Okay but then how do you conclude? Do you end with your own personal opinion about who holds more power or conclude in the sense that both genders hold power?
'Do you agree' is actually nothing to do with your own viewpoint; if you see a 'do you agree' prompt, rewrite it with 'discuss', because they mean exactly the same thing.
Definitely don't have an essay discussing all viewpoints and then suddenly slam us at the end with 'well actually of the arguments I presented,
this one's right and the others can all go to hell'. If you present multiple viewpoints, that should be your contention, your argument throughout the whole essay: that in most situations X but in some situations Y. Don't introduce something 'new', some new conclusion, at the end - it has to be consistent with your whole essay.
I shall now regurgitate slightly mutated slabs of what I've heard Lauren say, about challenging the prompt. Lauren draws a spectrum that from memory looks something like this:
disagree | X ---------------------*---------------------X---------------------*---------------------X | agree
You have a prompt, and you have to sit somewhere on that spectrum, between 'I 100% agree that in ALL cases for ALL people this is definitely the case' and 'I 100% disagree, this is NEVER the case'. The Xes are bad points to sit. You don't want to fence-sit with 'yeah women don't have much power but actually men don't either and women do have some power, actually it's a bit of both', because it sounds wishy-washy and contradictory. But you don't want to say 'yes all women are always, in every situation, totally powerless', because it's probably not true and as soon as someone can pick one example when women have power, your whole argument collapses.
So, you want to sit at one of the asterisk sweet spots, where you pretty much say, 'Yes, but... [in a few special cases we see...]' or 'No, but...'
'The women of ITCOM are powerless'.
So here, you'll want to think of different characters in the story, and different types of power (physical, power to make their own decisions, power to survive without men, power to influence others' lives, etc.). So your contention may be that while in general women are relatively powerless, they do wield certain types of power in certain circumstances. Plus you should go into the author's intentions and why they present it in a certain way: are they condemning the patriarchal society? are they suggesting that certain characteristics are important to achieve power? etc. You could perhaps go off and talk a bit about how men are powerless, too, but that risks going off topic, because the topic is about women, not men.
Some good structures you could use in your intro or conclusion:
'
Although X,
ultimately Y.'
OR: 'Ultimately for [author], despite X, Y is the case.'
(Where 'X' is your 'but' in a 'Yes, but' or 'No, but' structure).
