When a with/without analysis reveals increased levels of ambient air quality, we can be assured ______________.

Question

Quizplus · Accepted Answer

A with/without analysis compares the situation with a certain policy or action in place versus the same situation without that policy or action. Therefore, if the analysis reveals increased levels of air quality, we can be reasonably assured that the policy or action had a direct impact on improving air quality. Option A is incorrect because the analysis does not provide information on how much money was spent on air pollution control, only on the impact of the policy or action. Option B is incorrect because the analysis does not provide information on the levels of air quality without the policy or action.
