Can someone please help me with an answer and an explanation to this question. Thanks.

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.

B

The paradox is that smoking in bed causes home fires and while cigarette smoking has decreased, deaths from home fires have not. Were looking for the answer that does NOT resolve this paradox.

A) This tells us that the fires caused by smokers in bed do not kill people therefore explaing the decrease in smokers hasnt lead to a decreas in deaths.
C)This tells us that while smoking has decreased the people who smoke in bed probably hasnt therefore expaining why there is no decrease in deaths.
D)This tells us that more people are dying from kitchen fires explaining why there is no decrease in deaths.
E)This tells us that more people live in one house explaining why there could be less fires but yet still no decrease in deaths.

B)This tells us that the fires from smokers in bed happen after they are asleep which actually strengthens the paradox.

A: says that smoking in bed fires did little damage, thus didnt really anyone. So the discrepency is somewhat explained.
C: explains the discrepency b/c heavy smokers didn't quit, so of course the number of household deaths from smoking in bed wouldnt drop much
D: decreased in one type of fire, but could make up for it in another type
E: explains more deaths occur

B: doesnt really add anything but detailed info on how the fires come about.

Analysis: Eliminate all the answer choices that explains deaths caused by home fires
Analysis: Eliminate all the answer choices that explains deaths caused by home fires

A) Compared to other types of home fires, home fires caused by smoking in bed usually cause relatively little damage before they are extinguished. (This explains why other fires are difficult to extinguish and potentially cause major damages – eliminate it)

B) Home fires caused by smoking in bed often break out after the home's occupants have fallen asleep. (When fire breaks out doesn’t explain about increase in number of deaths – Hold it)

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. (Irrelevant to discussion –eliminate it)

D) An increasing number of people have been killed in home fires that started in the kitchen. (Explains why high death numbers – eliminate it)

E) Population densities have increased, with the result that one home fire can cause more deaths than in previous decades. (Explains why high death numbers – eliminate it)

Answer: B
