70. 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. 答案是 C 想請教 ABD 和 C 的不同之處, 是否在若 ABD 是真的, 此 vicious cycle 根本不會形成但題目已經說了有這樣一個惡性循環存在故 ABD 其實是在 "反駁題目", 所以不對而 C 正確的原因, 是此 vicious cycle 先存在然後再藉由 C 的成立而把此惡性循環破壞掉所以 ABD 是根本沒有 vicious cycle (反駁題目) 而 C 是把進行中的 vicious cycle 破壞掉不知道我的理解有沒有錯誤? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 118.168.68.146
