It's a nonessential word, clause, or sentence added to an already grammatically complete sentence. It's most commonly set off by brackets, but it can also be set off by commas or dashes. 
Example: 
My mother went to the supermarket and picked up some strawberries (my favorite fruit) earlier today.
        
             
        
        
        
The sentence in which parallel structure is used is A) While making a necklace, Sharon strung sparkly beads, added heart charms, and attached a silver clasp.
The parallel structure is marked in this sentence because the <em>simple past tense </em>is used in the three clauses. The parallel structure, also known as parallelism, is <em>the use of a repetitive pattern in the sentence structure. </em>Its function is to give an equal importance to different ideas or words within a sentence. The use of parallelism is useful to balance writing and make a sentence easier to read. One way of balancing a sentence is to use the same tense in all clauses. The other sentences B, C and D <em>do not follow a repetition in pattern.</em>
