If motorization continues to expand, it is expected to significantly increase air pollution levels and cause substantial hazards to residents in highly populated areas. An initiative was taken to reform the sales tax, so that tax brackets will be determined according to the emission levels of vehicles. By providing an incentive to purchase smaller cars, the pollution rate will deteriorate.
Which of the following assumptions is crucial for the success of the new tax reform?
A. Citizens are expected to purchase fewer cars, thus lowering the motorization level.
B. Implementation of the new sales tax will result in increased use of public transportation instead of privately own cars.
C. The reformed sales tax will not cause polluting car manufacturers to deliberately alter the emission levels in their reports to the tax authorities.
D. Most people consider air pollution an important environmental issue that should be addressed by the authorities.
E. Vehicles with polluting engines could be sold to countries with lower motorization levels.
Official Explanation:
We’ll look for an answer that tells us something that is crucial to the reform’s success in lowering air pollution.
(A) and (B) aren’t crucial assumptions – the argument demands that people purchase smaller cars, not that they drive less in private cars altogether.
(C) is a crucial assumption – if manufacturers alter the emission levels, the whole reform will miss its goal altogether. (D) isn’t really relevant – the plan is to give people an economic reason to pollute less, regardless of what they think of environmental issues.
(E) isn’t directly relevant to the success of the reform in the places where it is implemented.
