问题 Kansas and Iowa, rich in wind resources, can provide more electricity than other states. [br]  
If that sounds ambitious, consider that the country has installed some 50, 000 wind turbines on land over the past two decades. They now supply roughly 5 percent of the nation’s electric power, a figure that reaches double digits in particularly windy states like Kansas and Iowa.
Home to 25% of the world’s oil reserves, the Eastern Province is the economic engine room of Saudi Arabia, accounting for more than half of the Kingdom’s oil production and about 7% of total global output.

选项 A、正确
B、错误

答案 B

解析 数字混淆,应该是世界石油储备的25%。
