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.

Summarize Argument
The author concludes that if Earth’s atmosphere becomes significantly warmer, heavy downpours are likely to become more frequent. This is supported by a causal chain. A warm atmosphere leads to faster evaporation, which leads to rain clouds forming more quickly. A warm atmosphere also leads to more moisture in the atmosphere, which makes clouds larger. The larger, more quickly forming rain clouds result in heavier downpours. This is how heavy downpours are more likely if the atmosphere gets warmer.

Identify Argument Part
The referenced text is offered as support for the conclusion. It’s part of the causal chain that shows how a warmer atmosphere can lead to more frequent heavy downpours.

A

The referenced text is not a conclusion. It’s a premise offered to support the conclusion.
B
It is the conclusion of the argument as a whole but is not the only explicitly stated conclusion in the argument.

C
It is a statement that the argument is intended to support but is not the conclusion of the argument as a whole.
The referenced text is not supported by any other statement. It’s a premise offered to support the conclusion.
D

This accurately describes the role of the referenced text. It is part of the causal chain that is offered to support the conclusion in the first sentence.
E
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.
