I thought that option D was the correct one because it seemed to me that it related to teacher reflection. However, I did not verify if it was actually mentioned in the text. My mistake was guessing, as I answered without a solid basis. Upon reviewing the text again, I discovered that the correct answer was C, as it focused on analyzing causes, which was what teachers were not doing. This taught me that I cannot just rely on what I think the text says, but must look for concrete evidence.
