Definition: 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.
Input: Question: Were the two scientists who conducted survey that confirm the length of a metre both born in France? Passage 1:Tatel received his Bachelor of Arts degree from the University of Michigan and his Juris Doctor from the University of Chicago Law School. Following law school, he served as an instructor at the University of Michigan Law School and then joined Sidley Austin in Chicago. Since then, he served as founding director of the Chicago Lawyers' Committee for Civil Rights Under Law, Director of the National Lawyers' Committee for Civil Rights Under Law, and Director of the Office for Civil Rights of the United States Department of Health, Education, and Welfare during the Carter Administration. Returning to private practice in 1979, Tatel joined Hogan & Hartson, where he founded and headed the firm's education practice until his appointment to the D.C. Circuit. While on sabbatical from Hogan & Hartson, Tatel spent a year as a lecturer at Stanford Law School. He also previously served as Acting General Counsel for the Legal Services Corporation.
 Passage 2:When Bart and Milhouse visit the local video arcade at the beginning of the episode, Martin Prince is seen playing an arcade game based on the 1981 film My Dinner with Andre. Other games at the arcade include a game based on the 1984 film The Terminator. The "Springfield, Springfield" number performed by Bart and Milhouse on their night out in town is a reference to the musical number "New York, New York" from the film On the Town, starring Gene Kelly and Frank Sinatra. During a scene in which Hans Moleman and Moe fight with knives, Hans tells Moe, "You call that a knife? This is a knife!", a reference to a line from the 1986 film "Crocodile" Dundee. Ernest Borgnine introduces himself a la Troy McClure to the Junior Campers by recalling his role in From Here to Eternity, a film which modern children are unlikely to have seen. During a hallucination, Homer imagines himself singing the song "Sugar, Sugar" by The Archies while dancing with lollipops and ice cream cones. While on the raft, Homer misquotes lines from Samuel Taylor Coleridge's The Rime of the Ancient Mariner when he says "Water, water everywhere/So let's all have a drink." The scene in which Borgnine and the other rafters drift through a dark forest watched by mountain men is a reference to a scene in the 1972 film Deliverance, and the scene features the music from the film's "Dueling Banjos" scene. The unseen person or creature that attacks Borgnine at the end of the episode is implied to be Jason Voorhees from the Friday the 13th film series.
 Passage 3:Bouguer, La Condamine, Godin and their colleagues measured arcs of the Earth's curvature on the Equator from the plains near Quito to the southern city of Cuenca. These measurements enabled the first accurate determination of the shape of the Earth, eventually leading to the establishment of the international metric system of measurement. When an International Commission for Weights and Measures was convened in Paris to settle the true length of the metre, it adopted on 22 June 1799 a standard metre based on the length of the half meridian connecting the North pole with the Equator. The French Academy of Sciences had commissioned an expedition led by Jean Baptiste Joseph Delambre and Pierre Méchain, lasting from 1792 to 1799, which attempted to accurately measure the distance between a belfry in Dunkerque and Montjuïc castle in Barcelona at the longitude of Paris Panthéon. This portion of the Paris meridian was to serve as the basis for the length of the half meridian connecting the North Pole with the Equator. The metre was defined as the ten-millionth of the half meridian's length extrapolated from a Earth's flattening of 1/334 obtained from the results of the survey by Delambre and Méchain combined with those of the Peru meridian arc as established by La Condamine and his colleagues.
