Question

Is the underlined clause independent or subordinate?

Unless he has been left alone, Rover rarely barks or whines.


a. independent
b. subordinate

Answer 1

I will agree with Worldlyglass49, definitely a subordinate clause. B.

Answer 2

Unless he has been left alone - This is a subordinate clause as it needs an independent one to fulfill its meaning and make it correct.

Rover rarely barks or whines - This is an independent clause because it can stand on its own and convey meaning without help from other clauses.
