求解释，新版 prep 逻辑的 Q 50 Assumption 题

When people evade income taxes by not declaring taxable income, a vicious cycle results.  Tax evasion forces lawmakers to raise income tax rates, which causes the tax burden on nonevading taxpayers to become heavier.  This, in turn, encourages even more taxpayers to evade income taxes by hiding taxable income.


The vicious cycle described above could not result unless which of the following were true?


(A) An increase in tax rates tends to function as an incentive for taxpayers to try to increase their pretax incomes.
(B) Some methods for detecting tax evaders, and thus recovering some tax revenue lost through evasion, bring in more than they cost, but their success rate varies from year to year.
(C) When lawmakers establish income tax rates in order to generate a certain level of revenue, they do not allow adequately for revenue that will be lost through evasion.
(D) No one who routinely hides some taxable income can be induced by a lowering of tax rates to stop hiding such income unless fines for evaders are raised at the same time.
(E) Taxpayers do not differ from each other with respect to the rate of taxation that will cause them to evade taxes.


不明白为什么选C呢，

这道题目的逻辑我认为是有人逃税所以政府加税率然后逃税的人更多了
C选项关键在于allow的理解 allow作为非及物动词有考虑的意思 我觉得这里的allow是考虑的意思
所以 C的意思就变成政府在制定政策的时候没有考虑到tax evasion
根据laywer大帝的理论 这个属于assumption题中假设其他方面没有影响的题

换种说法 假设政府制定政策的时候考虑到了未来会有更多的tax evasion 税率就会根据这个预期做调整
