Given the task definition, example input & output, solve the new input case.
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.
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-Lo 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 (18941973) 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.

New input case for you: Question: What is the scientific name of the flowers solitary bees often visit? Passage 1:LCD Soundsystem released "Call the Police" and "American Dream" together as a digital double-A-side single on May 5, 2017, acting as the lead single from the album. The two songs were made available for listening once midnight was reached in one's time zone. The band promoted the songs by performing both during the May 6 episode of the 42nd season of Saturday Night Live. On August 4, the band rolled out an ice cream truck outside of the Lollapalooza festival in Chicago promoting the album. The truck played songs from the album in the form of ice cream jingles through its speaker. A Twitter account for the truck was also launched to provide updates on where its current location was. On August 16, "Tonite" was premiered on Zane Lowe's radio show on Beats 1. Along with the premiere was the release of a music video for the track, directed by Joel Kefali. It was also subsequently made available for streaming on Spotify. A virtual reality experience made to accompany the song, titled "Dance Tonite", was released to the public on August 22, though first previewed privately in June. Available to use in an Internet browser, the experience allowed people with room scale virtual reality kits, such as the Oculus Rift, to dance along to the track. Those with more simpler VR headsets, like the Daydream View, could view the experience as well the dance performances done by others. The band teamed up with the Puckney and Moniker design studios from Amsterdam for the project, alongside Google's data arts team. On August 31, the band released a 14-minute instrumental track called "Pulse (v.1)" as a free download. On Facebook, Murphy wrote that the track was "not precisely part of the record," but instead thought of it as an "addendum" meant to be played after the album's closing track, "Black Screen". It was originally left off of American Dream due to it not being able to fit on the vinyl format of the album. A music video for "Oh Baby", directed by Rian Johnson, was released on September 20, 2018. The video depicts an elderly couple, portrayed by Sissy Spacek and David Strathairn, who build a teleporter in their garage.
Passage 2:Asante began his senior career in England with Birmingham City. He made his first-team debut in the Europa League play-off round second leg against C.D. Nacional in August 2011, and made his debut in the Football League while on loan at Northampton Town in January 2012. He had spells on loan at Shrewsbury Town in both 201213 and 201314, but injury disrupted his progress, and he left Birmingham when his contract expired. Without a club while recovering from injury, he spent the latter part of the 201415 season with Kidderminster Harriers before moving on to Solihull Moors, with whom he won the National League North title. Asante signed for Grimsby Town in January 2017, after missing the first couple of months of 201718 recovering from injury, he went on loan to Solihull Moors, however, he left Grimsby by mutual consent in February 2018. He completed the season with Tamworth, and after a short spell on loan at Chester, he joined them permanently in January 2019.
Passage 3:Anemophilous pollen grains are light and non-sticky, so that they can be transported by air currents. They are typically in diameter, although the pollen grains of Pinus species can be much larger and much less dense. Anemophilous plants possess well-exposed stamens so that the pollens are exposed to wind currents and also have large and feathery stigma to easily trap airborne pollen grains. Pollen from anemophilous plants tends to be smaller and lighter than pollen from entomophilous ones, with very low nutritional value to insects. However, insects sometimes gather pollen from staminate anemophilous flowers at times when higher-protein pollens from entomophilous flowers are scarce. Anemophilous pollens may also be inadvertently captured by bees' electrostatic field. This may explain why, though bees are not observed to visit ragweed flowers, its pollen is often found in honey made during the ragweed floral bloom. Other flowers that are generally anemophilous are observed to be actively worked by bees, with solitary bees often visiting grass flowers, and the larger honeybees and bumblebees frequently gathering pollen from corn tassels and other grains.
