PrepTest 70, Section 2, Question 17
Meteorologist: Heavy downpours are likely to become more frequent if Earth's atmosphere becomes significantly warmer. A warm atmosphere heats the oceans, leading to faster evaporation, and the resulting water vapor forms rain clouds more quickly. A warmer atmosphere also holds more moisture, resulting in larger clouds. In general, as water vapor in larger clouds condenses, heavier downpours are more likely to result.

Which one of the following most accurately describes the role played in the meteorologist's argument by the claim that, in general, as water vapor in larger clouds condenses, heavier downpours are more likely to result?
It is the only conclusion in the argument.
It is the conclusion of the argument as a whole but is not the only explicitly stated conclusion in the argument.
It is a statement that the argument is intended to support but is not the conclusion of the argument as a whole.
It is used to support the only conclusion in the argument.
It provides a causal explanation of the phenomenon described by the conclusion of the argument as a whole, but it is not intended to provide support for that conclusion.
