The correct answer is C. Looking for ways to obtain water from the ground
Step-by-step explanation:
Technology is defined as the application of knowledge to create instruments, techniques, etc. with a specific purpose. These purposes include creating instruments to fulfill basic needs such as creating a shelter, finding food, water, etc. In this context, for people living in a desert, like the one shown in the picture, one of the most relevant technological concerns is "Looking for ways to obtain water from the ground" because in this environment bodies of water such as rivers or lakes are scarce and therefore for people to survive they need to create instruments, methods, techniques, etc. to get water from the ground.
