Answer:
Try to explain your research topic more
Step-by-step explanation:
In your paragraphs, make sure there is some form of explanation that goes into the choice of topic in the paragraph itself. You do no want your paragraphs to only be full of facts without some explanation to go with it. If your teacher requires you to, make sure to add citations.
Try not to be repetitive though. If you can possibly add examples to your explanations, it can work out pretty well.
Wish you the best!
