题目的论点是 This fact does not show that environmental regulations promote growth, however, 要填 since 后面的内容,可以看成是对这个论点的加强题,或者是对 environmental regulations promote growth 的削弱。 A,给出他因,直接削弱。所以是正确答案 C,经济增长放慢的州正考虑放松环境保护法规—— 还是承认 environmental regulations promote (affect) growth ,因此跟主结论相悖了。
选了E,后来觉得应该选A E如果是“even those states with very weak environmental regulations have experienced as high growth as those with the strictest environmental regulations." 就选E。
