Not sure if this is a good explanation, but this is how I went through it. (it took me a lot of time because I'm reviewing the question type and trying to understand the stim).

Question: Asking about MSS for the evidence cited by the study of traditional narratives.

Stim:

Context: Storytelling is universal (for what) past and present cultures.

Study was conducted on widely separated and diverse areas. (So what?)

The study revealed that from these widely separated and diverse areas that there are common themes that appeared. The study also showed that there are common types of stories that are told.

Summing the stim: From the widely separated and diverse areas, there are common themes and types of stories that appear.

Answer C: Storytellers have long understood that the narrative is a universal aspect of human culture.

Support for Answer C From Stim:

"Story tellers have long understood" I think this derives some support from the context "Story telling is universal for past and present cultures." Past and present implies that the story tellers have long understood. (Don't know if I'm wording this well).

"The narrative" I think this derives support from the study being conducted on traditional narratives.

"There are common themes and types of stories that appear."

I think this part derives the answer from the results of the study that show that there are common themes and common story types that appear.

Another way I thought of this is that from the study, even though it was conducted on areas that were separated and diverse, there are some things in common that they all have.

Chain everything together and you have support for answer C.

I don't know if this helped you understand Answer Choice C, but this is the way I approached the question (with a lot of time). Hopefully this helps you!

I am now thinking constantly in if then statements. If I do this then that will happen and also thinking of the contrapositives. Also, JY as left a mark on me and I always say "So what?!" to drill answers and regular school homework. Hope things go well for you, take it slow and take frequent breaks as you need them. You got this and I believe in you! Hopefully this made someone smile a bit!

Never back down, never give up. I believe in you and all of your abilities. Your score is amazing, you worked hard to study for this test. You should feel proud of your accomplishments, not look down on them. You can't change the past, but you can change the future. I can't necessarily provide any advice to score better or give some reflection points, but I just want to say that I believe in you and you accomplished great things. Best of luck on everything.
