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.

Answer B and D seems extreme. Answer E seems out side of the scope. I am between A and C. I think I am going to chose C because the statement mentioned about unrefined oil not refined as mentioned in A.

So, C for me.

1) - quality of olive oil inversely proportional to free oleic acid

The proportion of free oleic acid that an olive oil contains is an accurate measure of the oil’s acidity.

2) - acidity directly proportional to proportion of free oleic acid

If the statements above are all true, which of the following conclusions is best supported by them?

From 1 and 2 therefore, Higher oleic acid ---> lower quality. So, if intermediate oleic acid --> intermediate quality.

Concur with C

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

I say C for this.

A: We are talking about unrefined olive oil.
B: argument says that other methods are used.
D: Maybe, but we can't determine this from the passage.
E: Goes against passage.

My problem with this is that C directly contradicts the first statement.

"the quality of unrefined olive oil is not actually defined in terms of acidity..."
Answer choice (C) says
"If an unrefined olive oil is intermediate in acidity between two other unrefined olive oils, it will also be intermediate between them in quality."
Which translates to intermediate in quality = intermediate in acidity
so quality = acidity
which contradicts the first part of stem.

Can someone help me understand this? Was this an official GMAT question?

The acidity may INDICATE the quality, but it is not used to DEFINE the quality.

For example: Mass number of an atom is DEFINED as the total number of protons and neutrons in an atom. Higher the mass no., higher is the mass of the atom. Nonetheless mass is not used to DEFINE mass no. of an atom,but just an indication of the mass no.

Here,
mass no. is equivalent to quality
mass is equivalent to acidity
no. of protons and neutrons is equivalent to some parameter that has not been specified in the passage -a parameter used to DEFINE the quality.
