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.
For what battle was Houston used as an organization point ?

Answer: Battle of Galveston

Problem: Their first ever defeat on home soil to a foreign team was an 02 loss to the Republic of Ireland, on 21 September 1949 at Goodison Park. A 63 loss in 1953 to Hungary, was their second defeat by a foreign team at Wembley. In the return match in Budapest, Hungary won 71. This still stands as England's worst ever defeat. After the game, a bewildered Syd Owen said, "it was like playing men from outer space". In the 1954 FIFA World Cup, England reached the quarter-finals for the first time, and lost 42 to reigning champions Uruguay.
After reaching the FIFA World Cup quarter-finals for the first time, to whom did England lose with a final score of 4-2?

Answer: Uruguay

Problem: William Henry Perkin studied and worked at the college under von Hofmann, but resigned his position after discovering the first synthetic dye, mauveine, in 1856. Perkin's discovery was prompted by his work with von Hofmann on the substance aniline, derived from coal tar, and it was this breakthrough which sparked the synthetic dye industry, a boom which some historians have labelled the second chemical revolution. His contribution led to the creation of the Perkin Medal, an award given annually by the Society of Chemical Industry to a scientist residing in the United States for an "innovation in applied chemistry resulting in outstanding commercial development". It is considered the highest honour given in the industrial chemical industry.
What was coal tar derived from?
