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-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.

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

Now, solve this: Question: How many years after the Equal Protection Clause was created was it used to strike down anti-miscegenation laws? Passage 1:The time from roughly 15,000 to 5,000 BC was a time of transition, and swift and extensive environmental change, as the planet was moving from an Ice age, towards an interstadial (warm period). Sea levels rose dramatically (and are continuing to do so), land that was depressed by glaciers began lifting up again, forests and deserts expanded, and the climate gradually became more modern. In the process of warming up, the planet saw several "cold snaps" and "warm snaps", such as the Older Dryas and the Holocene climatic optimum, as well as heavier precipitation. In addition, the Pleistocene megafauna became extinct due to environmental and evolutionary pressures from the changing climate. This marked the end of the Quaternary extinction event, which was continued into the modern era by humans. The time around 11,700 years ago (9700 BC) is widely considered to be the end of the old age (Pleistocene, Paleolithic, Stone age, Wisconsin Ice Age), and the beginning of the modern world as we know it.
Passage 2:The right to marry a person of a different race was addressed in Loving v. Virginia, in which the Court said, in 1967, that its decision striking down anti-miscegenation laws could be justified either by substantive due process, or by the Equal Protection Clause. The unconstitutionality of bans on and refusals to recognize same-sex marriage was decided partly on substantive due process grounds by Obergefell v. Hodges in 2015. A right to have children was addressed in Skinner v. Oklahoma, but the Court in Skinner, in 1942, explicitly declined to base its decision on due process but instead cited the Equal Protection Clause since the Oklahoma law required sterilization of some three-time felons but not others. A substantive due process right of a parent to educate a young child (before ninth grade) in a foreign language was recognized in Meyer v. Nebraska, in 1923, with two justices dissenting, and Justice Kennedy has mentioned that Meyer might be decided on different grounds in modern times. Laws that "shock the conscience" of the Court were generally deemed unconstitutional, in 1952, in Rochin v. California, but in concurring, Justices Black and Douglas argued that pumping a defendant's stomach for evidence should have been deemed unconstitutional on the narrower ground that it violates the Fifth Amendment's right against self-incrimination. The Court, in O'Connor v. Donaldson, in 1975, said that due process is violated by confining a nondangerous mentally ill person who is capable of surviving safely in freedom. Chief Justice Burger's concurring opinion was that such confinement may also amount to "punishment" for being mentally ill, violating the Court's interpretation of the Eighth Amendment in Robinson v. California. Freedom from excessive punitive damages was deemed to be a due process right in BMW v. Gore, in 1996, but four justices disagreed. The Court, in Cruzan v. Missouri, decided, in 1990, that due process is not violated if a state applies "a clear and convincing evidence standard in proceedings where a guardian seeks to discontinue nutrition and hydration of a person diagnosed to be in a persistent vegetative state".
Passage 3:Truls Ove Karlsen (born 25 April 1975 in Oslo) is a retired Norwegian alpine skier. He made his Alpine Skiing World Cup debut in Solden in 2001. He made a total of 143 World Cup starts, finishing third in a slalom in Sestriere in December 2002 and scoring his only World Cup win in a slalom in Kranjska Gora in February 2004, leading home team-mate Tom Stiansen in a Norwegian one-two ahead of Austrian Mario Matt. His best World Cup seasons were 2003 and 2004, where he finished eighth in the slalom standings. His best results at the Alpine Skiing World Championships were achieved at the 2007 Championships in Are, where he finished sixth in the giant slalom and seventh in the slalom. He represented Norway at the 2010 Winter Olympics. Karlsen announced his retirement from competition in February 2013. Since then he has worked as a personal trainer. He graduated from the Norwegian University of Science and Technology with a bachelor's degree in History and Psychology in 2004, and started studies for a master's degree in law at the University of Oslo in 2013.
