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 old was the railway that was laid on Wheatfield road in 1894? Passage 1:Along with adjacent Newton County, Searcy is unique among Arkansas counties in being traditionally Republican in political leanings even during the overwhelmingly Democratic "Solid South" era. This Republicanism resulted from their historical paucity of slaves, in turn created by infertile soils unsuitable for intensive cotton farming, and produced support for the Union during the Civil War. These were the only two counties in Arkansas to be won by Alf Landon in 1936, Wendell Willkie in 1940, Charles Evans Hughes in 1916, and even Calvin Coolidge in 1924. In Presidential elections post-1932, Harry S. Truman and Jimmy Carter are the only Democrats to carry the county. In the 1992 election George H. W. Bush won his second-highest margin in the state, and the Republican nominee has received over 60 percent in Presidential elections from 2000 to 2012 inclusive. In 2016, Searcy County voted over 79 percent for Donald Trump, while former Arkansas First Lady Hillary Clinton received just 16 percent.
Passage 2:During the Battle of Gettysburg, the dirt Wheatfield Road was used by various Union and Confederate troops (e.g., Crawford's Third Division of Pennsylvania Reserves), and Union troops deployed artillery westward to the Peach Orchard using the road. In 1884, the Round Top Branch's wye with double spurs and station was built at the east end of Wheatfield Road, and in 1894 the Gettysburg Electric Railway was laid along a west portion of the road (trolleys also crossed the east end near Round Top Station). In 1895, the Commonwealth of Pennsylvania ceded jurisdiction of Wheatfield Road to the War Department, and in 1900 two cast iron identification tablets were placed to label the road. The Gettysburg Electric Railway tracks were removed from the Wheatfield Road in 1917 and the road was repaired in 1931. The Wheatfield Road was resurfaced with asphalt west of Sykes Avenue in 1933, and completed "from the Rosensteel pavilion to the Taneytown road" in 1940 by the McMillan Woods Civilian Conservation Corps camp.
Passage 3:Rigden was editor of the American Journal of Physics from 1975 to 1985. In 1987, he joined the American Institute of Physics, where he served as Director of Physics Programs. In 1992, he was appointed Director of Development of the National Science Standards Project at the National Academy of Sciences. In 1995, he was elected chairman of the History of Physics Forum of the American Physical Society (of which he was a fellow). He also served on committees for the American Association of Physics Teachers, the American Physical Society, the American Association for the Advancement of Science (of which he was also a fellow), and the National Academy of Sciences. He served as a National Science Foundation (NSF) consultant to the country of India in 1968 and again in 1969. He was the United States Representative to the International Science Exhibition in Rangoon Burma in 1970. He was also a Fulbright Fellow to Burma in 1971 and to Uruguay in 1975.
