which of the following topics is limited enough for a single paragraph? A. problems that my family has had lately B. different types of used in the world C. what went wrong on my family's last boat trip
I'm saying C, because A says problems plural, as in more than one. B isn't too clear to me. different types of what used? But, it says "different types," as in more than one. Where C reads as if it was one thing that went wrong, therefore there would be less to list, and make it suitable for just one paragraph.
The answer is C.
The other ones are to diverse to capture in a single paragraph.
