Concept:Scientific knowledge often develops through unexpected events, not fixed steps. It demands sharp observation and creative thinking.Explanation:The paragraph describes how Dr. Beaumont used an accidental gunshot wound to observe digestion directly. This shows that science does not always follow a strict, pre-planned sequence. Instead, it can arise from unforeseen situations. Beaumont’s careful observation of the stomach’s inner workings and his creative response to the unique opportunity allowed him to gain new insights. Therefore, statement A (science proceeds systematically according to predetermined steps) is not supported because the discovery was opportunistic, not stepwise. Statement B (science requires careful observation and creative response) is clearly illustrated by Beaumont’s actions.Answer:Only B is correct. Hence, option B is the right choice.
