Question

The plants in my garden wilted because they could not take the summer heat (identity main clause and subordinating clause)​

Answer 1

Answer:

A subordinate clause is a clause that cannot stand alone as a complete sentence; it merely complements a sentence’s main clause, thereby adding to the whole unit of meaning. Because a subordinate clause is dependent upon a main clause to be meaningful, it is also referred to as a dependent clause.

Answer 2

Answer: To find the main clause in a sentence, look for a subject and a verb. Once you've identified these, see if the clause would make sense as a stand-alone sentence. If this is the case then you've probably found the main clause.
