Can Every Paragraph Be Classified Either as an Argument or as an Explanation

Can every paragraph be classified either as an argument or as an explanation?

A) Yes, because every paragraph either reasons forward from premises to a conclusion or backward from a fact to its cause.
B) Yes, because every paragraph is an explanation of some kind, and arguments are a particular sort of explanation.
C) No, because some paragraphs contain no reasoning at all.
D) No, because some paragraphs provide evidence for a conclusion without making an argument.
E) No, because some paragraphs present reasoning that is too complicated to be called an argument or an explanation.
