Final answer:
The type of parallelism where the second phrase completes or supplements the first is known as climax. Climax builds up in importance or intensity towards a conclusion, creating impact in writing or speech. OPTION 4 IS ANSWER
Step-by-step explanation:
Parallelism is a rhetorical device used to enhance the fluency and structure of writing. It involves using similar grammatical structures in related phrases or clauses to emphasize an idea and create symmetry and balance.
When a second phrase completes or supplements the first, the type of parallelism being used is typically known as climax. Climax refers to the arrangement of words, phrases, or clauses in an order of increasing importance, often building up to a conclusion or peak.
In the context of rhetorical devices, anaphora is a form of parallelism where the same word or phrase is repeated at the beginning of multiple clauses or sentences to reinforce a concept. Antithesis involves the juxtaposition of contrasting ideas, usually in a balanced structure. Chiasmus is a specific form of parallelism that flips the structure of two parallel phrases.
The increased tension and ultimate resolution that climax provides, make it effective for driving a point home or giving speeches an impactful conclusion. OPTION 4 IS ANSWER
