Sagot :
A subordinate clause would be needed to complete this sentence, since with only "My father’s 1969 Volkswagen beetle" we are not getting enough information to form a complete sentence.
Answer:
predicate
Explanation:
Without a predicate, this sentence is nothing more than a noun phrase working as a subject. To have a complete sentence, we need a predicate, that is, the part which introduces the verb linked to this subject. For example: "My father's 1969 Volkswagen beetle hasn't been cleaned in a decade."
