Question

Jeffrey wrote an explanatory essay about baseball, but his topic was covered in only one paragraph. What is wrong with his topic?

Answer 1

well first he need more then one parraph

Answer 2

The question is asking what is wrong with the *topic*, not necessarily the way he wrote the topic. Therefore, if he did his due diligence and covered his topic sufficiently, and still ended up with only 1 paragraph, it is likely that his topic is too specific.
