Wood smoke contains dangerous toxins that cause changes in human cells. Because wood smoke presents such a high health risk, legislation is needed to regulate the use of open-air fires and wood-burning stoves.
Which of the following, if true, provides the most support for the argument above?
The amount of dangerous toxins contained in wood smoke is much less than the amount contained in an equal volume of automobile exhaust.
Within the jurisdiction covered by the proposed legislation, most heating and cooking is done with oil or natural gas.
Smoke produced by coal-burning stoves is significantly more toxic than smoke from wood burning stoves.
No significant beneficial effect on air quality would result if open-air fires were banned within the jurisdiction covered by the proposed legislation.
In valleys where wood is used as the primary heating fuel, the concentration of smoke results in poor air quality.

再做又错……是因果推理，E选项加强了因果联系
问哪一选项可以加强。D选项取非之后是加强不是削弱啊，所以不对
感觉应该是因果推理，感觉ABCD都是在加强，只有E实在削弱。
方案推理不对，如果是方案推理那么CQ就要讨论方案上，及立法是否有效，可行，否定性副作用
我觉得这题是因果推理： 因：立法管制open-air fires 和 wood-burning stoves； 果：人们受到toxin危害的risk会减少。E选项从反方面说明，不管制这两种行为，空气质量会变差。反过来就是说，管制这两种行为，空气质量会变好，加强果。 其实这题用方案推理我觉得也ok啦。。。
