唔...又是我 不好意思.. 这题选E没意义,原文提及通过同义替换,故选 但有两个选项不明白... 此题第3个选项:It overestimates the amount of commercial activity that is generated in the United States不可么? 我觉得就是过分估计了 类似oil spill这种东东generates commercial activity,
那第2个选项:It is based on inaccurate estimations of the prices of many goods and services 我能不能看作是因为选项中是price,而文中所说的是没有正确考虑goods and services的value, 所以错?
