问题     Have you ever wondered what our future is like? Practically all people【C1】______a desire to predict their future【C2】______Most people seem inclined to【C3】______this task using causal reasoning. 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 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】______then 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 形容词辨析题。obscure“朦胧的,模糊的”;indistinct“不清楚的”;explicit“外在的,清楚的”;explosive“爆炸的”。该句意思为“科学使因果性和可能性的概念变得更加清晰”,所以用explicit,C为正确答案。
