43. Some anthropologists study modern-day societies of foragers in an effort to learn about our ancient
ancestors who were also foragers. Aflaw in this strategy is that forager societies are extremely varied.
Indeed, any forager society with which anthropologists are familiar has had considerable contact with
modern, non-forager societies.
Which of the following, if true, would most weaken the criticism made above of the anthropologists' strategy?
(A) All forager societies throughout history have had a number of important features in common that are
absent from other types of societies.
(B) Most ancient forager societies either dissolved or made a transition to another way of life.
(C) All anthropologists study one kind or another of modern-day society.
(D) Many anthropologistswho study modern-day forager societies do not draw inferences about ancient
societies on the basis of their studies.
(E) Even those modern-day forager societies that have not had significant contact with modern societies are
importantly different from ancient forager societies.

我理解 天下乌鸦一般黑 老鼠的儿子会打洞 所以叫：have had a number of important features in common 就可以weaken啦

？  请问这是什么意思呢 我没有看的很懂  谢谢

maestri

题目有三元素：1：modern-day societies of foragers  2：ancient ancestors foragers 3：modern, non-forager societies
题干意思：科学家通过研究1了解2，有人批评 因为1和3有联系，所以不能通过1了解2
A选项指出1和2的必然联系，所以这种研究方法是正确的，削弱了题干中的批评声音

“天下乌鸦一般黑 老鼠的儿子会打洞”指的就是古代与现代的必然联系啦！

不好意思才看到您的回复啊 我根据您的意思写的逻辑链是

P： 1→2
P： 1 有关于3

C：所以 1→2 FLAW

感觉这个题目有GAP 在 2 3 之间虽然是个WK题
