lz逻辑一直是最薄弱的，但也经过了大量的练习与总结能分析每一道逻辑题是什么套路，也知道选项大致的方向，但常常卡在比较tricky的无关选项的排除上。lz之前以为无关选项就是对结论没有影响，但有些无关选项做题的时候会觉得明明这个能影响到结论呀~为什么答案上说无关呢？
就好比这道题的E选项，好像是也跟结论有一丢丢相关的，吧，但解释中说是irrelevant...
Congress has passed a law that scales back the tax credits offered to purchasers of hybrid cars. Because of this, the number of hybrid cars sold each year, which has approximately doubled in each of the last five years, is likely to flatten in the next few years.
Which of the following statements, if true, most weakens the conclusion that the number of hybrid cars sold annually is likely to flatten in the next few years?
- AMost people buy hybrid cars for reasons other than to save money in the long run. 分析该选项
- BRecently published studies have shown that hybrid cars cost significantly more to repair and maintain than do comparable traditional cars. 分析该选项
- CGasoline prices are projected to fall over the next few years. 分析该选项
- DHybrid vehicles have a reputation for having less power than comparable non-hybrid vehicles. 分析该选项
- EManufacturers have significantly increased their budgets for advertisements touting the fuel efficiency of hybrid cars.
然后又经过我自己的一些总结，好像跟讨论对象/限定范围/直接前提无关（除了他因削弱）但对结论有影响的也都属于无关选项？
希望有NN评价一下我的这个“猜测”或者能阐明一下到底何为无关~~~
