Question ID:PT33 S1 Q6 Passage:A recent national study of the trash discarded in several representative areas confirmed that plastics constitute a smaller proportion of all trash than paper products do, whether the trash is measured by weight or by volume.  The damage that a given weight or volume of trash does to the environment is roughly the same whether the trash consists of plastics or paper products.  Contrary to popular opinion, therefore, the current use of plastics actually does less harm to the environment nationwide than that of paper products. Stem:Which one of the following, if true, most strengthens the argument? Correct Answer Choice:DChoice A:A given weight of paper product may increase in volume after manufacture and before being discarded as trash. Choice B:According to popular opinion, volume is a more important consideration than weight in predicting the impact of a given quantity of trash on the environment. Choice C:The sum of damage caused to the environment by paper trash and by plastic trash is greater than that caused by any other sort of trash that was studied. Choice D:The production of any paper product is more harmful to the environment than is the production of an equal weight or volume of any plastic. Choice E:The proportion of plastic trash to paper trash varies from one part of the country to another.
