Tax evasion forces lawmakers to raise income tax rates, whihc causes the tax burden on nonevading taxpayers ot become heavier. This, in turn, encourges even more taxpayers to evade income taxes by hiding taxable income.

题目是假设！

前提是 When people evade income taxes by not declaring taable income


结论为 Tax evasion forces lawmakers to raise income tax rates, whihc causes the tax burden on nonevading taxpayers ot become heavier. This, in turn, encourges even more taxpayers to evade income taxes by hiding taxable income.


演绎方向：前提结论形！

assumption 的思路 1、架桥   2、not weaken

weaken的思路只能是1、断桥  2、他因否认结论

答案为： When lawmakers establish income tax rates in order to generate a certain level of revenue, they do not allow adequently for revenue that will be lost through evasion.


为not  weaken
weaken 的解释为：
他们在制定税率的时候，已经考虑了由于偷税所造成的损失！
为断桥型削弱！
