The Malbec grape, originally grown in France, has become the main varietal in Argentina. This is surprising because most Malbec grown in Argentina is grown at high altitudes, whereas the Malbec grape once was grown at low altitudes. Therefore, Argentinian winegrowers should grow the Malbec grape at low elevations.

Which of the following, if true, would most weaken the conclusion of the argument?

A) The Bordeaux grape is the most popular grape in France but is rarely, if ever, grown in Argentina.
B) Some varietals are unable to grow at high altitudes.
C) The soil at high altitudes is filled with nutrients that help many of Argentina’s varietals flourish.
D) The Malbec vine is susceptible to phylloxera, a plant louse that only grows at low altitudes.
E) Malbec has recently enjoyed a surge in popularity, and can be found in many different countries.

Can you explain why "D" is the correct answer? We don't know whether phylloxera is even present in Argentina. The question does tell us in "C" that the plants grow better at high altitudes in Argentina because of the nutrient rich soil. Therefore, why would the Argentine follow the French tradition of growing the Malbec grape at low altitudes when they can get better yields by growing it at a high altitude in their country?

Hello jhabib

I agree this is a tricky one and first time I was not agree with answer.

Answer C says that "The soil at high altitudes is filled with nutrients that help many of Argentina’s varietals flourish."
But how this fact connected to Malbec grape?

D is not the best answer but this is peculiarity of weaken questions: correct answer is not obligate to be the best variant and completely destroy the conclusion of argument. It can just a little weaken it.
And answer D do so: it not destroy the argument but create a circumstance why Malbec grape should be grown on high altitudes of Argentina.

Official Explanation
Answer: (D)

The Malbec grape was originally grown at low altitudes in France. The conclusion: Growing the Malbec grape at low altitudes in Argentina is a good idea. The correct answer will suggest that growing Malbec grapes at low elevations is a bad idea.

(D) provides a good reason not to grow Malbec grapes at low elevations. There is a louse that can hurt the grapes (it's not specified where this louse lives, so we must assume that it could possibly live in Argentina). It only lives at low elevations; therefore, growing Malbec grapes at low elevations might be a bad idea.

(A) is irrelevant.

(B) is too vague because it doesn’t relate specifically to Malbec grapes.

(C) is very tempting. Notice that ‘Argentinian varietals’ doesn’t necessarily include Malbec grapes. Secondly, the nutrients at high elevations could be at low elevations. That there are nutrients in the soil at high elevations doesn’t automatically mean, at least, that growing Malbec grapes at low elevations is a bad idea.

(E) is just a generic fact about Malbec grapes and does not relate to the argument.
