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. eople who judge the quality of unrefined olive oils actually judge those oils by their acidity, which the judges can taste.作者: Chrislvzh 时间: 2011-3-20 00:16

This an inference question, which means the correct answer must be true.
The conclusion you can draw from the stimulus is that the level of acidity in unrefined olive oil is a working measure of the quality of the oil.
Therefore, C must be true since it compares the quality of unrefined ollive oils by comparing the acidity thereof.作者: Uya 时间: 2011-3-20 11:30
