Question

Read the sentence to determine if it contains an error in parallel structure. If the sentence contains an error, choose "not parallel"; if it does not contain an error, choose "correct."

Most of the difficulties in learning parallel structure arise not from the lack of comprehension of the theory but because examples of good writing are uncommon.
Not parallel or correct.
