The kind of argument used when an author compares water usage in the United States to water usage in poor countries is an appeal to reason.

Explanation:
In this argument, the author is using factual information and logical reasoning to compare the water usage patterns in the United States and in poor countries. The aim is to present a logical case supporting the need for conservation or addressing the disparities in water usage. By highlighting the differences between the two situations, the author wants to persuade the audience to think critically about the issue at hand and make a reasonable assessment. Appeals to reason rely on evidence, facts, and logical explanations rather than relying on emotions or ethical considerations.
