<h3>What does test procedure?</h3>
A type of clinical trial in which neither the participants nor the researcher knows which treatment or intervention participants are receiving until the clinical trial is over.

Explanation:
All listed scenarios are examples of how people modify the environment in Africa.
When people inhabit a certain territory, they begin to modify it in order to fulfill their needs - to get food and water, build homes, ensure their safety, etc.
In order to get enough food, people need to plant crops. When there is not enough space to do so, sometimes they need to cut down trees. Besides this, wood is a good material for building homes.
If a river is located near these homes and tends to flood the surroundings during the rainy season, people will build dams in order to protect themselves.
Also, people are omnivores, which means that they eat both plants and meat. This is why they keep herd animals that they may later use for meat. These animals need food in order to survive, which is why these people allow them to graze on native grasses.
This is how human-environment interaction works.
