#122) 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?
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.
题干Vicious cycle: ppl evade taxable income------>(????)-------->lawmaker raise income tax rates------->tax burden on nonevading taxpayers to become heavier----->encourages even more taxpayers to evade income taxes ------->law....
问题The vicious cycle described above could not result unless which of the following were true? 逆否一下If the statement of the following were ture, then the vicious cycle described above will result. (既找假设)
就像Midfree大大说的那样 假设是连接reasioning line的一部分 而缺口就在reasioning line开始部分 为什么人们逃税就会-----导致------>lawmaker提高rates? 因为假设(即C中)lawmaker对revenue的确定是有一定要求的 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. lawmakers -----> certain level of revenue------>not allow evasion 所以 当ppl evade taxable income(也就是Vicious第一个条件开始成立的时候) lawmakers才会 raise income tax rates------->tax burden on nonevading taxpayers to become heavier----->encourages even more taxpayers to evade income taxes ------->law.... 这个恶性循环才会形成
兄弟,你的逆否命题的推论有问题。The vicious cycle described above could not result unless which of the following were true并不等价于If the statement of the following were ture, then the vicious cycle described above will result.逆否命题并非单纯的顺序交换,而是因果关系的交换,你的这个推论,因果关系并没有变。你的转换就是A-B=非A-非B,这不是你否命题。
The vicious cycle described above could not result unless which of the following were true. ===> The vicious cycle described above could not result if which of the following were not true. ===> IF The vicious cycle described could reasult, Which of the following were true. 这回对了:]
