Contrary to earlier predictions, demand for sugarcane has not increased in recent years. Yet, even though prices and production amounts have also been stable during the last three years, sugarcane growers last year increased their profit by more than 10 percent over the previous year's level. Any of the following statements, if true about last year, helps to explain the rise in profits EXCEPT:
Many countries that are large consumers of sugarcane increased their production of sugarcane-based ethanol, yet their overall consumption of sugarcane decreased.
Sugarcane growers have saved money on wages by switching from paying laborers an hourly wage to paying them by the amount harvested.
The price of oil,the major energy source used by sugarcane growers in harvesting their crops, dropped by over 20 percent.
Many small sugarcane growers joined together to form an association of sugarcane producers and began to buy supplies at low group rates.
Rainfall in sugarcane-growing regions was higher than it had been during the previous year, allowing the growers to save money on expensive artificial irrigation.
需求没有增加。但是sugarcane的价格和总量在之前的三年中一直很稳定，跟去年相比，整体的收益提升了10%。 问题：以下哪种情況不能解释去年的现象？ A，甘蔗消費大户提高了甘蔗造酒的量，但是总体对甘蔗的消费降低了。解释不了任何问题，无关。 B，甘蔗种植户节省了劳动工资——降低成本，因此利润提高 C，甘蔗种植相关的油价下降了20%——降低成本，因此利润提高 D，甘蔗种植户結成联盟，团购设备——降低成本，因此利润提高 E，下雨多，节约了灌溉的費用——降低成本，因此利润提高
