Cinema Studies Student: A film critic argues that modern moviegoers lack the patience that was common among moviegoers in the silent era. The critic must be correct, because in her analytical study of 20 popular modern movies, she found the average length of a scene to be less than half as long as the average length of a scene in 20 popular movies from the silent era; longer scenes try audience's patience.

Which of the following points to a possible flaw in the student's argument?

A
There may be more relevant criteria than the average length of a movie scene by which to evaluate the interest of modern moviegoers in silent films.
B
The student may not have agreed with the critic's conclusion had she watched the movies herself.
C
The critic could have chosen to analyze a set of movies that supported her hypothesis.
D
Some filmmakers deliberately use shorter scenes to enhance the drama of their work.
E
A moviegoer unfamiliar with cinema studies may not understand the critic's methodology in determining average scene length.
