The two best options for Ruth to organize her writing and provide the best structure for her essay are:
Ruth should use the problem-solution structure to show why the dark stories are problematic, and how changing them solves the problem.
Ruth should give examples of the problems that dark stories can cause for younger audiences, and the changes that can solve the problem.
Using the problem-solution structure allows Ruth to clearly identify the issue at hand, which is the darkness of the original folk tales and their appropriateness for children. She can then explore the negative effects or problems that these dark stories can have on younger audiences, such as causing fear or confusion. Ruth can provide specific examples to illustrate these problems, making her argument more persuasive.
After establishing the problems, Ruth can then discuss how changing the stories to be more appropriate for children solves these problems. She can highlight the changes that were made, such as removing or toning down the graphic or disturbing elements, simplifying complex themes, or introducing moral lessons suitable for children. By presenting the solutions, Ruth can demonstrate the rationale behind rewriting the stories and how it benefits the target audience.
This structure allows for a clear progression of ideas, starting with the problems and their effects, and then moving on to the solutions and the positive impact they have on children. It enables Ruth to effectively support her argument and make a compelling case for changing dark, grotesque folk tales into stories suitable for young audiences.
I hope this helps. Cheers! ^^
