Step-by-step explanation:
The quote suggests that life's greatest lessons are learned B) at the worst times and from the worst mistakes. This idea is echoed in the saying, "By three methods we may learn wisdom: first, by reflection, which is noblest; second, by imitation, which is easiest; and third by experience, which is the bitterest." It implies that through challenging experiences and the reflection upon errors made, individuals gain profound understanding and wisdom. Moreover, the life course for individuals within a culture encompasses not just the passage of time but also the lessons they must learn, which are often the result of navigating through life's difficulties and learning from poor decisions. Education, with its broad range of exposure to different subjects and the cultivation of critical self-examination, plays a key role in developing one's ability to learn from life's experiences.
