A << H,
A&H = 95% A << 95% H

E

剛好做到這一題

題目最後一句：Fact: Over 95 percent of people who have asthma also suffer from hay fever
95%的人有氣喘，這些人也會對花粉症感到不適應

E. 的答案最接近主題所要求的support.

因為：95%的人有氣喘也會對花粉症感到不適應，則剩下的5%的人就是沒有氣喘的。
　　　但是這5%當中也許包含有得了花粉症的人，或，也許沒有得花粉症的人。
　　　如果這5%的人當中真的有人得了花粉症的話，5%得花粉症的人有可能會多於95%中有得花粉症的人，或，也有可能是低於95%中有得hay fever的人。

看來看去，E　的選項最接近了，因為有提到是低於的現像。

D選項，比較樣本不同，所以不選。

小小淺見，供參考
