Exercise Can Replace Insulin for Elderly Diabetics

    Most older people with so-called type H diabetes could stop taking insulin if they would do brisk exercise for 30 minutes just three times a week, according to new medical research results reported in the Copenhagen newspaper Berlingske Tidende on Monday.
    Results from tests conducted on diabetics at the Copenhagen Central Hospital Rigshospitalet"s Center for Muscle Research showed that physical exercise can boost the body"s ability to utilise insulin by 30 per cent, the newspaper reported.
    This is equal to¹ the effect most elderly diabetics get from their insulin medication today，it said.        ‘、
    Researchers had a group of non-diabetic men and a group of men with type n, all more than 60 years of age, exercise on bicycles six times a week for three months. After the three months the doctors measured how much sugar the test subjects" muscles could utilise as a measure for how well their insulin worked.²
     Associate Professor³ Dr. Flemming Dela of the MuscleResearchCentersaid the tests demonstrated that the exercising diabetics had just as high insulin utilisation as the healthy non?exercising persons.
    "This means that the insulin works just as well for both groups. Physical exercise cannot cure people of diabetes,⁴ but it can eliminate almost all their symptoms. At the same time it can put off⁵ the point at which they have to begin taking insulin or perhaps completely avoid insulin treatment，” Dela was quoted as saying.⁶
    Insulin isa hormone produced by the pancreas，controlling sugar in the body and used against diabetes.
　　Dela said that to achieve the desired effect diabetics need only exercise to the point where they begin to work up⁷ a sweat, but that the activity has to be maintained since it wears off⁸ after five days without sufficient exercise.
　　Most diabetics realise that they have to watch their diet while remaining unaware of⁹ the importance of exercise, Dela added.

? ?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.

According to the passage, to do the "effect to effect" reasoning is to reason ______.

A:from cause to effect B:from effect to cause C:from effect to effect and on to cause D:from effect to cause and on to another effect
