Q11 “If the forest continues to disappear at its present pace, the koala will approach extinction,” said the biologist.

“So all that is needed to save the koala is to stop deforestation,” said the politician.

Which one of the following statements is consistent with the biologist’s claim but not with the politician’s claim?

(A) Deforestation continues and the koala becomes extinct.

(B) Deforestation is stopped and the koala becomes extinct.

(C) Reforestation begins and the koala survives.

(D) Deforestation is slowed and the koala survives.

(E) Deforestation is slowed and the koala approaches extinction.

我觉得答案是D, B应该说明显错的，是不是答案有误？

Q18. Learning how to build a nest plays an important part in the breeding success of birds. For example, Dr. Snow has recorded the success of a number of blackbirds in several successive years. He finds that birds nesting for the first time are less successful in breeding than are older birds, and also less successful than they themselves are a year later. This cannot be a mere matter of size and strength, since blackbirds, like the great majority of birds, are fully grown when they leave the nest. it is difficult to avoid the conclusion that they benefit by their nesting experience.

Which one of the following, if true, would most weaken the argument?

(A) Blackbirds build better nests than other birds.

(B) The capacity of blackbirds to lay viable eggs increases with each successive trial during the first few years of reproduction.

(C) The breeding success of birds nesting for the second time is greater than that of birds nesting for the first time.

(D) Smaller and weaker blackbirds breed just as successfully as bigger and stronger blackbirds.

(E) Up to 25 percent of all birds are killed by predators before they start to nest.

答案是B，不过我怎么觉得一个都不对阿？B说，在开始几年里，随着每次造窝成功，下蛋能力也增加，不是有加强作用吗？

Despite improvements in treatment for asthma, the death rate form this disease has doubled during the past decade from its previous rate. Two possible explanations for this increase have been offered. First, the recording of deaths due to asthma has become more widespread and accurate in the past decade than it had been previously. Second, there has been an increase in urban pollution. However, since the rate of deaths due to asthma has increased dramatically even in cities with long-standing, comprehensive medical records and with little or no urban pollution, one must instead conclude that the cause of increased deaths is the use of bronchial inhalers by asthma sufferers to relieve their symptoms.

Q22. Each of the following , if true, provides support to the argument EXCEPT:

(A) Urban populations have doubled in the past decade.

(B) Records of asthma deaths are as accurate for the past twenty years as for the past ten years.

(C) Evidence suggests that bronchial inhalers make the lungs more sensitive to irritation by airborne pollen.

(D) By temporarily relieving the symptoms of asthma, inhalers encourage sufferers to avoid more beneficial measures.

(E) Ten years ago bronchial inhalers were not available as an asthma treatment.

这题我确觉得A，B好像都可以。A不能说是surpport，但B可是直接否定题中的条件，应更不surpoort才对。答案是A

谢谢
