Which sentence is a subordinate clause

Joseph proposes to her

Because George does not understand beneath a

Beneath a moves to Africa

Mama pays for a new house

The answer is: Because George does not understand

A subordinate or dependent clause cannot stand alone because it does not express a complete thought. It begins with a relative pronoun or a subordinate conjunction (like because), and contains a subject and a verb.

Subordinate clauses need to be connected to an independent clause in order to make sense. For instance, a complete version of the example subordinate clause followed by an independent clause is:

Because George does not understand, he cannot solve the Maths problem.
