好吧谢谢记下了。。。

弱弱地举手。。。和答案无关，只是我不明白题干中“做广告的律师比没做广告的律师收费低”是为神马啊为神马啊？

不要对题干直接给你的前提条件产生疑问（别用常识，什么打了广告应该更贵啊，别考虑它）。尤其体现在这类纯归纳题（注意：其他类题不一定适用啊！！！），直接用题干中的条件往后推（往后别往前），题干中没提的东西，答案中出现了---错，题目中从A到B的关系，答案中从B到A---也错。

This is a must-be-true question, meaning the answer choice has to be EXACTLY what has been said in the stimulus.

In fact, this is the easiest for logic question because the answer has been given (in the stimulus).

Premise:
1) fewer restrictions --> more lawyers advertise
2) lawyer who advertises --> charge less

Conlusion
remove restricion --> overall cost less for consumer

Then what has to be true :
remove restricion --> more lawyer will advertise, which is basically the first premise.

我的想法和你一样

3楼sdcar的解释很好。

另外，感觉这题中(D) If more lawyers advertise lower prices for specific services, some lawyers who do not advertise will also charge less than they currently charge for those services.其实是这题的assumption。
strengthen题中有premise和conclusion，暗含assumption。
inference题没有conclusion，或者说题中可能有可以理解为conclusion的东西，但是正确选项才是题目的conclusion。那些可能成为conclusion的东西只是它的premise。
C项实际是对题目第一句的复述。
D项不做广告的律师也会减少收费是assumption。因为题中结论：减少限制后，法律费用会降低。但是即使减少限制后会有更多律师做广告，做广告的律师收费会降低。但我们不知道继续不做广告的律师收费是否会提高。如果提高很多，那就可能总体的法律费还是会上升。D正是排除这种可能。
但这题问must be true，所以选C
