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?

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.

B) The proposed regulations include a schedule of fines for noncompliance that escalate steeply in cases of repeated noncompliance.

C) Savings from utilizing the chemicals captured by the pollution control equipment will remain far below the cost of maintaining the equipment.

答案是A,没有问题.请问C是什么意思,为什么是加强

C says, if they use those equipment to capture the chemicals, the chemicals

they get can provide them some savings. But these savings will be much less

than the equipment maintenance cost. Thus, conclusion will be: it's not

worth using these equipment - Strengthen
