Q: 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.
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 Sölden 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 Åre, 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.
