Complete Question Explanation

Must be TrueX. The correct answer choice is (E).

The main point of this paragraph, from the first sentence, is that nature regulates the atmospheric carbon level:
  • More carbon :arrow: more heat :arrow: more evaporation :arrow: more rain :arrow: carbon washed from air

    Less carbon :arrow: less heat :arrow: less evaporation :arrow: less rain :arrow: less carbon washed from air
The author argues that although a sustained increase in the carbon level would be dangerous, natural regulation of atmospheric carbon levels should put environmentalists’ minds at ease.

Because this is an “EXCEPT” question, we need to look for the answer choice that is not dictated to be true by the stiumulus.

Answer choice (A): This is accurate, as we can see from the causal chain above.

Answer choice (B): This is also accurate.

Answer choice (C): This is accurate, so it is not the exception we are looking for either.

Answer choice (D): This is a proper inference as well.

Answer choice (E): This is the correct answer choice. It represents a mistaken reversal. A decrease in carbon causes a decrease in the level of atmospheric heat, not the other way around.
