<span>As it turns out, Mrs. Winterbottom leaves to reconnect with a son she gave up for adoption before she married Mr. Winterbottom. She never told anyone about this son for fear of not seeming "respectable." She is very worried about being "respectable," perhaps because Mr. Winterbottom cares so much about being respectable, too.</span>
The correct answer is one main clause.
This means that there is only one verb in the sentence, which in this case is the verb 'was.' Even though drive is also a verb, in this context it is used as an adjective driven (participle form of the verb to drive) and is thus not considered to be a verb. This means that there are no subordinate clauses but rather just one main clause.
