If the quality of the blended whisky derives from the quality of its component ingredients, then MacDuff's whisky must be the finest whisky in the world, because it blends no fewer than five Scotland's finest single-malt whiskies.

The argument above could be seriously weaken if which of the followin were true?

A. The more single-malt whiskies involved in the batch of blended whisky, the finer the quality of whisky.

B. Whereas many of MacDuff's competitors have been in industry for decades or even century, the MacDuff brand was created within the last decade by marketing committee.

C. Including more than five single-malt whiskies in a blended whisky is a waste, because no one can taste that many component flavors.

D. A blended whisky is as fine as the average quality of its components.

E. The concept of "finest" in a whisky is a subjective measure that cannot be quantified in a statistically valid way.

I did not get this question.

Can somebody explain the why the credited answer is correct?

simple :

You are mixing 5 components with rating : 4 5 6 7 8 -to make new component A

So avg rating = 6

D says : rating of the new component A = avg rating = 6

clearly 6 < 10, so it is not the best.

Hey Thanks Man!!!
Awesome is your maths!!! I got the clue from ur explanation

Actually, the argument says that quality of a blend is proportional to that of its components.

D denies this, saying that such proportionality does not exists.
Rather
quality of a blend is linked to the AVERAGE of the qualities of its components.
