OG16 CR50 看不太懂OG的解释

芊层酥

Some anthropologists study modern-day societies of foragers in an effort to learn
about our ancient ancestors who were also foragers. A flaw 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, nonforager
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.



(D) Many anthropologists who study modern-day forager societies do not
draw inferences about ancient societies on the basis of their studies.


答案是A，但我不懂D为什么是错的。
我的思路是这样的：科学家不应该通过学习现代捕猎社会来理解古代捕猎社会，因为
1. 捕猎社会特别变化多样，2. 而且科学家熟悉的都是现代、非捕猎社会。
A没错，是说捕猎社会特有许多共同特征
但D也说了，科学家并不会通过现代捕猎社会来进行推断啊，所以并不会受影响。

是因为D只weaken了第二个论据吗？

提前感谢！

问题问的是most weaken the criticism   

批评学家认为“forager societies are extremely varied”，且现代的forager society和现在的nonforager societies接触多。所以study modern-day societies of forager无价值，不能和 ancient societies of foragers 相比
   
要weaken，就是说 “就算society varied也有研究的价值”  

a 提到了相同之处，

d 无关选项，人类学家的basis不是critic的点，而且没有基于研究做出什么推理，和原文也没什么关系

支持楼上观点
d里面有个many，通常cr提到some或者many都表示一部分，相对的，另外一部分可以通过研究现代的forage来总结，那么d就没谈到点子上，我认为为无关选项
