I made a mistake on Question 21 by choosing option B, thinking it aligned with the general idea of reflection as a way to review what had happened. I focused on a specific sentence in the text that mentioned improvement and assumed that B was the correct answer. However, after rereading the passage more carefully, I realized that option C was the better choice. It talked about “thoughtfully examining the possible causes,” which directly reflected the text’s phrase about “reviewing contributing factors in a thoughtful manner.” My mistake was both misinterpreting and misfocusing, as I concentrated on isolated sentences without considering the broader context. I learned that for factual information questions, it’s crucial to pay close attention to the exact meaning of the words and not just rely on an overall impression of the text.
