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.
