20 read the paragraph. excessive homework is a problem. students have too much work. teachers assign homework to . however, homework doesn’t learning. homework equates to busy work. students can learn without it. what is the best way to revise this paragraph? vary sentence length eliminate redundant words fix the balance of details add a topic sentence

The correct answer would be A: Vary sentence length. As you can see when you read the paragraph, there are lots of short sentences that are ended with periods one after another. It isn't correct to write the paragraph the way they have written it, so they can change it by replacing some periods with commas and adding some new words to make better sentences. Hope this helped! :)

Vary sentence length in my opinion. it all kind of sounds like a robot there is a topic sentence and the details are fine. there is also no need to eliminate anything.
hope this helps!
