Document 3: Hoover Dam: Since about 1900, the Black Canyon and nearby Boulder Canyon had been investigated for their potential to support a dam that would control floods, provide irrigation water and produce hydroelectric power. In 1928, Congress authorized the project. The winning bid to build the dam was submitted by a consortium called Six Companies, Inc., which began construction on the dam in early 1931. Such a large concrete structure had never been built before, and some of the techniques were unproven. The torrid summer weather and lack of facilities near the site also presented difficulties. Nevertheless, Six Companies turned over the dam to the federal government on March 1, 1936, more than two years ahead of schedule.

Document 8: Ghana Bar Association: The British parliament established the Supreme Court of Judicature for the Gold Coast Colony in 1876, with a Chief Justice and no more than four Puisne Justices. John Mensah Sarbah was the first native of Ghana to be called to the bar by Lincoln's Inn in 1887.

As of 2011 there are about 2,500 practicing lawyers, although not all have registered as members of the Bar Association.
