Hey Thesmartblonde!
Beowulf's self assurance is revealed when he refuses to use weapons to fight the monster Grendel. He is confident and believes in his ability to fight and win against Grendel, without having to use any weapons! Therefore the answer to your question is, B.
Hope this helps!
I believe the answer is A, to. When there is a prepositional phrase, think about "Anywhere a mouse can run" A mouse can't run 'meet' or 'hard' or 'worked', but it can run 'to'. :)
One is the runners were a rumbling herd. I'm not quite sure about a second metaphor. I hope at least this helped.
