问题     Future prediction enjoys the popularity these days, as traditionally found in Chinese Astrology, and now in online psychic readings, scientific fictions and disaster movies. Have you ever wondered what our future is like? We would badger us about what’s going to happen to us. Practically all people【C1】______a desire to predict their future【C2】______. Most people seem inclined to【C3】______this task using causal reasoning, which is concerned with establishing the presence of causal relationships among events. When we have good reason to believe that events of one sort (the causes) are systematically related to events of some other sort (the effects), it may become possible for us to alter our environment by producing (or by preventing) the occurrence of certain kinds of events.
    First we【C4】______recognize that future circumstances are【C5】______caused or conditioned by present ones. We learn that getting an education will【C6】______how much money we earn later and that swimming beyond the reef may bring an unhappy【C7】______with a shark.
    Second, people also learn that such【C8】______of cause and effect are probabilistic (可能的) in nature. That is, the effects occur more often when the causes occur than when the causes are【C9】______, but not always. Thus, students learn that studying hard【C10】______good grades in most instances, but not every time. Science makes these concepts of causality and probability more【C11】______and provides techniques for dealing【C12】______them more accurately than does causal human inquiry. In looking at ordinary human inquiry, we need to【C13】______between prediction and understanding. Often, even if we don’t understand why; we are willing to act【C14】______the basis of a demonstrated predictive ability. Whatever the primitive drives【C15】______motivate human beings, satisfying them depends heavily on the ability to【C16】______future circumstances. The attempt to predict is often played in a【C17】______of knowledge and understanding.
    If you can understand why certain regular patterns【C18】______, you can predict better than if you simply observe those patterns. Thus, human inquiry aims【C19】______answering both "what" and "why" question and we pursue these【C20】______by observing and figuring out.
【C11】

选项 A、obscure
B、indistinct
C、explicit
D、explosive

答案C

解析 句意理解。原句大意为科学使因果性和可能性的观念变得更加清楚,C项中explicit意为“外在的,清楚的”,符合句意,故为正确答案。obscure意为“朦胧的,模糊的”,indistinct意为“不清楚的”,这两个选项与原句意思相反,应排除;explosive意为“爆炸的”,不符合句意。
