Hi @smilde11, thanks for your post. This stimulus consists of an argument. The environmentalist puts forward the following premises: (1) pollution from gas burned by cars contributes to serious environmental problems; (2) the cost of these problems is not reflected in gasoline prices, so (3) the cost of these problems usually does not affect consumers' decisions about how much to drive. (4) Since heavier taxes on gasoline would reflect this cost - > CONCLUSION: consumers would pollute less.

The question stem asks you to identify the answer choice that is textually supported by this stimulus. Answer choice (C) is correct: it says that "if the cost of the environmental problems to which pollution from driving contributes were fully reflected in the price of gasoline," consumers would drive less and pollute less. Why? Implicitly, because they would purchase less gasoline (because the cost of the gasoline would more accurately reflect the environmental cost of driving).

Hope this helps! Please let us know if you have any additional questions.
