C. Was
It says "my parents or my older sister". The last subject stated is "my older sister" which is singular. And the only choice that's singular is 'was'. So that should be the answer.
Answer:
simple
Explanation:
A simple sentence contains one independent clause with a subject and a predicate. Besides, it makes sense on its own and does not possess any dependent clauses. Thus, even though the subject <em>Joe King</em> is followed by an appositive phrase which identifies him -<em>an engineering professor from California</em>- the sentence still has one single independent clause consisting of a subject and a predicate.
