题目选项分析

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?

【选项】The Malbec vine is susceptible to phylloxera, a plant louse that only grows at low altitudes.

选项是否正确?
