PrepTest 54, Section 3, Question 10
Albert: The government has proposed new automobile emissions regulations designed to decrease the amount of polycyclic aromatic hydrocarbons (PAHs) released into the atmosphere by automobile exhaust. I don't see the need for such regulations; although PAHs are suspected of causing cancer, a causal link has never been proven.

Erin: Scientists also blame PAHs for 10,000 premature deaths in this country each year from lung and heart disease. So the proposed regulations would save thousands of lives.

Which one of the following, if true, is the logically strongest counter that Albert can make to Erin's argument?
Most automobile manufacturers are strongly opposed to additional automobile emissions regulations.
It is not known whether PAHs are a causal factor in any diseases other than heart and lung disease and cancer.
Even if no new automobile emissions regulations are enacted, the amount of PAHs released into the atmosphere will decrease if automobile usage declines.
Most of the PAHs released into the atmosphere are the result of wear and tear on automobile tires.
PAHs are one of several components of automobile exhaust that scientists suspect of causing cancer.
