Yet, even though prices and production amounts have also been stable during the last three years, sugarcane growers last year increased their profits by more than ten 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: (A) Many countries that are large consumers of sugarcane increased their production of sugarcane-based ethanol, yet their overall consumption of sugarcane decreased. (B) Sugarcane growers have saved money on wages by switching from paying laborers an hourly wage to paying them by the amount harvested. (C) The price of oil, the major energy source used by sugarcane growers in harvesting their crops, dropped by over twenty percent. (D) Many small sugarcane growers joined together to form an association of sugarcane producers and began to buy supplies at low group rates. (E) 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.
Key：A 我选的是B。 1。想不通A为什么对，原文根本没提到用甘蔗做乙醇会跟profit有什么关系。 2。想不通B为什么不对，B当中已经提到因为wage的关系已经——HAVE SAVED MONEY，这么明显的已经saved money了，为什么就不能成为rise in profit的解释，难道节约成本跟提高利润没关系吗？
