Read the following passage and answer the question. When Elena joined the campus debate team, she assumed that winning depended mostly on speaking quickly and confidently. Her coach, however, asked her to spend her first month doing something unexpected: writing down the strongest argument of the opposing side before preparing her own. At first Elena felt frustrated, believing this practice wasted valuable preparation time. By the end of the season, though, she had changed her view. In her final tournament, she paused calmly when an opponent raised a familiar objection, because she had already considered it thoroughly, and then responded with a well-organized counterargument. Judges later commented that her answers showed rare depth for a first-year debater. Elena realized that true confidence comes not from speed but from understanding both sides of an issue. What can be inferred from the passage? A. Elena won her final tournament because she spoke faster than her opponents. B. The coach believed that preparing for opposing views would improve Elena's performance. C. The judges thought Elena should join the team again next year. D. Elena initially refused to follow the coach's advice.
