GMAT Critical Reasoning
Prolonged spells of hot, dry weather at the end of the grape-growing season typically reduce a vineyard's yield, because the grapes stay relatively small. In years with such weather, wine producers can make only a relatively small quantity of wine from a given area of vineyards. Nonetheless, in regions where wine producers generally grow their own grapes, analysts typically expect a long, hot, dry spell late in the growing season to result in increased revenues for local wine producers.
Which of the following, if true, does most to justify the analysts' expectation?
- A The lower a vineyard's yield, the less labor is required to harvest the grapes.
- B Long, hot, dry spells at the beginning of the grape-growing season are rare, but they can have a devastating effect on a vineyard's yield.
- C Grapes grown for wine production are typically made into wine at or near the vineyard in which they were grown.
- D When hot, dry spells are followed by heavy rains, the rains frequently destroy grape crops.
- E Grapes that have matured in hot, dry weather make significantly better wine than ordinary grapes.
Correct Answer: E
