Have you ever wondered what our future is like? Practically all people【B1】______a desire to predict their future 【B2】______. Most people seem inclined to 【B3】______ this task using causal reasoning. First we 【B4】______ recognize that nature circumstances are 【B5】______ caused or conditioned by present ones. We learn that getting an education will【B6】______how much money we earn later and that swimming beyond the reef may bring an unhappy 【B7】______ with a shark.Second, people also learn that such 【B8】______ of cause and effect are probabilistic in nature. That is, the effects occur more often when the causes occur than when the causes are【B9】______, but not always. Thus, students learn that studying hard【B10】______good grades in most instances, but not every time. Science makes these concepts of causality and probability more【B11】______and provides techniques for dealing 【B12】______then more accurately than does causal human inquiry. In looking at ordinary human inquiry, we need to【B13】______between prediction and understanding. Often, even if we don't understand why, we are willing to act【B14】______the basis of a demonstrated predictive ability. Whatever the primitive drives【B15】______motivate human beings, satisfying them depends heavily on the ability to【B16】______future circumstances. The attempt to predict is often played in a【B17】______of knowledge and understanding. If you can understand why certain regular patterns【B18】______, you can predict better than if you simply observe those patterns. Thus, human inquiry aims 【B19】______answering both "what" and "why" question, and we pursue these【B20】______by observing and figuring out.
