这道题我支持Ｃ

理由如下：这道题目是支持结论型的，只要选直接支持结论那一项即可．

题目的结论是：The quality of unrefined olive oil is not actually defined in terms of acidity, yet extensive tests have shown that the less free oleic acid an unrefined olive oil contains per liter, the higher its quality.

就是说unrefined olive oil的质量不能很精确的通过acidity来定义，然而大量的实验证明the less free oleic acid an unrefined olive oil contains , the higher its quality.

我对这句话的理解为，acidity不可以很精确的实在的衡量the quality of unrefined olive oil但是可以大概的衡量．那么Ｃ选项说的就很正确了．

 If an unrefined olive oil is intermediate in acidity between two other unrefined olive oils, it will also be intermediate between them in quality.

直接就是支持结论的，不是说质量直接跟acidity的关系，而是说了一个大概的，在什么和什么之间．

 If an unrefined olive oil is intermediate in acidity between two other unrefined olive oils, it will also be intermediate between them in quality.

到底要选什么啊`````!?  彻底晕了`````

不能这样把acidity和quality挂钩

我认为各位都想复杂了，正中了ETS圈套，其实这题该选D：Free oleic acid is the only acid that unrefined olive oil contains.

理由：从最后一句The proportion of free oleic acid that an olive oil contains is an accurate measure of the oil’s acidity.就可以得出（用美国人的简单思维）

既然FREE这个东西一个参数就能准确决定油的酸度，那么一定不含其他的酸性物质

C不对：文中虽然中间一句（1）the less free oleic acid an unrefined olive oil contains per liter, the higher its quality；（2）最后一句推出less free oleic acid--->higher acidity,但是文中第一句明确说了即使酸度与质量成正比，但是不能用酸度来判断质量

即（2）less free oleic acid--->less acidity

（1）less free oleic acid--->higher quality

不能推出less acidity--->higher quality(如果没有第一句这个断桥，就可以从上面2个等式推出C的关系（当然，推理的过程是我们平常通用的AB正比，BC反比，所以AC反比的思维；但是有了这个断桥，即使我们推出来了，也要被第一句给否定）ETS就是借助了这个常用思维来误导了我们^-^)

那么23楼就是错误的，即便是一个在中间的数，也是依靠正比关系得出的一个模糊关系，而依照我的分析，得不出正比关系的，而且not actual的意思是很明确的否定(与事实相反)，不是你理解的“不准确的意思”

原来错选了A，现在坚决同意C

原文用yet后面的内容清楚说明了由acid含量与质量好坏的关系，可以推出C

而A是无关，因为原文通篇在讲unrefined，不能简单推理出refined的情况

The quality of unrefined olive oil
            is not actually defined in terms of acidity, yet extensive tests have shown that the less free oleic acid an unrefined
            olive oil contains per liter, the higher its quality.  The proportion of free oleic acid that an olive oil contains is an accurate measure of the oil’s acidity.

我的疑问是红色处的oil 是unrefined 还是 refined??? 如果是refined考虑A选项时就不能把它定义为out  of scope 了...
