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?
A. the amount of dangerous toxins contained in wood smoke is much less than the amount contained in an equal volume of automobile exhaust.
B. Within th jurisdiction covered by the proposed legislation, most heating and cooking is done with oil or natural gas.
C. Smoke produced by coal burning stoves is significantly more toxic than smoke from wood burning stoves
D. no significant beneficial effect on air quality would result if open-air fires were banned within the jurisdiction covered by the proposed legislation
E. in Vallays where wood is used as the primary heating fuel, the concentration of smoke results in poor air quality

.......
正确答案是E
我最开始选的B，后来觉得E的确更好的支持了之前的argument
但是我不明白为什么答案说B 的point suggests less of a need for legislation.
B说有政府政策监管的地区使用更多的油或者天然气来取暖或者做饭。那不应该是比用木头燃烧要更环保么？那岂不是可以达到目的少用木头燃烧？虽然题目里没有提到用天然气或者油会更环保
但是好像又说的通如果说有政策的地区大部分人用油或者天然气政策根本没有用（没有regulate the use of open air fires and wood burning stoves?）

所以我想请教一下我这种想法正确吗？
或者还有没有其他更好的思路来解决这道题？

万分感谢！

B的意思是在建议立法的辖区，多数的取暖和炉灶都是烧油和天然气的。这是proposed legislation地区的特点，有这个特点不就不用立法限制 use of open air fires and wood burning stoves了吗？
在人们都用枪的美国，立法限制管制刀具有啥用？
