Question: Passage: Levette J. Davidson was a nationally acclaimed expert in folklore, especially that of Colorado and the West. He was born in Eureka, Illinois May 16, 1894, one of four children. Because his grand uncle was past-President of Eureka College, a Christian seminary, Davidson was reared in the school's shadow with the option of becoming either a teacher or a preacher. He chose teaching and was awarded his B.A. from Eureka in 1915. A year later he received his A.M. degree from the University of Illinois where he received Phi Beta Kappa honors. In 1917 he earned his M.A. in social science and history at Harvard University. __During World War I, he served with the Tenth Infantry of the Forty-Sixth Division and also served as an army sergeant in Intelligence. Davidson and his wife Mary, also a graduate of Eureka, were married in 1918. At the end of the war, Davidson simultaneously taught and studied at the University of Michigan where he earned a Ph.D. in languages and literatures in 1922. He arrived in Denver later that year and began teaching at the University of Denver. Before arriving in Colorado, his academic specialty was eighteenth century England. Once in Denver, he realized that Western literature and folklore would be his life work. Davidson taught at the University of Denver until his death in 1957. His course topics ranged from studies of Shakespeare and other English literature, to folklore in the West. He began teaching news writing and eventually founded the journalism department at the University as well as the board of publications and the press club. He was the first faculty member elected to serve as president of the University Senate. In 1940 he became head of the English Department and from March to August 1953 he served as interim Chancellor. At the time of assuming his post, he remarked: There is hardly an organization on campus that I have not been connected with at one time or another. Davidson was named University Lecturer for 1956. Davidson was a director of the Colorado State Historical Society, the Modern Languages Association, the American Folklore Society, and the American Dialect Society. He was a charter member of the Denver Posse of the Westerners, an organization devoted to western folklore. In spare moments, Davidson conducted research, wrote outlines for plays, and authored a large number of articles. He contributed to a wide range of magazines from Western American to Shakespeare Quarterly. Additionally, Davidson authored several books on folklore. The most widely recognized is Rocky Mountain Tales, which presents regional folklore as well as true accounts of early events in the area. Levette Davidson died May 14, 1957.

Question: Passage: PA 42 begins at an intersection with PA 61 in the near ghost town of Centralia in Columbia County, which has been largely abandoned because of a mine fire. From PA 61, the route heads north on two-lane undivided Locust Avenue. The road passes through abandoned areas of the town which have been overgrown with trees. The route turns east and crosses into Conyngham Township, becoming South Main Street and heading into forested areas. PA 42 becomes a four-lane road and heads to the northwest, passing through the residential community of Aristes, where it narrows back to two lanes. The road curves to the northeast and becomes Numidia Drive, heading into the Weiser State Forest and turning to the northwest as it crosses Big Mountain. The route turns west and northwest through more dense forests, passing to the east of Shamokin Reservoir. Continuing to the west-northwest, PA 42 enters Locust Township as it crosses Little Mountain, leaving the state forest and turning to the north. The road heads into open agricultural areas with some woods and residences. The route briefly turns northwest before heading north again and passing through the community of Numidia. PA 42 curves to the northwest as it heads through more rural areas, crossing the Roaring Creek and continuing into Catawissa Township. The road runs through a mix of farmland and woodland with some homes, gaining a second northbound lane. The route becomes a four-lane road in a wooded area before turning into a three-lane road with one northbound lane and two southbound lanes. PA 42 comes to an intersection with PA 487, at which point that route joins PA 42 for a concurrency, with the two routes heading north through more woodland as a two-lane road. The road crosses the Catawissa Creek into Catawissa and becomes Mill Street, heading northwest into residential areas. PA 42 splits from PA 487 by heading west-northwest on Main Street, heading through the commercial downtown of Catawissa. The road crosses Norfolk Southern's Sunbury Line before heading across the Susquehanna River, at which point the road becomes Rupert Drive and heads into Montour Township. Here, the route turns north and crosses the North Shore Railroad. PA 42 runs through wooded areas immediately to the west of the railroad tracks with the Susquehanna River a short distance to the east. The road turns north-northwest away from the railroad tracks and heads through the residential community of Rupert. The route passes through more woodland with some homes before reaching an interchange with US 11.

Question: Passage: The western terminus of SR 84 is located at exit 151 on I-8 in southern Arizona. From this diamond interchange, it heads towards the northeast to an intersection with State Route 347 which heads north to Maricopa. SR 84 acts as the southern terminus of SR 347. SR 84 continues east from this intersection passing a large cattle farming facility, home to Shamrock Farms. Immediately east of the cattle farm, SR 84 enters Stanfield acting as the main street through town. Where the first few miles of SR 84 pass through mostly empty desert much of the landscape east of SR 347 comprises agricultural land. East of Stanfield, SR 84 crosses the southern edge of the Francisco Grande golf resort before crossing over a large irrigation canal on a bridge. Just east of the canal, SR 84 enters the outskirts of Casa Grande. SR 84 then proceeds to curve under the Union Pacific Railroad via a highway underpass. SR 84 reaches its signed eastern terminus at a junction with SR 287 (Pinal Avenue) and SR 387 (Florence Boulevard) in downtown Casa Grande at a traffic controlled intersection. Both SR 287 and SR 387 provide connections to Interstate 10 from SR 84's signed terminus.
