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.

The conclusion of the argument states -- "The proportion of free oleic acid that an olive oil contains is an accurate measure of the oil’s acidity" i.e we can easily state that "Free oleic acid is the only acid that unrefined olive oil contains" i.e option 'D'.

Can anyone please elaborate as to why 'D' is wrong here.

Just because it is extreme ?

I have the same problem, I don't understand why D is wrong.. " accurate" means exact, so only the Free Oleic Acid is present in the unfiltered olive oil

A. When an olive oil is refined, the concentration of oleic acid in the oil is reduced. -> irrelevant as passage is about unrefined olive oil only
B. The quality of an unrefined olive oil can be determined only by accurately measuring its acidity. -> This is an extreme.
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. -> Correct
D. Free oleic acid is the only acid that unrefined olive oil contains. -> extreme
E. People who judge the quality of unrefined olive oils actually judge those oils by their acidity, which the judges can taste. -> irrelevant

Hi,
Can you tell me why choice D is wrong in this CR question. It is obvious from the last sentence that the measure of oleic acid is the only measure of acidity. This is directly stated in choice D. I think, to reject an option just because it is extreme can't be an intelligent method to solve CR Qs.

First, the last sentence does not say that the measure of oleic acid is the ONLY measure of acidity. Instead, the last sentence tells us that it is AN accurate measure of acidity. There could be numerous other measures of acidity.

Second, just because the proportion of free oleic acid is an accurate measure of an olive oil’s acidity does not mean that free oleic acid is the ONLY acid in unrefined olive oil. Unrefined olive oil could contain numerous other acids, and that would not contradict anything in the passage.

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

Because of the word "only", choice (D) must be eliminated.
