Answer 1

Which best explains why viruses are not classified by Linnaean taxonomy?

A. Viruses cannot reproduce outside a host cell and are therefore nonliving.
B. Viruses share many characteristics with several of the kingdoms.

This one has to be A, right? That's the only on that looks right to me.
