GWD-2-Q17

    

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?

    

 

    

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

    

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

    

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

    

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

    

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

这个题应该选什么啊？觉得好像没有答案？我理解题目的意思是，仅仅看acidity不够，需要看 free oleic acid的量……可能是理解错了？请高人指点！
