Crops can be traded on the futures market before they are [#permalink]  01 Jan 2013, 12:29

Question Stats:

81% (01:42) correct 18% (01:22) wrong based on 2 sessions
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.

I shortlisted choice C and D. Correct Answer D

Now Lets Play.
Poor corn = price rise
Bountiful corn = Price fall
Effect of News = corn crop will flourish
Conclusion = Price will fall today
scenario that might weaken the conclusion = their must another news to come which would tell that crops are not gonna flourish despite rain.
Choice D = crop will not flourish despite rain.
Choice C = crop will not flourish because of lack of rain.

I want to know Is Choice C wrong because it is refuting the premise? or there any other reason behind it.

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. is irrilevant the pollination
(B) Futures prices for corn have been fluctuating more dramatically this season than last season. the comparison betwee this season and the last is not importnat for the argument at stake
(C) The rain that meteorologists predicted for tomorrow is expected to extend well beyond the corn-growing region. the fact that the rain will expand farther is not relevant
(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. this is a reason out od scope that weaken the argument
(E)Most people who trade in corn futures rarely take physical possession of the corn they trade. future trade is irrilevant

hope is clear
