Is this a high school essay, or Uni?
This isn't an Introduction. You've launched straight into some superficial comparisons and observations: "...however, the men brushed them away as if they had no merit to the case. This is an example of sexism."
Are you aware that "Trifles' was written in 1916? The play depicts the life of a woman who has been suppressed, oppressed, and subjugated by a patronizing, patriarchal husband. Other male characters see females on a purely stereotypical, gender-related level.
Mrs. Wright is eventually driven to kill. As such, the play has been regarded as an early feminist work, with the female no longer tolerating her oppression. The men have all the power, and she is forced to violence.
In the other book, Connie has (or hasn't) been raped. Male power with violence. How does she react? How do other men react to this? As opposed to the 'reality' of the Glaspell play, this book has been regarded as a feminist allegory.
We've got power and sexual politics here.
I can't detect in your "Introduction" what the thesis is that you will be arguing.
I had a hunt on the Internet - there are some sites with dime novel approaches to Introduction writing - and came up with this:
Essay question: "Is the present level of immigration in the United Kingdom beneficial to the country?"
Immigration is an emotive subject which is seldom out of the news. The recent rise in immigrants in the United Kingdom from the new European Union countries has refocused debate on this controversial issue. It is a topic which is difficult to explore because of the lack of hard data and the preponderance of anecdotal evidence. Nevertheless, the areas of controversay have centred on how this has impacted, for better or worse, on employment prospects, British culture, and race relations.
Can you see that it doesn't start, "I think that immigration has been beneficial..."!!! or start listing pros and cons. As a serious 'academic' piece, it doesn't employ the oft-recommended approach of shock tactics and some sensational atttention-grabbing emotive opening statement.
It takes an overall look, gives a framework, introduces the idea of its effect - for better or worse (and so setting up the essay for discussion of how it is beneficial or not) - and the areas in which this will be discussed.
