26. Smoking in bed has long been the main cause of home fires. Despite a significant decline in cigarette smoking in the last two decades, however, 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.
答案：B，我选了C，我觉得B，C都不能解释。

18. Each child in a group of young children read aloud both a short paragraph and a list of randomly ordered words from the paragraph. The more experienced readers among them made fewer pronunciation errors in whichever task they performed second. Whether it was the list or the paragraph. The order in which the two tasks were performed, however, had no effect on the performance of beginning readers, who always made fewer pronunciation errors when reading the paragraph than when reading the list.
Which one of the following, if true, most helps to explain why the order in which the tasks were performed was not significant for the beginning readers?
(A) Because several words were used more than once in the paragraph but only once in the list, the list, the list was shorter than the paragraph.
(B) In reading the paragraph, the more experienced readers were better at using context to guess at difficult words than were the beginning readers.
(C) The more experienced readers sounded out difficult words, while the beginning readers relied solely on context to guess at difficult words.
(D) Both tasks used the same words, so that the words the children read in whichever task was performed first would be recognized in the second task.
(E) The beginning readers made more pronunciation errors than the more experienced readers did in reading both the paragraph and the list.
答案：C，我选了D，我觉得D也可以解释啊。
谢谢。
1. notice the discrepancy: bed cigarette smoking the most cause of fire... important while the cigarette smoker decline, the number of people killer in home fires has not decline accordingly.
C tell us that though the number of cigarette smoker decline, the number of cigarette smokers, who are the most important contributor to the fire, has not droped down...so it can explain the reason that people killed in home fires has not decline..
2. when you want to make an explaintion of an paradox, you should focus on the discrepancy. D only explain the reason why experienced boys can make progress, but can't explain the reason that less experienced boys make fewer errors in passage..
only C, tell us the cause of the differences.
