passage 2:Kerri Mason of Billboard called the song a harmonious ballad which, along with the single "4 Minutes", "might be some of her best work yet". She also said that the song sounded familiar and compared it with Timbaland's remix of the 2008 single "Apologize". Caryn Ganz from Rolling Stone believed the song has a "melancholy pining". Stephen Thomas Erlewine from Allmusic held the view that "the icy heartbreak of 'Miles Away'" was "a worthy successor of Justin Timberlake's 2006 single 'What Goes Around.../...Comes Around'". Sal Cinquemani of Slant Magazine said that the song has the typical ensuring quality of the production of Timbaland and Justin Timberlake, and bears the "pair's distinct, modern stamp, making Hard Candy more than just a throwback to Donna Summer, Anita Ward, and Quaaludes." Chris William from Entertainment Weekly made the observation that "Miles Away" was one of the "few actual confessions on this dance floor [Hard Candy]—enough to give the tabs speculative fodder." He also compared the song to "What Goes Around.../...Comes Around". Jim Farber of the New York Daily News called it the album's most beguiling tune.
 Passage 3:The broadnose sevengill shark (Notorynchus cepedianus) is known to prey on the crossback stingaree. When threatened, this ray raises its tail warningly above its body in a scorpion-like fashion. Parasites documented from this species include a tapeworm in the genus Acanthobothrium, and the monogenean Calicotyle urolophi. Like other stingrays, the crossback stingaree is aplacental viviparous: when the developing embryos exhaust their supply of yolk, their mother provisions them with nutrient-rich histotroph ("uterine milk") through specialized extensions of the uterine epithelium called "trophonemata". Females produce litters of 1–4 pups every other year. Embryonic development proceeds rapidly over a six-month period, though the total gestation period may be much longer if there is a period of dormancy for the eggs after fertilization, as has been reported in other stingarees. Off Tasmania, large estuaries such as at the mouth of the River Derwent serve as nursery areas.
