Is this a parallel sentence? If so how can it be written more simpler.

Question

The space shuttle was both a marvel and huge.

Answer 1

The space shuttle was huge and marvelous.

The problem with the original sentence is that it's trying to use a noun and an adjective to describe the space shuttle. To make it parallel, you need to make both descriptors nouns ... or both adjectives, as I've done above.

Answer 2

The space shuttle was both a marvel and huge.
