Parallelism // Parallel Structure
Parallelism is one of the most common and important concepts tested in the SAT and the ACT. Yet, most of us don’t truly understand the basics of parallelism and take this concept for granted.

verb verb verb

adjective adjective

For example, when you read a sentence like
