identify the error in the following sentence and the best way to fix it.

Answer:
A. It is a fragment and needs a verb.
Explanation:
A is correct because "All the houses on our block" includes a noun, but not a verb. There is no linking verb that describes what the houses are like. "All the houses on our block are beautiful" is a complete sentence because the word "are" links the ideas "houses" and "beautiful" together.
Answer:
A
Explanation:
The fragment already has a subject, the subject is the houses on "our" block, but we need a verb, what about the houses? what are they doing?
