18. We commonly speak of aesthetic judgments as subjective, and in the short term they are, since critics often disagree about the value of a particular contemporary work of art. But over time, the subjective element disappears. When works of art have continued to delight audiences for centuries, as have the paintings of Michelangelo, the music of Bach, and the plays of Shakespeare, we can objectively call them great.
The statements above best support which of the following conclusions?
(A) When Michelangelo, Bach, and Shakespeare were alive, critics disagreed about the value of their work.
(B) The value of a contemporary work of art cannot be objectively measured.
(C) The reputation of a work of art often fluctuates greatly from one generation to the next.
(D) The mere fact that a work of art has endured for centuries does not establish its greatness.
(E) If critics agree about the value of a particular cotemporary work of art, then the work can objectively be called great.

(B) Highway driving at 55 miles per hour or less is more fuel-efficient than high-speed driving.

(D) The percentage of fatalities occurring in highway accidents at speeds greater than 55 miles per hour is higher than that for low-speed accidents.
(E) Automobiles last longer and require fewer repairs when driven at consistently lower speeds.
