题目
Unless tiger hunting decreases, tigers will soon be extinct in the wild. The countries in which the tigers’ habitats are located are currently debating joint legislation that would ban tiger hunting. Thus, if these countries can successfully enforce this legislation, the survival of tigers in the wild will be ensured.
The reasoning in the argument is most vulnerable to criticism on the grounds that the argument
选项
A.assumes without sufficient warrant that a ban on tiger hunting could be successfully enforced
B.considers the effects of hunting on tigers without also considering the effects of hunting on other endangered animal species
C.fails to take into account how often tiger hunters are unsuccessful in their attempts to kill tigers
D.neglects to consider the results of governmental attempts in the past to limit tiger hunting
E.takes the removal of an impediment to the tigers’ survival as a guarantee of their survival
解析
除非老虎捕猎活动减少,否则老虎很快就会在野外灭绝。老虎栖息地所在的国家目前正在讨论联合立法来禁止老虎捕猎。因此,如果这些国家能够成功执行这项立法,老虎在野外的生存就能得到保证。
- **核心论点**:论据是通过立法禁止老虎捕猎且能成功执行,论点是老虎在野外的生存就能得到保证。即认为禁止捕猎这一行为就必然能确保老虎野外生存,将禁止捕猎这一有利于老虎生存的条件视为老虎生存的充分条件。
- **正确答案方向**:正确答案应该指出这种推理的不合理之处,即仅仅解决捕猎这一个问题并不一定能完全确保老虎在野外的生存,可能还有其他影响老虎生存的因素未被考虑。
- **A选项**:虽然该选项指出了执行禁令可能存在的问题,但这并不是原论证最根本的逻辑漏洞,原论证的主要问题在于把禁止捕猎当成了老虎生存的充分条件,而不是能否执行的问题,所以A选项不正确。
- **B选项**:题干讨论的是老虎的生存问题,与其他濒危动物物种无关,该选项属于无关选项,所以B选项错误。
- **C选项**:老虎捕猎者捕猎成功的频率高低与原论证的核心逻辑漏洞无关,原论证的核心是关于禁止捕猎能否必然保证老虎生存,所以C选项不合适。
- **D选项**:过去政府限制老虎捕猎的尝试结果与当前论证禁止捕猎就能确保老虎生存这一逻辑关系不大,所以D选项也不正确。
- **E选项**:该选项准确地指出了原论证把消除老虎生存的一个障碍(禁止捕猎)当作了老虎生存的保证,即指出了原论证将必要条件当成充分条件这一根本逻辑错误,所以E选项正确。
综上所述,答案是E选项。
