The skylights, that were made with aluminum leafing, indicate the time period in which the Great Hall was constructed. How is th
e comma used incorrectly in the sentence? A) The comma attempts to set apart an essential element. B) The comma attempts to separate a compound subject. C) The comma attempts to separate a compound predicate. D) The comma attempts to join two independent clauses.
The correct answer to this question is letter ". C) The comma attempts to separate a compound predicate."
The first part of the sentence is the predicate, so it's not trying to separate a subject.
"Then skylights that were made of aluminum siding" isn't a sentence, so it's not an independent clause."
