　　Questions 1 to 5 are based on the following passage.

　　Another common type of reasoning is the search for causes and results. We want to know whether cigarettes really do cause lung cancer, what cause malnutrition(營(yíng)養(yǎng)不良), the decay of cities, or the decay of teeth. We are equally interested in effects: what is the effect of sulphur or lead in the atmosphere, of oil spills and raw sewage (污水、污物)in rivers and the sea, of staying up late on the night before an

　　Causal reasoning may go from cause to effect or from effect to cause. Either way, we reason from what we know to what we want to find out. Sometimes we reason from an effect to a cause and then on to another effect. Thus, if we reason that because the lights have gone out, the refrigerator won't work we first relate the effect (lights out) to the cause (power off) and then relate that cause to another effect. This kind of reasoning is called, for short, effect to effect. It is quite common to reason through an extensive chain of causal relations. When the lights go out we might reason in the following causal chain: lights out-power off-refrigerator not working -temperature will rise-milk will sour. In other words, we diagnose (判定)a succession of effects from the power failure, each becoming the cause of the next.
