根据材料，完成题。Have you ever wondered what our future is like? Practically, all people 1 a desireto predict their future 2. Most people seem inclined to 3 this task using causal
reasoning.
First, we 4 recognize that future circumstances are 5 caused or conditioned by present ones. We learn that getting an education will 6 how much money we earn
later and that swimming beyond the reef may bring an unhappy 7 with a shark.
Second, people also learn that such 8 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 9 , but not always. Thus, students learn that studying hard 10 good grades in most instances,but not every time. Science makes these concepts of causality and probability more 11 and provides techniques for dealing 12 then more accurately than does causal human inquiry. In looking at ordinary human inquiry, we need to 13 between predicting and understanding. Often, even if we don't understand why, we are willing to act 14 the basis of a demonstrated predictive ability.
Whatever the primitive drives 15 motivate human beings, satisfying them depends
heavily on the ability to 16 future circumstances. The attempt to predict is often played in a 17 of knowledge and understanding. If you can understand why certain regular patterns 18 , you can predict better than if you simply observe those patterns. Thus,human inquiry aims 19 answering both "what" and "why" question, and we pursue
these 20 by observing and figuring out.
