Explanation:

To determine which quotation supports the conclusion about efficient resource use, we analyze each option:

• Option A: Discusses human height, not resource use. Eliminate.
• Option B: Describes creating check dams and channels to direct rainwater (a limited resource) to crops, showing efficient use of water for farming. This matches the conclusion.
• Option C: Talks about living location change, not resource use. Eliminate.
• Option D: Discusses leaving Mesa Verde, not resource use. Eliminate.

Answer:

B. However, the farmers were expert in dryland farming, creating check dams and channels to direct rainwater to their crops. (paragraph 10)
