Question

Which of the items below is the whole main clause in the following sentence? I had to cancel the class because it was snowing to hard.

Answer 1

The main clause is: I had to cancel the class.  It is the main clause, because it can stand alone. It has a subject (I) and a verb (had to cancel) and expresses a complete thought- I had to cancel the class. 

 

Hope that helped.

Answer 2

I had to cancel the class.
