This is not my area of expertise but as far as I understand we refer to a conditioned sound change if a phoneme when in a certain environment becomes another phoneme - there is a certain condition that propells the change. On the other hand we refer to an unconditioned sound change if all phonemes of, for example, two different kinds are merged into one phoneme - there is no condition as it happens in all instances, and ultimately there is a reduction in the number of phonemes as one is substituted for another.

Well I won't write the essay for you but here's what i'll do,
Frankenstein is a novel filled with prejudice. He hopes for friendship with the blind father because he knows that if the blind man could see he would be horrified and be scared of Frankenstein, which would lead to Frankenstein having no friends and being lonely. People judge Frankenstein on his looks, which then label him as a monster. It's the reason why he lashes out at times and is forever angry at everyone because they treat him like the monster he looks like, but not necessarily he acts like a monster. Frankenstein just wants to be treated normal, he wants to have friends and be happy with the way he looks. This theme is relevant to society today because people are often changing the way they look, or wishing they looked another way because people will judge them based on how they look. People self harm, lash out, similiar to what Frankenstein does, and they are treated differently because of how they look.
Something along the lines of that. You can expand the topics as how you see fit. Hope that helps you, comment if you need help with this more. :)
