11. “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.
答案是B，但是，B怎么能说是跟生物学家的观点consistent呢？B中并没有言及森林continues to disappear的问题。当然，B也没有反对the biologist’s claim。但是，是否“不反对”在逻辑上就可以叫做consistent，而不一定要完全同意才叫consistent？作者: joywzy 时间: 2003-2-5 20:18 标题: 我是逻辑低手，this is from tongxun
A)politican's opinion
B)it cretainly unfit in the opinoin of politican, but does it fit in that of biologist? yeah! because deforestation is one of the reasons to cause the forest to disappear. Deforestation is a condition made by people, however, others, such as nature fire, and diseases, may also cause the same condition.
C)this chioce is not consistent with both claims
D)consist with politican
E)slowness is not equal to stop. Therefore, it is consitent with that of politican作者: anneanne 时间: 2003-2-10 10:03
