There is often a fierce rivalry between the two strongest teams in a national league, and this is particularly the case in La Liga, where the game between Barcelona and Real Madrid is known as El Clásico. From the start of national competitions the clubs were seen as representatives of two rival regions in Spain: Catalonia and Castile, as well as of the two cities. The rivalry reflects what many regard as the political and cultural tensions felt between Catalans and the Castilians, seen by one author as a re-enactment of the Spanish Civil War.
What kind of tensions are the two teams viewed as displaying?

Since the university's establishment in the city in 1837, the histories of the University of Michigan and Ann Arbor have been closely linked. The town became a regional transportation hub in 1839 with the arrival of the Michigan Central Railroad, and a north—south railway connecting Ann Arbor to Toledo and other markets to the south was established in 1878. Throughout the 1840s and the 1850s settlers continued to come to Ann Arbor. While the earlier settlers were primarily of British ancestry, the newer settlers also consisted of Germans, Irish, and African-Americans. In 1851, Ann Arbor was chartered as a city, though the city showed a drop in population during the Depression of 1873. It was not until the early 1880s that Ann Arbor again saw robust growth, with new immigrants coming from Greece, Italy, Russia, and Poland. Ann Arbor saw increased growth in manufacturing, particularly in milling. Ann Arbor's Jewish community also grew after the turn of the 20th century, and its first and oldest synagogue, Beth Israel Congregation, was established in 1916.

West's breakthrough came a year later on October 23, 2002, when, while driving home from a California recording studio after working late, he fell asleep at the wheel and was involved in a near-fatal car crash. The crash left him with a shattered jaw, which had to be wired shut in reconstructive surgery. The accident inspired West; two weeks after being admitted to the hospital, he recorded a song at the Record Plant Studios with his jaw still wired shut. The composition, "Through The Wire", expressed West's experience after the accident, and helped lay the foundation for his debut album, as according to West "all the better artists have expressed what they were going through". West added that "the album was my medicine", as working on the record distracted him from the pain. "Through The Wire" was first available on West's Get Well Soon... mixtape, released December 2002. At the same time, West announced that he was working on an album called The College Dropout, whose overall theme was to "make your own decisions. Don't let society tell you, 'This is what you have to do.'"

At the completion of the west front in 1140, Abbot Suger moved on to the reconstruction of the eastern end, leaving the Carolingian nave in use. He designed a choir that would be suffused with light. To achieve his aims, his masons drew on the several new features which evolved or had been introduced to Romanesque architecture, the pointed arch, the ribbed vault, the ambulatory with radiating chapels, the clustered columns supporting ribs springing in different directions and the flying buttresses which enabled the insertion of large clerestory windows.
What portion of the reconstruction of Saint Denis was begun after the completion of the west front?
