我觉得这不是他因削弱。而是直接削弱结论。

推理有一个因果关系，就是价格上升（因）导致了部分出口市场的损失（果）。但是Ａ选项是说对另一种设备的出口需求增长，所以是直接削弱结论的。

有ＮＮ指点么？

(A) The need to comply with the new regulations will stimulate the development within Risemia of new pollution control
  equipment for which a strong worldwide demand is likely to emerge.

对A一直有疑问：

1、R国对国内企业实行减排措施可以促进环保设备制造业的发展，这样的发展可以理解是国内的甚至是国际的。因为在国内需求不能很好的满足的前提下，很多减排企业会进口部分环保设备。

2、R国实施减排不一定会带动其他国家减排，其他国家有什么理由向R国进口呢？这样又怎么会有strong worldwide demand呢？

难道我的思维有问题？

楼上思维确实有问题，作题是基于a这个事实去weaken原题的结论，而不是让你对a本身的合理性质疑。话说回来，我觉得a逻辑也没有什么大问题吧，只是思维方式和考虑问题的出发点不同才会有你这样的问题。比如西方很多人认为环境保护是理所当然的，所以会有这样的固定思维既然是好事大家都会去做。但是国内可能就会不一样，环保成本太高了，所以你们谁爱做谁去做，关我什么事，我只管赚自己的钱。

呵呵，只是个比方

我和eeky想的一样，所以当时看到解释的时候想了好半天。

169. Corporate officers and directors commonly buy and sell, for their own portfolios, stock in their own corporations. Generally, when the ratio of such inside sales to inside purchases falls below 2 to 1 for a given stock, a rise in stock prices is imminent. In recent days, while the price of MEGA Corporation stock has been falling, the corporation's officers and directors have bought up to nine times as much of it as they have sold.

The facts above best support which of the following predictions?

(A) The imbalance between inside purchases and inside sales of MEGA stock will grow
even further.
(B) Inside purchases of MEGA stock are about to cease abruptly.
(C) The price of MEGA stock will soon begin to go up.
(D) The price of MEGA stock will continue to drop, but less rapidly.
(E) The majority of MEGA stock will soon be owned by MEGA's own officers and directors

the ratio of such inside sales 下降，stock prices上升

所以 the price of MEGA 下降 Ratio 9倍于先前的。

那么C中价格M将上升。证明了这 股价将继续上升。

排除法，A imbalance 原文没有讲到。B中 Inside 价格，文中没有强调，无关。

D股价下降，相反。E股票将属于官员，也不对。
