Question

What is the structure of the sentence?
The dog wagged its tail and barked when I opened the door.
a. compound
b. compound-complex
c. complex
d. simple

Answer 1

The correct answer is B, because a 'compound-complex clause' consists of two independent clauses (in this case, 1. 'the dog wagged its tail' + AND + 2. '(the dog) barked') and one dependent/subordinate clause ('when I opened the door').
