We just atarted a unit on analyzing poetry and I have a few questions I'm not sure of-I have all the terms defined

Question

1. What is the dominant sound device used in this line:
"I all alone beweep my outcast state"
a. alliteration
b.assonance
c.internal rhyme
4.chiasmus
I know its not alliteration but I don't think it repeats vowel sounds but is it an internal rhyme,maybe?
2.What is the dominant figure of speech in this line?
"To laughter and contempt;that she may feel How sharper than a serpent's tooth it is To hav a thankless child! Away, away!
a.alliteration
b.assonance
c. simile
d. metaphor
e. imagery
I know its not metaphor because I originally had that and its not correct-Is it assonance?

Thank you
