question:
Passage: In the first dismal months of fighting, the Army of the Eastern Pyrenees was beaten at Mas Deu and Bellegarde and forced back under the walls of Perpignan. Then the French repelled two Spanish attacks at Perpignan and Peyrestortes. Though the army was defeated again at Truillas and in other actions, the Spanish invaders withdrew to the Tech River in late 1793. Throughout the year the representatives on mission had enormous powers and used them to interfere with the military effort and to arrest officers that they deemed unpatriotic or unsuccessful. In 1794, the army's fortunes improved when Jacques François Dugommier took command. The army drove the Spanish army from France soil at Boulou and recaptured the Fort de Bellegarde and Collioure. After establishing itself on Spanish territory, the army won a decisive victory at the Battle of the Black Mountain in November during which Dugommier was killed. His replacement, Dominique Catherine de Pérignon soon captured the Sant Ferran fortress and the port of Roses. After these events the front became static and the last notable action was a Spanish victory at Bascara in June.

Marshall), he read for Greats as a second B.A. degree at Oxford in 1965–1967, achieving a First. At Oxford he was taught by, among others, W. G. (George) Forrest, who was a lasting influence. He completed a Ph.D. at Princeton on 'Rome and the Greek world from the earliest contacts to the end of the first Illyrian war', for which Professor J. V. A. Fine was his Advisor; in the preface to that work, he acknowledges the additional inspiration he had drawn from T. J. Luce and the historian and epigrapher C. Bradford Welles. After a spell of teaching at the University of Toronto, he returned to succeed Forrest at Wadham in 1977 when the latter was elected to the Wykeham Professorship of Ancient History at New College. In 2002–2005 Derow was also Director of Graduate Studies in ancient history for the Oxford Faculty of Classics.

Passage: The Lookout Mountain Incline Railway is a inclined plane funicular railway leading to the top of Lookout Mountain from the historic St. Elmo neighborhood of Chattanooga, Tennessee.

It is just a short drive to three of Chattanooga's main tourist attractions, Ruby Falls, Cavern Castle, and Rock City. The railway is approximately in length (single-track except for a short two-track passing loop at the midway point, allowing operation of two cars at one time). It has a maximum grade of 72.7%, making it one of the world's steepest passenger railways. It obtained Historic Mechanical Engineering Landmark status in 1991. The cable system for the cars was made by the Otis Elevator Company.
