The level of sulfur dioxide in the atmosphere is slightly higher than it was ten years ago. This increase is troubling because ten years ago the Interior Ministry imposed new, stricter regulations on emissions from coal-burning power plants. If these regulations had been followed, then the level of sulfur dioxide in the atmosphere would have decreased.

Summary
Ten years ago, stricter regulations on power plant emissions were imposed.
If those regulations had been followed, the level of sulfur dioxide in the atmosphere would have decreased.
The level of sulfur dioxide in the atmosphere has increased over the last ten years.

Very Strongly Supported Conclusions
The emissions regulations have not been followed.

A
If current regulations on emissions from coal-burning power plants are not followed from now on, then the level of sulfur dioxide in the atmosphere will continue to increase.
Unsupported. The level of sulfur dioxide increased because the regulations were not followed, but we don’t know what might happen if the regulations are not followed from now. Sulfur dioxide might continue to increase, or it might level out, or something else might reduce it.
B
There have been violations of the regulations on emissions from coal-burning power plants that were imposed ten years ago.
Very strongly supported. If the regulations had been followed, the level of sulfur dioxide in the atmosphere would have decreased. But the level of sulfur dioxide has increased, so the regulations must not have been fully followed.
C
If the regulations on emissions from coal-burning power plants are made even stronger, the level of sulfur dioxide in the atmosphere still will not decrease.
Unsupported. The stimulus doesn’t tell us anything about what might happen if regulations are made stronger. We only know that if the original regulations had been followed, then sulfur dioxide levels would have decreased.
D
Emissions from coal-burning power plants are one of the main sources of air pollution.
Unsupported. Power point emissions caused an increase in the level of sulfur dioxide in the atmosphere, but we don’t know that they’re one of the main sources of air pollution.
E
Government regulations will never reduce the level of sulfur dioxide in the atmosphere.
Unsupported. The regulations imposed ten years ago didn’t successfully reduce the level of sulfur dioxide in the atmosphere, but that doesn’t mean that government regulations will never reduce it.
