Editorial:
Regulations recently imposed by the government of Risemia call for unprecedented reductions in the amounts of pollutants manufacturers are allowed to discharge into the environment. It will take costly new pollution control equipment requiring expensive maintenance to comply with these regulations. Resultant price increases for Risemian manufactured goods will lead to the loss of some export markets. Clearly, therefore, annual exports of Risemian manufactured goods will in the future occur at diminished levels.
Which of the following, if true, most seriously weakens the argument in the editorial?
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.
The proposed regulations include a schedule of fines for noncompliance that escalate steeply in cases of repeated noncompliance.
Savings from utilizing the chemicals captured by the pollution control equipment will remain far below the cost of maintaining the equipment.
By international standards, the levels of pollutants currently emitted by some of Risemia's manufacturing plants are not considered excessive.
The stockholders of most of Risemia's manufacturing corporations exert substantial pressure on the corporations to comply with environmental laws.
因：法规限制污染，制造业产品价格上涨导致出口市场的损失；
果：制造业产品的年出口量将会下降；
攻击方向：（1）攻击前提：无关因，即法规限制、出口市场损失和年出口量无关（这里似乎挺难攻击的）；（2）攻击结论：干扰因素使结论不成立，法规限制排污的高要求，激发企业研发国际领先的排污设备（此即为干扰因），而对于这个设备可能会出现a strong worldwide demand，那么年出口量则不一定会下降，削弱结论。
