PROBLEM: By 1860, Houston had emerged as a commercial and railroad hub for the export of cotton. Railroad spurs from the Texas inland converged in Houston, where they met rail lines to the ports of Galveston and Beaumont. During the American Civil War, Houston served as a headquarters for General John Bankhead Magruder, who used the city as an organization point for the Battle of Galveston. After the Civil War, Houston businessmen initiated efforts to widen the city's extensive system of bayous so the city could accept more commerce between downtown and the nearby port of Galveston. By 1890, Houston was the railroad center of Texas.

SOLUTION: What commodity was Houston known for in 1860? 

PROBLEM: With the opening of the Dorothy and Michael Hintze sculpture galleries in 2006 it was decided to extend the chronology of the works on display up to 1950; this has involved loans by other museums, including Tate Britain, so works by Henry Moore and Jacob Epstein along with other of their contemporaries are now on view. These galleries concentrate on works dated 1600 to 1950 by British sculptors, works by continental sculptors who worked in Britain, and works bought by British patrons from the continental sculptors, such as Canova's Theseus and the Minotaur. The galleries overlooking the garden are arranged by theme, tomb sculpture, portraiture, garden sculpture and mythology. Then there is a section that covers late 19th-century and early 20th-century sculpture, this includes work by Rodin and other French sculptors such as Dalou who spent several years in Britain where he taught sculpture.

SOLUTION: Who were the sculpture galleries that opened in 2006 named after?

In the Balkans, the Ottoman Empire, a Turkish state originating in Anatolia, encroached steadily on former Byzantine lands, culminating in the Fall of Constantinople in 1453.

SOLUTION:
