Balanced Sentence:
Construction in which both halves of the sentences are about the same length of importance.


Example:
"It was the best of times, it was the worst of times..." 
-A Tale of Two Cities

Explanation: 
Charles Dickens uses a balanced sentence for many reasons. In this case, this is a balanced sentence with a purpose. The sentence adds suspense, and foreshadows what the novel will be about. The use of a balanced sentence adds to parallelism and creates a certain rhythm that Dickens is known for. This sentence compares to contrasting phrases. Dickens does this on purpose to add to the suspense and show that it is not ine or the other... but in fact, it's both.
