English Literature essay help!

Hello. I'm new to the forums. I'm still trying to find my way around... but first, I have a question and I would really appreciate any help. I hope I'm allowed to ask for help on homework...

I'm studying five poems: My last Duchess (Browning), Porphyria's Lover (Browning), On my first Sonne (Jonson), The Affliction of Margaret (Wordsworth) and The Man He Killed (Hardy).

I have a choice of three essay questions:

1) What have you found to be of interest in the collection of poems you've studied?
2) What is the effect of the strong narrative voice in the collection?
3) What is the effect of the theme of death/loss in the collection?


I'm utterly stuck on how to go about doing this. Which question would allow me to write the best stuff? I've done some analysis for each individual poem - what the effect of the dramatic monologue is, how enjambement creates a conversational style etc, but I don't know how to answer the question. What sort of things should I include to get good marks? What kind of structure could I use? I know the short answer to these questions, but I don't know how I could develop it.

I have until Thursday to do this. Again, I would really appreciate any help.

Thank you!
