So this is actually a question. I'm new to the site and still figuring out how things work. Can I answer a question that someone else has answered? Is there a case where this is not possible? I am seeing a lot of people post links to the answer and I am too wary to open them. These cannot be acceptable answers can they?

Yes you are able to answer questions, but if someone else has already answered it I don't think you are able to answer bececause I have been experiencing the same problem. And I am not sure about the links aswell.

the correct answer option is b. a single paragraph.

explanation:

when you are thinking about paragraph​ topics, you should always choose a subject that can be adequately addressed in a single paragraph.

a paragraph is a piece of writing consisting of a few sentences that deal with a single theme. it has only a single idea that the paragraph revolves around and talks about.

so a paragraph topic must be chosen wisely where a single idea can be communicated in a single paragraph.
