Question #N770

The process of making a film is long and complex, involving many people with specialized skills. The director is often the key figure, guiding the actors, crew, and other creative personnel toward a shared vision. Even the director, however, must be able to rely on the contributions of others, such as the cinematographer, who determines the look of the film, and the editor, who shapes the narrative structure. Each of these specialists brings a different perspective and set of skills to the project, contributing to the final product.

Which choice provides the best punctuation for the underlined portion of the sentence?
A. contributions, of others; such as the cinematographer, who determines the look of the film, and the editor, who shapes the narrative structure.
B. contributions of others, such as the cinematographer, who determines the look of the film, and the editor, who shapes the narrative structure.
C. contributions of others such as the cinematographer, who determines the look of the film, and the editor, who shapes the narrative structure.
D. contributions; of others such as the cinematographer, who determines the look of the film, and the editor, who shapes the narrative structure.

Correct Answer is: B

The underlined portion is a nonrestrictive appositive phrase, meaning it adds extra information but isn’t essential to the meaning of the sentence. A nonrestrictive appositive phrase must be set off with commas. Semicolons, dashes, or colons are not appropriate in this case.
