The Most Dangerous Game story as two major themes. The first one is reason vs. Instinct and The Effects of War.
On this excerpt, you can see that the theme is reason vs. instinct. The hunter thinks that hunting is a good sport even though it kills an animal that has no way of defending itself. The character Whitney defends that the jaguar has feelings, especially the fear of pain and being killed.
This way this character is used to blur differences between animals and humans, that both have the same feelings.
Superlative means exaggerated.
Comparative means it is being compared to something else.
Positive is self-explanatory.
Honestly this is a hard one because usually when someone says something is "the best" they are exaggerating. Also when you say something is the best, youare saying that the other things you have tasted aren't as good which compares the omelet. Since your not saying the omelet is bad it is a good (positive) comparison. I think the closest answer is comparative for the reasons above.
We are currently reading this in class as well.
Forgive me if I'm wrong, but I believe that the answer is, "They see Dr. Mengele deciding who will live and who will die."
