Parallel structure means having the same importance and grammatical styles used for a series of words, phrases, or clauses in a sentence. A writer who makes an error in parallel structure can confuse readers and inadvertently make the story less entertaining.
The experience is similar to getting lost on a twisted highway that intersects and overlaps with other unmarked roads. Clearly marked streets that run parallel to one another are much easier to navigate—and they give you time to enjoy the scenery. For authors, parallel structure is a serious matter.
When you write with parallel structure, you use the same tense and structure for your verbs. (Keep an eye out for errors in parallel structure in your own writing.)
Now, let's address the question: Which sentence correctly uses parallel structure? <em>Which sentence uses the same tense and structure for your verbs?</em>
Well, obviously it's Choice A:
"My friends never judge me by my actions or my statements."
It uses the same tense and structure for the verbs "actions" and "statements."
Therefore, the answer is: Choice A.
