以前没讨论过 gwd-1-30 C vs E

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 ?

1. When an olive oil is refined, the concentration of oleic acid in the oil is reduced.

2. The quality of an unrefined olive oil can be determined only by accurately measuring its acidity.

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

4. Free oleic acid is the only acid that unrefined olive oil contains.

5. People who judge the quality of unrefined olive oils actually judge those oils by their acidity, which the judges can taste.

我能理解答案为什么是C,只是我有点疑惑E是否错在：which the judges can taste,是属于文中没提供的信息。望牛人不吝指点！

有争议，个人还是站在lawyer一边，A

E错。一是Taste原文根本就没这方面的信息，二是原文已经说了The quality of unrefined olive oil is not actually defined in terms of acidity，并且其他人怎么判断这个质量，从原文也无法推出。

谢谢fogwind，小妹明白了
