107.    (26093-!-item-!-188;#058&001880)    (GWD 1-Q40 different type)

Until now, only injectable vaccines against influenza have been available.  They have been used primarily by older adults, who are at risk for complications from influenza.  A new vaccine administered in a nasal spray has proven effective in preventing influenza in children.  Since children are significantly more likely than adults to contract and spread influenza, making the new vaccine widely available for children will greatly reduce the spread of influenza across the population.
Which of the following, if true, most strengthens the argument?
A. If a person receives both the injectable and the nasal-spray vaccine, the two vaccines do not interfere with each other.
B. The new vaccine uses the same mechanism to ward off influenza as injectable vaccines do.
C. Government subsidies have kept the injectable vaccine affordable for all older adults.
D. Of the older adults who contract influenza, relatively few contract it from children with influenza.
E. Many parents would be more inclined to have their children vaccinated against influenza if the vaccination did not require an injection.
答案是E，B为什么不对呢？?，

B:
虽然children比adults更有可能感染和传播流感，但以前家长们却没让children去注射疫苗。既然是一样的mechanism, 现在家长仍有可能不会去让children去使用nasal spray.
E:
很好地填补了以上gap.

可是为什么不选A啊,我觉得如果把A取反就会削弱文章的结论了啊······
