Which of the following is a compound subject?


cats and dogs
twenty-two miles
cats or dogs
each girl or boy

my answer

cats and dogs

Right.

Your answer is correct! "Cats and dogs" is a compound subject because it contains two or more subjects joined by the conjunction "and." To identify a compound subject, look for multiple subjects joined by words like "and," "or," or "nor." In this case, "cats" and "dogs" are both subjects in the sentence.
