　　gre改革后新版gre写作新题库里的作文方面的一个重要变化是有了指导语。而指导语的作用是有助于我们的逻辑性写作，以下是新版gre写作新题库内有关argument165的写作部分：

　　题目：

　　Humans arrived in the Kaliko Islands about 7,000 years ago, and within 3,000 years most of the large mammal species that had lived in the forests of the Kaliko Islands were extinct. Previous archaeological findings have suggested that early humans generally relied on both fishing and hunting for food; since archaeologists have discovered numerous sites in the Kaliko Islands where the bones of fish were discarded, it is likely that the humans also hunted the mammals. Furthermore, researchers have uncovered simple tools, such as stone knives, that could be used for hunting. The only clear explanation is that humans caused the extinction of the various mammal species through excessive hunting.

　　Write a response in which you discuss one or more alternative explanations that could rival the proposed explanation and explain how your explanation can plausibly account for the facts presented in the argument.

　　中文翻译：

　　大约7000年前人类到达了Kaliko岛，在3000年内曾经生活在Kaliko岛的树林中的大型哺乳动物绝大多数已经灭绝了。早期的人类学家发现，早期人类主要以鱼类和打猎为生。然而考古学家发现一些有大量鱼骨被抛弃的场所，很有可能人类也扑杀哺乳动物。另外，研究者也发现了一些简单的捕猎工具，例如石刀。显然，哺乳动物灭绝现象的唯一解释就是人类的过度捕杀。

　　写一篇回应，在其中讨论一个或数个可以和文中的解释相竞争的他种解释，并说明你提出的解释是如何可信的解释和说明文中呈现的事实的。
