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.
One 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.

Now, solve this: Question: Who commanded the 32nd Virginia Volunteer Infantry Regiment when Goggin joined the Confederacy? Passage 1:In 1861, Goggin moved back to Virginia, entering the Confederate States Army on July 1, 1861 as a major in the 32nd Virginia Volunteer Infantry Regiment where he was assigned to lead a battalion. Goggin and the 32nd Virginia Infantry served under Maj. Gen. John B. Magruder in 1861 and into 1862 during the Peninsula Campaign. Goggin joined the First Corps, Army of Northern Virginia in April 1862, serving on the staff of Maj. Gen. Lafayette McLaws as his assistant adjutant general. He served in this capacity during all of the First Corps' engagements, in both the Army of Northern Virginia and the Army of Tennessee, until the spring of 1864. During the Battle of Fort Sanders in November 1863, Goggin carried a message from McLaws to Lt. Gen. James Longstreet, informing him that the attack was beginning to fail and it was futile to carry in on. When McLaws was replaced with Maj. Gen. Joseph B. Kershaw in May 1864, Goggin served as his assistant adjutant general as well. His service in this post was highly praised by Goggin's superiors.

 Passage 3:Lake Minchin was a saltwater lake, which covered the basins of the Salar de Uyuni, Salar de Coipasa, Lake Poopo and Salar de Empexa, including the towns of Llica, Oruro and the Desaguadero River valley. The lake had an extension of in east-west direction and of in north-south direction. A sill at Ulloma separated Lake Minchin from Lake Titicaca. Water levels reached an altitude of above sea level, indicating a depth of above the Uyuni basin. In the Poopo basin, water levels may have reached . At Cerro Lipillipi terraces between are dated between 25,700 and 31,750 BP. Another estimate is . Earlier estimates of the altitude are , resulting in depths of . Such water heights exceed these of preceding lakes, and together with even higher water levels of the subsequent Lake Tauca they are part of a trend of increasing water levels in the southern Altiplano which contrasts with progressively decreasing lake levels in the northern Altiplano. Earlier research suggested an opposite trend of lowering water levels in both basins. The surface area of Lake Minchin may have been , or . A lake terrace at is also attributed to Lake Minchin. The highest lake terraces at and were later found to belong to Lake Tauca, making it the deeper of the two lakes. If Minchin reached a water level of it may have spilled into the Pilcomayo River, draining from there via the Rio de la Plata into the Atlantic Ocean. It is also possible that the lake temporarily drained into the Pacific Ocean through its southwesternmost sector at Salar de Ascotán; such an outlet would have existed for only a brief time, however, before it was obstructed by volcanism. San Agustin, San Cristobal and Colcha formed islands in the lake, which was separated into a Coipasa half and an Uyuni half by a peninsula of the Serranía Intersalar; straits at Llica and Salinas de Garci Mendoza connected the two halves. Bays developed close to Isluga, Empexa and Ollagüe.
