Is this a trick question?
The point of using opossum is to point out that people will eat whats available. Asians typically eat things not consumed in the West. Just as people in the west eat things they wouldn’t think of in Asia.
After WWII South Korea was decimated and there was very little food. There weren’t any cows and few pigs for people to eat. What did exist was far too expensive.
I’m sure the people of North Korea would love to have a fido or two.
“Is this a trick question?”
Depends on how you define “is” in the sentence!
