The poet laureate consultant, and the librarian of congress eagerly prepare for the new walt whitman exhibit. how is the comma used incorrectly in the sentence above?
the comma attempts to separate a compound subject.
the comma attempts to separate a compound predicate.
the comma attempts to set apart an essential element.
the comma attempts to join two independent clauses.

The correct answer is A. The comma attempts to separate a compound subject.

The comma attempts to separate a compound subject.

Explanation: Everything in this sentence before the adverb "eagerly" is the subject, which consists of two noun phrases that take the verb "prepare." Since there are only two elements in this compound subject, only the conjunction "and" is needed; the presence of a comma before and in this context is confusing, since one usually expects to find such a combination at the end of an independent clause.
