Question

What type of clause is shown in parentheses?carla had left a message on the answering machine about (whomever you had spoken to)?

Answer 1

we are given the sentence above and is asked for the type of clause. The clause whomever you had spoken to is dependent since the sentence (original) cannot complete a thought without the clause in this parenthesis. If the sentence otherwise could stand on its own without the clause, then the clause could have been independent.
