Three years ago, because of flooding at the Western Palean Wildlife Preserve, 100 lions and 100 western gazelles were moved to the East Palean Preserve, an area that is home to most of the same species that are found in the western preserve, though in larger numbers, and to the eastern gazelle, a close relative of the western gazelle. The only difference in climate is that the eastern preserve typically has slightly less rainfall. Unfortunately, after three years in the eastern preserve, the imported western gazelle population has been virtually eliminated. Since the slight reduction in rainfall cannot be the cause of the virtual elimination of western gazelle, their disappearance must have been caused by the larger number of predators in the eastern preserve.

请问这道题的提纲是不是就是罗列各种其他可能导致灭绝的原因
谢谢

不是这么回事的，题目的结论是说导致灭绝的原因是由于是捕食者的原因，你要做的是指出他得到这个结论的不合理之处，就是它的条件是不是成立的，它的推导是不是合理的，你所说的只是一部分，你所说的要紧紧抓住题目中提到的东西，而不是自己去想其他的东西等等
