Research on the reintroduction of large carnivores such as bears and wolves has implications both for the modern-day debate over the appropriateness of reintroduction programs and for the historical debate over what happened 10,000 to 50,000 years ago when one particular predator, human beings, expanded their territory and encountering large numbers of native prey.
human beings, expanded their territory and encountering
human beings, expanded their territory to have encountered
the human being, expanded its territory and encountered
the human being, had expanded its territory to encounter
the human being, had expanded their territory and encountered
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
还是不能理解为什么expand和encounter不能并列。人类也可以是因为其他目的去expand然后恰巧encounter了更多的动物。CD时态不同，能讲下这句怎么从时态判断吗？
这是一个挺好的问题。一定要从设置GMAT这个考试的逻辑上来思考这个问题。GMAT不想让我们成为语言学家，而是想考查我们的逻辑思维能力，所以我们要选择逻辑上最合理的选项。这道题目中，“扩大领土”和“遇到更多猎物”之间至少不应该是并列，这是两个完全不同层级的动作。例如：
我们可以说：
小明去跑步并且去跳绳。
但一般不说：
小明去跑步并且去锻炼身体。
第二个例句会被理解为跑步并不是锻炼身体。虽然你也可以说，跑步“恰好”锻炼了身体，但逻辑上并不是最好的。
尽量不要从时态的角度来判断考题，尤其是在过去时和过去完成时之间选择。因为从原则上来说，如果我们想突出是过去的过去，那就用过去完成时，但如果不想突出，就可以直接用过去时。所以，判断起来，非常随性。

Bi, can you stop justifying your ignorance?
According to the context , we can hardly assume the very intention of human being is to encounter more prey, nor should we justify the usage of "HAD done" .
In case of any refutation, here is the origin.
The research, which was published in the Feb. 9 issue of the journal Science, has implications both for the modern-day debate over reintroduction programs and for a historical debate over what happened 10,000 to 50,000 years ago, when one particular predator, humans, expanded its territory and encountered large numbers of native prey. Some experts think that a ''blitzkrieg'' of killing by advancing humans contributed to the extinctions of many large animals in that era.
See, It's an article from NY Times. what I wanna say is stop offering your misguidance and misinterpretation!
Yeah, I think you are right. Good for you.
这道题，我觉得毕老师的解释有点问题。首先，一个人很难在一两分钟的时间判断出扩大领土是为了打猎这样的逻辑；其次，when后面使用had done的时态是有问题；最后，扩大领土和打猎为什么不能并列呢，I went to the playground and palyed basketball. 这样没有问题。
哇 你英文真棒 go read NY times then.. did he charge you ? stupid ass free rider
你说得很棒，bichu的题还是将就看看，和og还是有差别的
