但我google 了一下，有个GMAT CLUB里的人下定义说：（以下是基于逻辑Boldface练习题-01的解释） Principle(principle is much stronger such as Buoyancy/Gravity etc can be applied widely) Evidence - evidence has to support the conclusion directly (ref: http://gmatclub.com/forum/cr-navigation-75974.html)
这样的话，我们好多理解都不正确。 我在google上面看到逻辑Boldface练习题-01选C，但我们选E。他们给出的解释用的是排除法。原因就是Principle是大家都要认可的一般规律。如万有引力等 Cite from (http://www.beatthegmat.com/bold-face-modern-navigation-systems-t18117.html)
我又想起我们每次看书的时候关于定理，我们都用Principle1，principle2.。。
还在：“boldface中的一些基本概念 ”里面发现了解释： ”Principle: something fundamental that we do not question. This would be somewhat stronger than a fact because it is not specific to a limited number of cases but instead, apply to a broader range of scenarios(and often deeper in meaning). For instance, you will not talk about the principle that crime is increasing in large cities. Instead, it is a fact which applies to large cities. However, you will talk about the principles of Physics or the fundamental principles of Human Rights. I believe principles convey a stronger connotation than mere facts.“ http://forum.chasedream.com/GMAT_CR/thread-164744-1-1.html 所以我觉得principle应该是个公认的定理。比FACT更有逻辑性，广泛性和适用性。
请问： 1. principle是不是应该被理解成由fact直接归纳出来的广为人知的定理？ 2. Boldface练习题-01到底应该选什么（这个问题base on the definition of “PRINCIPLE")
PS:第九题我选A，reasons same with below: 1) Second part is not inference but a conclusion. 2) First part is not evidence, but background over which argument is built on. http://tianlong-gmat.blogspot.com/2006_03_01_archive.html

那你说什么是定理，什么是原理，两者主要区别在哪里呢？
