不是最终答案是lawyer讲的A了么

GWD-10-Q30:GWD-2-17

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.

我还是同意A。因为C不能从文中推出的。

acidity of oil不是评价oil quality的标准，所以我们不知道intermediate in acidity是否能证明quality也是中间。所以C是非常没有根据的。

A是对的。free oleic acid 和oil quality成正比。A说了，如果oil 给refine了，oleic acid就少。把两句话合在一起，我们推出，如果oil refine了，oil qulity就高。这个的确没有在原文中说过refined oil，但是我们不要太钻牛角尖，难道提纯的oil质量还比unrefine的oil质量差了？这个不需要原文提供，常识就知道，refine这个词也说明了quality的提高。

如果对于refine的正确意义没有问题的话，那A正好是原文能推出来的结论。

完全同意12楼的

查了refine的意思，觉得refine正好对应了题目中的“less free oleic acid"

即使A是对的，上面的推理也是不正确的

原文：

(1)  A of UO  不能 --> Q of UO

(2) FOA of UO↓ --> Q of UO↑

(3) FOA of O --> A of O  （注意不是FOA of O <---> A of O）

我觉得A、C都有问题：

A：文章只提到FOA，没有提OA，因此A的结论不能must be true（必须加入其他没有出现的信息才能推出A）；lawyer的说法必须基于一点：最后一句中的an olive oil＝refined olive oil。

C：从2、3可以看出原文一直在说FOA决定Q、FOA决定A，无法推出A决定Q，所以C不对

那如mm所说，只要extensive tests have shown that the less free oleic acid an unrefined olive oil contains per liter，the higher its quality. 这一个前提就够了， 别的全是废话。 因为精炼橄榄油可以看成原榨橄榄油的提升版，条件可以看成extensive tests have shown that the less free oleic acid  olive oil contains per liter，the higher its quality.细节决定成败啊。 呵呵呵 前提都得用上哦 除非前提被否定。

acidity of oil不是评价oil quality的标准，所以我们不知道intermediate in acidity是否能证明quality也是中间。所以C是非常没有根据的。

=>可是題干中有提到"the less free oleic acid an unrefined olive contains per liter, the higher its quality". 這樣不就可以知道品質和酸度的關係嗎? 所以在C中提到an unrefined olive oil的酸度介於其他unrefined olive oil中間, 則品質也是介於中間...聽起來也合理耶....

A是对的。free oleic acid 和oil quality成正比。A说了，如果oil 给refine了，oleic acid就少。把两句话合在一起，我们推出，如果oil refine了，oil qulity就高。这个的确没有在原文中说过refined oil，但是我们不要太钻牛角尖，难道提纯的oil质量还比unrefine的oil质量差了？这个不需要原文提供，常识就知道，refine这个词也说明了quality的提高。

=>我一開始也是選A, 可是我後來發現A有問題, 因為題干並沒有提到經過refine程序的olive oil, 它的酸度會減低. 有可能refine的程序不佳, 酸度還是不變. 誰知道refine的程序是啥呢? 有可能是指去除雜質的refine....(只是舉例, 沒有鑽牛角尖..)

如果对于refine的正确意义没有问题的话，那A正好是原文能推出来的结论。

所以結論是答案選C

歡迎討論哦~

常识如果这么用，那还要原文干吗？

原文里说在unfefined的oil里，free oleic acid 和 oil quality成正比，一点没提到在refined oil里oleic acid 和quality是什么关系，或许refined oil，其quality的评判标准和 crude oil完全不一样了呢？
