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?
69. 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 non-evading 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.
LS 谢谢你的回答 但是我觉得你的逻辑貌似不太对诶 1. 题目问的是“The vicious cycle described above could not result unless which of the following were true?”……就是问哪一个选项能停止这个恶性循环 2. 你说的那个“A1、A2”模型好像也怪怪的,为什么“when A2 covers A1, the cycle stops!”呢?依然会继续恶性循环吧…… 3. 我查了下,allow for是指“考虑到,估计到”,allow adequately for应该是“充分考虑到”
还是用数学的方式想吧,THIS VICIOUS CIRCLE IS BETWEEN: TAX EVASION---LAW---TAX EVASION SO, THE ANSWER MUST CONTAINS THE 2 FACTS.. ONLY B&C HAVE THE 2 FACTS B IS NOT SUPPORTING SO, CHOSE C
