The answer is the fourth sentence
<span>C. Forgetting where to sit, I wandered around for 10 minutes.
</span>
I would say <span>C. soldier's return to his hometown.
Because it was pretty much saying 6 years without being home, and then he didn't recognized most of the people that were welcoming him home. I mean he obviously does have something to do with the war but it's more about him coming back home.
I hope this helps :)</span>
The answer should be A! Hope this helps :)
