The speaker compares independent clauses to ___ and dependent clauses to ___.

Responses
A adults; childrenadults; children
B children; adultschildren; adults
C adults; marriageadults; marriage
D marriage; adults

A dependent clause is generally seen as less "complete" or unable to stand alone compared to an independent clause, much like a child is usually seen as less independent than an adult. Therefore, more fitting comparison would be:

Independent clauses : adults
Dependent clauses : children

So, the answer that best fits this analogy is:

A adults; children
