<p>I learned that I should build plywood enclosures in each of my (parents' backyards) so that Rose would be safe year-round. </p>
<p>A. No change
B. parent's backyards
C. parents backyards
D. parents backyards,</p>
<p>You eliminate both C and D. You are left with A and B. I chose B because each parent "owns" a backyard, right? (they are divorced?) But the correct answer is A. Can you please explain why?</p>
<p>P.S. Silverturtle provided an explanation,but I don't understand his reasoning.
