Researchers hope to find clues about the A’mk peoples who lived in the Kaumpta region about one thousand years ago but who left few obvious traces. The researchers plan to hire the few remaining shamans of the modern-day indigenous people in Kaumpta, who are believed to be descended from the A’mk, to lead them to ancestral sites that may be the remains of A’mk buildings or ceremonial spaces. The shamans were taught the location of such sites as part of their traditional training as youths, and their knowledge of traditional Kaumpta customs may help determine the nature of any sites the researchers find.

研究人员想要找到一些关于A’MK人的线索，1000年前的A’MK人生活在Kaumpta地区，但是他们几乎没有留下什么痕迹。研究者计划去雇佣一些Kaumpta地区现存的萨满，这些人被认为是A’MK人的后代，让这些萨满将研究者带到祖先的遗址（那里可能是A’MK人之前居住的遗址或者是仪式场所）。这些萨满在年轻的时候就被训练过这些地点的所在位置，而且他们对于Kaumpta地区传统知识的了解可能会有助于帮助研究者对所发现的遗址进行更好地研究。

解析：找出上述计划的前提条件，即雇佣当地萨满确实有助于研究者去找到一些A’MK人的线索。

Which of the following is an assumption on which the success of the plan depends?

A. The researchers have reliable evidence that the A’mk of one thousand years ago built important ceremonial spaces.

研究者有可靠的证据表面A’mk人在1000年前建造了重要的仪式场所，属于无关信息，与上述计划的内容无关，可以排除。

B. The shamans have a reasonably accurate memory of A’mk sites they learned about as youths.

这些萨满是通过在年轻时的训练记住遗址地点的，如果说他们的记忆很准确，那么可以进一步支持计划的可行性；如果他们记忆会有不准确的情况出现，那说明计划的实施会存在问题。因此，该选项为正确答案。

C. Kaumpta shamans are generally held in high esteem for their traditional knowledge.

萨满在当地地位的高下与上文的计划无关，可以排除。

D. Modern technologies available to the researchers are likely to be able to find some A’mk sites easily.

该选项说明现代设备就可以帮助研究者去找到遗址，质疑了上述推断，因此排除该选项。

E. Most or all A’mk sites are likely to be found within the Kaumpta region.

大部分或者是所有A’mk的地址都可能会在Kaumpta地区被发现，上述计划并未强调遗址在Kaumpta地区内，因此属于无关信息，可以排除。
