Answer:
to spot the words and sentences that don’t flow well in the essay.
Step-by-step explanation:
Reading the essay out loud is recopmended when revising because it will help you find akward rhytms, repetitive sentence patterns, and missing or not well applied transitions. Remember that when you are writing an essay, the ideas might present one by one, sometimes that is shown in the essay's structure making it slow or without a good flow. Reading out loud makes you see it as a whole, hearing your voice helps you realize how other people will hear it.
