An essay is more opinionated than a report. while you can give facts and reasons in both, this topic already has a bias towards why it's not important. A report would just state the facts on the importance of cooking, good or bad. While an essay would try to convince you that it's not important and give facts and reasons towards that bias.
Most certainly not internal rhyme because “is” and “june” don’t rhyme The answer is C refrain, because it would start a line or a hole poem. Hope this helps!
