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.

-We should consider unrefined oil
B. The quality of an unrefined olive oil can be determined only by accurately
measuring its acidity.
- but there is some other method to do this, “is not actually defined in terms of 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.
- true if true, acidity defines quality
D. Free oleic acid is the only acid that unrefined olive oil contains.
- don’t know, may be true
E. People who judge the quality of unrefined olive oils actually judge those oils by
their acidity, which the judges can taste.
-People don’t judge in this way

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. -> irrelevant
B. The quality of an unrefined olive oil can be determined only by accurately measuring its acidity. -> nopes since nowhere in the argument its said we can get quality in terms of oleic acid concentration or acidity.ELIMINATE
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. -> this is perfect since relative data is established
D. Free oleic acid is the only acid that unrefined olive oil contains. -> irrelvant
E. People who judge the quality of unrefined olive oils actually judge those oils by their acidity, which the judges can taste.-> irrelevant


ACCEPTED FACT(1) : The quality of unrefined olive oil is not actually defined in terms of acidity

Experiment results : the less free oleic acid an unrefined olive oil contains per liter, the
higher its quality

ACCEPTED FACT(2) : The proportion of free oleic acid that an olive oil contains is an accurate measure of the oil’s acidity.

from the above we are sure that even if experiments are carried out a direct calculation of the quality of olive oil cannot be made knowing the % of oleic aid in olive oil.Only relative study and data can be obtained when two three samples are tested .
Hence I go for C

I hope this is the answer :)
