Help, Please!

I don't quite understand what is asking in this assignment (Essay)

Task: Write an essay that compares Frankenstein and his creation to a modern zombie story with the focus on how a monster might be used as a metaphor for science or scientific advances and/or how such a metaphor could be considered social commentary about science.

How can I explain/write about the Frankenstein's monster in my first body paragraph?
For my topic sentence is it good if I write something as: Monsters are often symbols of society's anxieties/nightmares, but more importantly the misuse of science and technology.

I really don't know to start it...help! please!

Don't write your topic sentence until you have written the rest of the essay. Do you have a thesis from which to write your essay?
