Identify the passage that contains a sentence fragment.

A - A child of the fifties who grew up in the suburbs of New Jersey.
Spielberg was part of a group known as the "film school generation"

B - John Hughes was a popular director in the 1980s. Reflecting his upbringing in the Midwest, many of his movies are set there.

C - Following President Kennedy's assassination, Idlewild Airport in New York was renamed John F. Kennedy Airport. The new name became official on December 24, 1963.

D - Many people believe that Rottweilers are dangerous. However, some are being trained as guide dogs.

The fragment part of A is the first part. While this may look like a sentence and may also transmit the same ideas as would a properly formed sentence, this is a fragment.

A sentences fragment is not a sentence because it is not an independent clause containing a subject and a predicate. In order to be a sentence, the fragment would need to be changed to something like the following:

He was a child who grew up in the New Jersey suburbs in the fifties.
