@megmcdermott,This is a great question. "Some" statements are reversible, so yes,
B-some-C could also be written as C-some-B. However, "most" statements
are not reversible, so make sure that you don't reverse those.
The reason "some" statements are reversible is because some means "at
least one" and with B-some-C, you're saying that at least 1 B is a C.
If that's true, then by definition there has to be at least 1 C that's
a B, and that's why we can reverse "some" statements.
Does that make sense? Let us know if you have any other questions!
