Which of the following, if true, provides evidence that most logically completes the argument below?
According to a widely held economic hypothesis, imposing strict environmental regulations reduces economic growth. This hypothesis is undermined by the fact that the states with the strictest environmental regulations also have the highest economic growth. This fact does not show that environmental regulations promote growth, however, since ______.
- those states with the strictest environmental regulations invest the most in education and job training
- even those states that have only moderately strict environmental regulations have higher growth than those with the least-strict regulations
- many states that are experiencing reduced economic growth are considering weakening their environmental regulations
无关
- after introducing stricter environmental regulations, many states experienced increased economic growth
不构成因果关系，与原文衔接不上
- even those states with very weak environmental regulations have experienced at least some growth与原文衔接不上
答案是A,可是我怎么看都怎么觉得A是无关选项,而且意思特别绕.请大牛指点 |
