<p>I just took a practice test and need help with this problem. Thanks!
English:
I learned that I should build plywood enclosures in each of my (parents' backyards).
Why wouldnt it be parent's backyards since each lives in his/her own house?</p>
<p>I guess think of it as this: each of us (us is plural)</p>
<p>each of our stuff (our is plural too)</p>
<p>Going off of those examples, a plural thingy (sorry, I don’t know my terms quite well) follows the phrase "each of …).</p>
<p>makes sense. I just confused the fact that phrases that start with “each” have singular verbs not singular nouns haha</p>
<p>parents is a plural noun therefore the ’ comes after the s. If it was one parent it would come before the s.</p>
