PrepTest C2, Section 2, Question 3
Agriculture researcher: Because of its slow decomposition, paper is ineffective as a mulch to guard against soil erosion. However, a mixture of paper and manure, which decomposes faster than paper alone, is very effective. When spread over test plots, the mixture significantly decreased the amount of soil erosion. Since paper costs roughly the same as manure, farmers would be better off using this mixture than paper or manure alone.

The agriculture researcher's argument is flawed because it provides no evidence that
paper by itself does not contribute to soil erosion
mulch containing paper and manure works better than mulch containing only paper
mulch containing paper and manure works better than mulch containing only manure
mulch containing paper and manure works better than methods of preventing soil erosion that do not involve mulch
mulch of pure manure provides nutrients to the soil that paper mulch does not
