Question: 84

18.

Which is a valid conclusion, based on the graphs alone?

A. More students majored in English in 2000 than in 1995.
B. More students majored in business in 1995 than in 2000.
C. History was the most popular major in 1995.
D. Fewer students majored in economics in 1995 than in 2000.
E. In 2000, more students majored in engineering than in English.

Correct Answer: E

Explanation:

E. Well, Choice (C) is obviously false, judging by the first graph. Choices (A), (B), and (D) all suffer from the same problem: You have no idea how many students attended State U in 2000. Comparing the number of people in each major in the two different years is impossible. The second graph shows that Choice (E) is true.
