A survey recently revealed a high correlation between a household's level of education and its library. Specifically, the more years of college and graduate school education received by the household's members, the more books in the household's library. The survey also indicated that the higher the education level of the household, the greater the percentage of books that are not works of fiction in its library.
Which of the following can be properly inferred from the survey results cited above?
a. People with a higher level of education prefer reading nonfiction to works of fiction.
b. Households with low education levels generally own more works of fiction than do households with high education levels.
c. Households with lower levels of education generally own more works of fiction than nonfiction.
d. The higher the education level of a household, the fewer works of fiction owned by the household.
e. Households with high education levels generally own more nonfiction books than do households with low education levels.
The answer, according to Kaplan, is E. Their reasoning was that [spoiler]Beware of percent questions where there's a difference in the quantities on which the percents are based. Here you know that a highly educated household has a greater number of books than a less-educated household, and a greater proportion of the highly educated household's books are non-fiction. Since a greater proportion of a greater amount is a greater amount, (E) is true — households with high education levels own a greater number of nonfiction books than households with less education.[/spoiler]
However, I can not help but think that "the more years of college and graduate school education received " is QUANTITY and the "the higher the education level" is QUALITY, making none of the answer choices right since they all refer to LEVELS of education, with E comparing quality with quantity.
Is this a poorly written stem or am I missing something?
