Question ID:PT60 S1 Q16 Passage:Company spokesperson:  In lieu of redesigning our plants, our company recently launched an environmental protection campaign to buy and dispose of old cars, which are generally highly pollutive. Our plants account for just 4¬†percent of the local air pollution, while automobiles that predate 1980 account for 30¬†percent. Clearly, we will reduce air pollution more by buying old cars than we would by redesigning our plants. Stem:Which one of the following, if true, most seriously weakens the company spokesperson's argument? Correct Answer Choice:CChoice A:Only 1 percent of the automobiles driven in the local area predate 1980. Choice B:It would cost the company over $3 million to reduce its plants' toxic emissions, while its car-buying campaign will save the company money by providing it with reusable scrap metal. Choice C:Because the company pays only scrap metal prices for used cars, almost none of the cars sold to the company still run. Choice D:Automobiles made after 1980 account for over 30 percent of local air pollution. Choice E:Since the company launched its car-buying campaign, the number of citizen groups filing complaints about pollution from the company's plants has decreased.
