25. Which of the following were ways that the Mesopotamians and Egyptians changed their environment to suit their needs? (2 points, choose 2)

The Mesopotamians and Egyptians made significant alterations to their environments for agricultural and economic purposes. Here are two ways they did this:

1. **Irrigation Systems**: Both Mesopotamians and Egyptians developed extensive irrigation systems to control the flow of water from rivers (like the Tigris and Euphrates in Mesopotamia and the Nile in Egypt) to their fields. This allowed them to support agriculture in areas that would otherwise be too dry or less fertile.

2. **Soil Management**: They engaged in practices such as plowing and fertilizing the soil to improve crop yields. In Egypt, the annual flooding of the Nile deposited rich silt on the fields, which was used to enhance farming productivity.

These methods enabled them to transform their environments into productive agricultural lands, supporting their civilizations.
