Answer:
Julie judges people both by their words and by their actions.
Step-by-step explanation:
Parallelism refers to the use of sentence components that are grammatically identical or similar in structure, sound, meaning, or meter. It is considered to be one of the fundamental principles of grammar and rhetoric, adding symmetry, effectiveness, and balance to the text. Examples of parallelism can be found in literary works and everyday conversations alike. A well-known example of parallelism is the Latin saying translated as I came, I saw, I conquered. Here we have the repetition of the past simple tense.
Two sentences we were given are a good example of the presence and the lack of parallelism. There is no parallelism in Julie judges people both by what they say and by their actions. It would've been better had the sentence said Julie judges people both by what they say and by what they do. There we have identical structures. Julie judges people both by their words and by their actions is a good example of parallelism.
