Why would the farmers leave the fields empty even though conditions suggest it would be profitable to plant soybeans? The farmers were not able to plant corn this year. Consequently, why would they not make up for it by
planting soybeans? Soybean prices are especially high, so it would presumably be profitable to plant them. Why would the farmers leave the fields empty instead? Look for an answer option suggesting why it would be unprofitable or unfeasible for them to take advantage of the conditions favoring soybean planting.
A. Corn planting season is over, and therefore the farmers could not plant corn to profit from the high corn prices-and even if they could, it would not explain why they are leaving the fields empty.
B. This does not explain why the farmers are not planting soybeans. If the farmers anticipate serious financial losses, that would be all the more reason for them to try to recover financially by planting soybeans.
C. Correct. This gives a good reason for not planting soybeans. It might not be profitable to do so.
D. The passage is about the farmers who could not plant corn, not about those who could.
E. If the farmers are accustomed to planting soybeans, it would probably be even easier and more profitable for them to do so this year rather than leaving the fields empty.
The correct answer is C.
