College is a new and challenging experience, and new and challenging experience tend to produce stress. Consequently, stress is a common problem that many college students must face. How to reduce stress:
1. Eliminate the source of stress. Identify possible sources of stress, and work toward eliminating them. If a math course is creating stress, for instance, take action. Go to the learning lab or math lab for assistance or inquire about instructions.
2. Establish a daily routine. To eliminate daily hassles (混乱) and make daily tasks as simple as possible, establish a daily routine. A routine eliminates the need to make numerous small decisions, thus giving you a sense of "smooth sailing."

Colds are very common. The symptoms of the common cold include a sore throat, runny nose, stuffed-up nose, and tiredness. Colds are caused by viruses, but scientists cannot explain the exact cause. There is no cure. Many people, however, believe that they know the causes of and cures for the common cold. For example, they believe that it is possible to get a cold if we get chilled, if we get extra tired, or if we are too close to a person with a cold. In other words, if we want to prevent catching cold, we should stay warm and dry; we should avoid getting too tired, and we should not be in close contact with people who have colds.
Meanwhile, there are probably hundreds of " cures" throughout the world for the common cold. For example, the following suggestions are popular in quite a number of societies : (1) drink plenty of water; (2) get extra rest; (3) take a lot of vitamin C; (4) take aspirin; (5) keep warm.
Each year people spend a lot of money on cold medicines-pills, liquids, lozenges (含片). But these medicines do not cure colds; they can only relieve cold symptoms. In other words, they make us feel better.
Which of the following is true about the common cold

A:There are no medicines that c, an cure cold. B:There are hundreds of symptoms of the common cold. C:Many people know what causes the common cold. D:Scientists are close to finding a cure for cold.

? ?Another common type of reasoning is the search for causes and results. We want to know whether cigarettes really do cause lung cancer, what causes malnutrition, the decay of cities, or the decay of teeth. We are equally interested in effects: what is the effect of sulphur of lead in the atmosphere, of oil spills and raw sewage in rivers and the sea, of staying up late on the night before an examination?
? ?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 (refrigerator not working). This kind of reasoning is calls, 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 a succession of effects from the power failure, each becoming the cause of the next.
? ?Causes are classified as necessary, sufficient, or contributory. A necessary cause is one which must be present for the effect to occur, as combustion is necessary to drive a gasoline engine. A sufficient cause is one which can produce an effect unaided, though there may be more than one sufficient cause: a dead battery is enough to keep a car from starting, but faulty spark plugs or an empty gas tank will have the same effect. A contributory cause is one which helps to produce an effect but cannot do so by itself, as running through a red light may. help cause an accident, though other factors--pedestrians or other cars in the intersection—must also be present.
? ?In establishing or refuting (驳倒) a causal relation it is usually necessary to show the process by which the alleged (所谓的) cause produces the effect. Such an explanation is called a causal process.

This passage mainly discusses ______.

A:causal reasoning B:various types of reasoning C:classification of causes D:the causal process
