I LOVE THIS TEXT
In the tragedy, 'Medea', Euripides distinctively explores the social differences between men and women in their era, particularly through the actions of the female protagonist, Medea. The actions of Medea defy the conventions of that era, while you do explain that Euripides explores the social inequities between men and women you leave unclear whether or not Medea was trying to emancipate herself or exalt herself to a position where it was possible to commit an act of revenge/justice. This ties in with the prompt - were her actions based on passion? Keep in mind you can argue against the prompt, and in this case I personally would (Hint = there was careful planning from her)
Throughout the play, she is constantly bewailing the disadvantages that women have because of men, imploring their 'wretched' existence. Euripides further portrays this view by representing the men as the logical ones, carefully analysing their decisions before they act, whereas the women are deeply are 'deeply concerned' with their reputation. Excellent use of a quote. Your contention is rather ambiguous; on one note you mention that Medea is constantly complaining, while this is true, it is best to go deeper, such as her being the spokeswomen for women, on the other note men are shown to make logical decisions... however did they allow themselves to be manipulated? (Hint - consider how she managed to get refuge)Keep in mind it is about Jason though.
However, through the Nurse and the Chorus, it is also evident that Jason was initially led by his desires for a more advantageous marriage, this abandoning his family. Its good to mention Euripedes here, maybe best starting the sentence with 'EURIPIDES however, through the USE the Nurse...' This shows that you understand what Euripides is doing. The word 'this' would be replaced with 'thus'.
So you provided an excellent quote.
I think in order to improve your introduction has to be taken a notch higher. For me, its the most important part of the essay. Its the first thing the examiner will judge. Think of it as a first date; chances are you arent gonna get a 2nd date if you arrive unclean or misbehave during it. You want to impress in that date
Just like an essay.. a well versed introduction will make the examiner NOT look for mistakes but the look for the things that emulate your excellent intro.
Your vocabulary is very good, word choice could be better though. Your not in a bad state though, it wont take much to get better at that aspect
Your contentions need to more clear. Think about your 3/4 paragraphs and try to summarize into a sentence or two to put in your intro. It is important to include Euripides as well, as you make the ready acknowledge that you understand what he is conveying across.
The structure isn't A+. You go around a point. As i mentioned its best to go directly with Euripides, or Medea/Jason did this blah blah
