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
题目分析：A说corn没有得到足够的moisture，原文问绕哪种corp谈的？是得到了足够的moisture谈的，范围驴唇不对马嘴，杀。B说corn的价格这个季度会比上个季度浮动的更厉害，没说，杀。C说下雨的范围会延伸，没说D说有病毒会影响crop，不就是除了原文天气影响之外还有别的影响嘛，可以驳斥，留着。E大多数人交易corp时候不会处理要交易的crop，没说，杀。
