结论是说要增加收入。问题是要削弱结论。条件是因为虫害导致棉花价格升高继而导致了O 国家的农民要种植棉花赚钱。C说某个杀虫剂可以控制虫害，这样棉花的产量不就上去了？那价格还会涨吗？

而且文章也没有说需求啊。

你看错了，你说的选项是B

是要削弱结论或者从前提推出结论的过程，明显者各过程存在漏洞，因为原题中没有提过会有高收入，只说有搞价格，所以如果过去的时间里，搞价格没有带动高需求，也就没有了高收入，那些农民是根据过去到现在的事实判断的，这样一来，他们的判断不正确，因此采取措施效果也就不一定好了

mgq

Although most people know that the exercise is good for the body, few realize the extent to which it is valuable to the mind. The blood circulates more rapidly after the physical exertion, thus allowing all of the body's organs to operate more efficiently. This increased activity enables brain to receive more oxygen, thereby creating a higher capacity for concentration.

The main point in the argument above is that

1. the greater the amount of oxygen brain receives, the better it functions.

2. Exercise is a mental as well as physical activity.

3. Exercise helps the brain more than it does the rest of the body.

4. people can greatly improve their powers of concentration by exercising more often.

5.exercise serves more than one purpose.

唉！！犯晕了

mgq

A certain drug, when taken by patients with high blood pressures, was found to lower the blood pressure to high-normal levels, or from an average of 30 percent to an average of 10 percent above normal. However a survey of patients with normal blood pressures found that almost 80 percent exercised atleast 5 days per week for 30 minutes and maintained a normal blood pressure.
Therefore, the drug is not as affective in reducing blood pressure in patients with high blood pressure as is exercise. The validity of the above conclusion depends on the truth of which of the following ?

A.None of the patients with high blood pressure exercise regularly.
B. No patient with high blood pressure successfully achieved below-normal levels with drug alone.
C. Patients with normal blood-pressure maintained healthy diets for the duration of the study.
D. Daily exercise has the same effect on the blood pressures in all patients.
E. The drug has little or no effects on patients with normal blood pressures.
