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.
OA:E 有人能帮我详细讲解一下这题吗？谢谢啦

题目说要让这种喷鼻剂available for children 以防止流感传播  但是availble只是必要条件 children必须得vaccinate啊 E提供了这一条件的可能性

ls让我有点明白了，谢谢啦~
本题结论是：making the new vaccine widely available for children will greatly reduce the spread of influenza across the population.
E说父母更愿意让自己的孩子接种疫苗NEW VACCINE，直接支持A可行。

open to discuss...

我也想问.. D和E..

原文的结论是：新的疫苗可以大大降低疾病传染。但有个逻辑断层，即孩子必须愿意接受这个新的疫苗啊！如果孩子都不肯用喷雾，那么结论就不成立了~
而E选项说如果可以不打针，父母会更加倾向于让孩子使用这种疫苗，即通过spray。就弥补了上述的逻辑断层，支持了这个argument。反观D选项，说生病的老人中，很少是受到孩子的传染，是削弱原文啦！不是加强！因为如果不是传染自孩子，那么这个新的疫苗即使用于孩子，也不会导致reduce the spread
