The proportion of free oleic acid that an olive oil contains is an accurate measure of the oil’s acidity. 未提炼的橄榄油的质量与酸度无关。 油酸越少橄榄油质量越高 油酸是油的酸度的准确衡量。 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.
