PREP-1-56 中的一句话...

56.   (34605-!-item-!-188;#058&007579)

Crops can be traded on the futures market before they are harvested.  If a poor corn harvest is predicted, prices of corn futures rise; if a bountiful corn harvest is predicted, prices of corn futures fall.  This morning meteorologists are predicting much-needed rain for the corn-growing region starting tomorrow.  Therefore, since adequate moisture is essential for the current crop's survival, prices of corn futures will fall sharply today.

Which of the following, if true, most weakens the argument above?

(A) Corn that does not receive adequate moisture during its critical pollination stage will not produce a bountiful harvest.

(B) Futures prices for corn have been fluctuating more dramatically this season than last season.

(C) The rain that meteorologists predicted for tomorrow is expected to extend well beyond the corn-growing region.

(D) Agriculture experts announced today that a disease that has devastated some of the corn crop will spread widely before the end of the growing season.

(E) Most people who trade in corn futures rarely take physical possession of the corn they trade.

  这句（红字的）是范围超过了CORN生长的面积（CORN已经在里面了）

  还是CORN不在雨水到达的面积里？？？？？

The rain that meteorologists predicted for tomorrow is expected to extend well beyond the corn-growing region.

意思是雨水将会滋润比corn-growing region更广的区域，这是一个区域的包含关系，也就是为了强调整个corn-growing region都会被雨水滋润到。是明显的加强选项

I don't understand.

In OG 11th, the answer is C

Ｃ项非常的靠近题目，雨水，气象，玉米的收成情况．

我想Ｃ的翻译应该是，雨水超过了corn-growing的生长需求的region.即，雨水过多，对ＣＯＲＮ生长不利．

超出这个想法不成立的，文章已经告诉我们水师有益与玉米生长的
