Answer:
D- acknowledges that her view of living on a farm was limited.
Explanation:
Paragraph 9 is important to the plot because it conveys that Janie acknowledges that her view of living on a farm was limited.
She does acknowledges that when she said "I had no idea of what I was talking about. My farm experience consisted of one field trip..." This shows that her view was limited. This is the reason she was somewhat skeptical about her suggestion to her parents. She felt like her one field trip and the pictures in the book still made her view of living in the farm limited. But it later dawned on her that her suggestion struck a chord in her parents.
