The correct answers are A) to help restore a section of the levee to spare New Orleans from major flooding. C) to cause a breach downstream rather than upstream. D) to provide the flood with a shortcut to the Gulf of Mexico
The reasons behind Governor Simpson's decision were to help restore a section of the levee to spare New Orleans from major flooding, to cause a breach downstream rather than upstream, and to provide the flood with a shortcut to the Gulf of Mexico.
Although you did not include any text, reference, or context, we can say that this question refers to the New Orleans Great Flood of 1927. The governor of the State of Louisiana was O. H. Simpson.
The situation was critical. The government had to make quick and difficult decisions to avoid a catastrophe. The levees were about to break. They considered that if the levees broke south New Orleans, this could mean relief of pressure to avoid the flooding of the city. And that is what they did, at the expense of some flooding in the south side of the city.
