Having studied small engine repair in night school, fixing the lawn mower was easy was a incomplete comparison.

Answer: D

Explanation

A sentence is not complete when it has a dangling modifier.

This means that there is no action or subject in the sentence.

As a result, dangling modifiers occur due to wrong punctuation.

When you put a period in before the statement is complete, and then it will result in a fragment.

Further when writing a sentence while omitting one or 2 subject; you will be creating a fragment within that sentence.

Therefore in the given case, there is no subject.
