I believe the answer is: B. To show that Grendel cannot rely on nature for protection
In the story, Grendel perceive that he is blessed by protection from the nature which would always help him in all of his troubles. But when he somehow got his foot stucked in a tree in front of a bull and when he cried and scream for help from the nature, he did not receive any answer.
Think because ser and hear are the 5 senses and think isn’t related to that.
Hope this helps so 31 animals are walking towards the river right? ok so
1 rabbit + 6 elephants then If every elephant seen 2 monkeys then 6*2 is 12.
= 19 animals.
Then another 12 animals if there is a parrot for every monkey.
19+12 is 31
so your awnser is 31
