求NN帮忙解释紫皮OG70题-之前帖子解释寥寥无几

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 vareis 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

OG 解释怎么也看不懂..其实这道题目我就有点不理解..C选项的“they do not allow adequately for revenue that will be lost through evasion”作何理解呢?

OG说when considering income tax rates in the first place, lawmakers must not take into account the amount of revenue that will inevitably be lost to evasion,不懂...

Assumption题。

C: 在为了实现一定税收收入的时候，lawmaker不会把某些人通过避税带来的损失计算在内。

取非：在为了实现一定税收收入的时候，lawmaker会把某些人通过避税带来的损失计算在内。如果这样，lawmaker就不用提高税率了。

PS: Allow...for...

If you allow a particular length of time or a particular amount of something for a particular purpose, you include it in your planning.
