Answer:
Parallel structure refers to using the same grammatical form or structure in a series of words, phrases, or clauses in a sentence. This helps to create balance and clarity in your writing.
Example:
Incorrect: She likes hiking, swimming, and to ride a bike. (Inconsistent structure)
Correct: She likes hiking, swimming, and biking. (Parallel structure)
In the correct example, all three activities use the "-ing" form, making the sentence clearer and more balanced.
