OK here is one Veritas Prep CR Question.
Acid rain, caused by high levels of sulfur dioxide and mercury trapped in global air currents, affects one third of China’s territory.Coal-fired power plants are notorious for emitting large quantities of these pollutants.To combat the problem, the Chinese national government has set aggressive environmental goals for the next five years.These goals include a 20-percent improvement in energy efficiency and a pledge that, by the end of the five years, 10 percent of the nation’s energy will come from renewable resources such as hydroelectric or wind power.
Which of the following, if true, is the best criticism of the Chinese government’s strategy as a method for achieving a reduction in acid rain?
(A) Some forms of air pollution, such as heavy particulate fumes, would not be affected by the suggested energy improvements.
(B) Once the changes have been implemented, the actual reduction in acid rain would vary from region to region.
(C) The goals would be forced on every region in China, including those that have no problems with acid rain.
(D) Acid rain is also caused by other factors, such as volcanic eruptions or pollution from neighboring countries, over which China has no control.
(E) Regional Chinese officials tend to ignore environmental regulations in order to meet aggressive economic requirements imposed on their regions’ industries.
According to Veritas, the correct answer is (E).My reasoning was that if acid rain is caused by other factors over which China has no control, even if the official were serious about environmental issues, the plan still wouldn't work. (Answer choice D)
Further explanation.
This is how i saw the questions. The Chinese Govt wants to a) "combat the problem" by b) Setting up aggressive environmental goals.
Will implementing (b) necessarily reduce acid rain ?
I have to assume that these goals will necessarily lead to the reduction of acid rain. But why should i assume that ? Answer choice D clearly creates an opening for weakening this by challenging this assumption. What if the plan is inherently flawed and the implementation is not an issue at all.
How can i assume that the Chinese govt has taken all the factors into consideration except one i.e. officials don't take environmental issues seriously. What if they completely overlooked the fact that other factors over which they have no control cause acid rain.
So now why is Answer choice E correct and not answer choice D ?
