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.
If the statements above are all true, which of the following conclusions is best supported by them?
When an olive oil is refined, the concentration of oleic acid in the oil is reduced
The quality of an unrefined olive oil can be determined only by accurately measuring its acidity.
If an unrefined olive oil is intermediate in acidity between two other unrefined olive oils, it will also be intermediate between them in quality.
Free oleic acid is the only acid that unrefined olive oil contains
People who judge the quality of unrefined olive oils actually judge those oils by their acidity, which the judges can taste
如果一种未精制的橄榄油在两种其他未精制的橄榄油之间的酸度中间，则它们之间的质量也是中间的。
为什么后来结论是 quality of unrefined olive oil can be measured in term of acidity.
难道是is not actually defined 不等于 can not be defined?
因为后面又一个yet让步吧，以后的讨论都朝着让步句中的方向去了
If an unrefined olive oil is intermediate （在。。中间）in acidity between two other unrefined olive oils, it will also be intermediate between them in quality.如果一种未精制的橄榄油在两种其他未精制的橄榄油之间的酸度中间，则它们之间的质量也是中间的。

define得出的（个人觉得应该)是指一个具体的数值或标准。比如说白酒的qualtity不能由酒精浓度来定义因为所采用的工艺和原料等都会影响的白酒的quality，如果我们要给这瓶白酒打分，可以是因为酒的工艺好原料好却因为酒精浓度不高，我们只给它75分。可是这只对是某一瓶白酒quality的评价，而我们通常都会说酒精浓度越高越纯的白酒，质量更好的，这才涉及到了不同的白酒间的简单比较。
