Have you ever wondered what our future is like？ Practically all people【C1】______a desire t

o predict their future【C2】______People seem inclined to【C3】______this task u sing causal reasoning. First, we generally【C4】______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 al ways.【C10】______, students learn that studying hard produces good grades【C11】______most instances, but not every time. Science makes these concepts of causality and probability more clear and【C12】______techniques for dealing with them more【C13】______than does causal human inquiry. In looking at ordinary human inquiry, we need to【C14】______between prediction and under .standing. Often, even if we don't under stand why, we are willing to act on the basis of a demonstrated【C15】______ability.

Whatever the primitive drives that【C16】______human beings, satisfying them depends heavily on the ability to predict future circumstances. The attempt to predict is often played in the【C17】______of knowledge and understanding. If you can understand why certain regular patterns【C18】______, you can predict better than if you simply ob serve those patterns. Thus, human inquiry aims【C19】______answering both "what" and "why" questions, and we【C20】______these goals by observing and figuring out.
