Wood Smoke contains dangerous tocins that cause changes in human cells. Becasue wood smoke presents such a high health rish, legislation is needed to regulate the use of open-air fires and wood-burning stoves
Which support the argument?
B) Within the jurisdiction covered by the proposed legislation, most heating and cooking is done with oil or natural gas
Why this answer is wrong?? I think it dose support the arugment cuz it saying the for those areas that have the legislation, heating and cooking is by other methods not wood-burning.
