We focused on key words in the text without interpreting their true meaning. In my case, I chose option B because I interpreted “not rich or detailed enough” as a lack of detail in the methods of reflection, when in fact it referred to understanding the events in the classroom. On the other hand, you selected A by identifying the word “time” in the passage, but the text was not talking about calculating time to reflect, it was talking about deeply analyzing the factors that contribute to the events. To avoid similar mistakes in the future, we should focus on understanding the context and key ideas, not just single words. In addition, carefully re-reading the question and mentally reconstructing what is understood can help us select the correct answer.
