To reduce the danger to life and property posed by major earthquakes, scientists have been investigating several techniques for giving advance warning of dangerous earthquakes.  Since catfish swim erratically before earthquakes, some investigators have proposed monitoring catfish to predict dangerous earthquakes.
 
Which of the following, if true, most seriously undermines the usefulness of the proposal?

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, non-forager societies.

Which of the following, if true, would most weaken the criticism made above of the anthropologists’ strategy?
不是很明白原文在讲大概是什么内容，感觉每个选项都不对

During the past year, Pro-Tect Insurance Company's total payouts on car-theft claims were larger than the company can afford to sustain.  Pro-Tect cannot reduce the number of car-theft policies it carries, so cannot protect itself against continued large payouts that way.  Therefore, Pro-Tect has decided to offer a discount to holders of car-theft policies whose cars have antitheft devices.  Many policyholders will respond to the discount by installing antitheft devices, since the amount of the discount will within two years typically more than cover the cost of installation.  Thus, because cars with antitheft devices are rarely stolen, Pro-Tect's plan is likely to reduce its annual payouts.
 
In the argument above, the two portions in boldface play which of the following roles?
虽然已经有很多解答录音，但是我还是有一点疑问。 做题过程：A选项读完没什么太大感觉，留着； BE第二个不是CON，杀；C，读完原文，第一句黑体说的是Pro-Tect不能怎么怎么样，因此只能采取第二句黑体的方法；D自己做题的时候需 觉得D和C意思挺像的，杀D的原因是第一句话是一个consideration，觉得不太算是evidence 想问C错在了哪里？说一种方法不行不是把另外的路堵死了，对现在的方法的一种支持吗？ 拜托老师解答~

Journalist: In physics journals, the number of articles reporting the results of experiments involving particle accelerators was lower last year than it had been in previous years. Several of the particle accelerators at major research institutions were out of service the year before last for repairs, so it is likely that the low number of articles was due to the decline in availability of particle accelerators.

Which of the following, if true, most seriously undermines the journalist's argument?
老师，这题我错选了D.我是觉得既然是要驳斥particle accelerators引起文章数量减少，那么D中说它在多组实验中使用，那文章数量不一定会减少。请问如何停止这种发散？
