[求助]AA77思路

77.

The following appeared in a letter to the editor of a popular science and technology magazine.

“It is a popular myth that consumers are really benefiting from advances in agricultural technology. Granted — consumers are, on the average, spending a decreasing proportion of their income on food. But consider that the demand for food does not rise in proportion with real income.
                As real income rises, therefore, consumers can be expected to spend a decreasing proportion of their income on food.
                Yet agricultural technology is credited with having made our lives better.”

结论是什么?还有5天考试, 还要上班. 晕

hehe, 这题超难的。

AA中，通常的结论是个立论，作者通过某些例子来论证自己的一个观点。不过这里是个驳论，作者否定了一个观点，"consumers are really benefiting from advances in agricultural technology."

注意，我们需要做的，是指出作者的推理得不出其结论，而不要画蛇添足去证明这个观点成立。

另外，myth的意思是神话，但是在GMAT里面通常的意思是误解，尤其是在阅读里面。
