Explanation:
The Los Angeles flood of 1938 was one of the largest floods in the history of Los Angeles, Orange, and Riverside Counties in southern California. The flood was caused by two Pacific storms that swept across the Los Angeles Basin in February-March 1938 and generated almost one year's worth of precipitation in just a few days. Between 113–115 people were killed by the flooding.[1] The Los Angeles, San Gabriel and Santa Ana Rivers burst their banks, inundating much of the coastal plain, the San Fernando and San Gabriel Valleys, and the Inland Empire. Flood control structures spared parts of Los Angeles County from destruction, while Orange and Riverside Counties experienced more damage.[1]
The flood of 1938 is considered a 50-year flood.[2] It caused $78 million of damage ($1.42 billion in 2019 dollars),[2] making it one of the costliest natural disasters in Los Angeles' history.[3] In response to the floods, the U.S. Army Corps of Engineers and other agencies began to channelize local streams in concrete, and built many new flood control dams and debris basins. These works have been instrumental in protecting Southern California from subsequent flooding events, such as in 1969 and 2005, which both had a larger volume than the 1938 flood.[3]

Answer: As soon as Europeans began to settle in America, in the early 16th century, they imported enslaved Africans to work for them. As European settlement grew, so did the demand for enslaved people. Over the next 300 years more than 11 million enslaved people were transported across the Atlantic from Africa to America and the West Indies, and Britain led this trade from the mid-17th century onwards. Ports such as Bristol, Liverpool and Glasgow sent out many slaving ships each year, bringing great prosperity to their owners. Many other cities also grew rich on the profits of industries which depended on slave-produced materials such as cotton, sugar and tobacco.
