第10题：
The actively July contract for soybeans rose 20 cents to settle at $14.85 a bushel.
The U.S. government's weekly prediction for soybean exports was higher than traders expected, said Mike Zulo. President of a consulting company in Atchison, Kansas.
Supplies for beans have been extraordinarily tight as China's demand for soymeal continues to increase even as U.S. production stays relatively steady, he said. Soybean prices have risen about 15 percent this year.
“That U.S.D.A. number caused the trade to refocus on just how razor-thin supplies are heading in to next fall's harvest.” Zulo said.
Why did the prices of soybean rise according to the passage?
B.Because the supplies were expected to keep tight.
C.Because China’s demand for soybean increased.
D.Because the trade of soybean was quite active.
【关键词】why；prices of soybean rise
