Well, using my limited knowledge, "cleaving" means to chop, break in half, split, etc. Twain means twice. So, perhaps it's like "you've broke my heart in half", something along those lines? hopefully this helps you.
I'm gonna say that the answer is C. They valued perseverance, bravery, and strength. and D. They believed the gods were active in peoples lives.
I hope this helps!
