The dream of space travel became a reality.
how does the word reality function in the sentence?

as a predicate adjective

as an object complement

as an indirect object

as a predicate nominative

The answer is a predicate nominative.

Explanation:

Let`s split this sentence into its basic parts: subject (the dream of space travel), predicate (became a reality).

Now let`s analyze predicate closely:

it consists of a verb (linking verb) and a noun that modifies and explains it.

Since it`s a noun, the correct answer is a predicative nominative.

Of course, if the adjective was next to the predicate, the answer would be a predicate adjective.

its is b

explanation:

the reason it is b is because b is in third person saying destiny chose this so therefore it is b
