标题: 800软件上的有道逻辑题求解

2、Smoking in bed has long been the main cause of home fires. Despite a significant decline in cigarette smoking in the last two decades, there has been no comparable decline in the number of people killed in home fires. Each one of the following statements, if true over the last two decades, helps to resolve the apparent discrepancy above EXCEPT:

A) Compared to other types of home fires, home fires caused by smoking in bed usually cause relatively little damage before they are extinguished.

B) Home fires caused by smoking in bed often break out after the home's occupants have fallen asleep.

C) Smokers who smoke in bed tend to be heavy smokers who are less likely to quit smoking than are smokers who do not smoke in bed.

D) An increasing number of people have been killed in home fires that started in the kitchen.

E) Population densities have increased, with the result that one home fire can cause more deaths than in previous decades.

个人分析题目是：问题：在“在床上吸烟是造成的居民户火灾的主要原因”这个前提下，吸烟人数减少**，但在火灾中死亡人数却未减少**，****有矛盾，找出不能解决矛盾的说法。
个人认为，A项不能解决矛盾，可是答案是B。
答案：(B) What does NOT resolve the apparent paradox? The paradox is that smoking has declined, yet fatalities from home fires have increased. Therefore, we are looking for an alternative cause of fires or that smoking is not related to home fires. (B) does not resolve the paradox; it simply reinforces the fatality of smoking. (A) would explain the paradox because it shows that the fires are rarely fatal. (C) resolves the paradox because it suggests that the reduction in smoking rates haven't reduced the fatality rates. (D) resolves the paradox because it finds alternative causes for the fires. (E) explains the paradox by suggesting fires have become more fatal, despite declining smoking rates.

我理解了一下答案，觉得可以这样理解，A项说smoking in bed引起的火灾造成的damage很小，所以应该不会造成很大的人员伤亡，所以造成20年来home fire伤亡人数不变的原因不是smoking in bed，有其他原因，也就是说，即使吸烟的人少了，伤亡人数仍可以很多，所以A项可解释。
但是，那B项也可以解释啊，因为火灾是发生在睡觉以后，所以造成的伤亡比较大，所以即使发生的起数变少了，总伤亡数不变。
嗯，在打这道题的时候，我突然想到B错在何处，不知是否正确。就是说吸烟人数为减少时和吸烟人数减少后，火灾都是发生在睡觉以后，都会造成大伤亡，所以既然这个条件在不同环境中是一样的，就不能用做不同现象的原因解释。跪求各位指导！
