of allergy. Their research confirms that it is not just caused by pollen of a certain flower, as it was thought. In addition, the flower has to be pollinated by a certain kind of bee to cause the allergy.

Which of the following would most likely support the data's implication?


    A.In the absence of the bee, the pollen does not cause allergic reactions. 

    B.The bee has been shown to be a critical element in the reproduction of the particular flower. 

    C.Many cases of the allergy have been observed only in the presence of the bee.  

    D.In cases in which the allergy does not develop, the flower will grow without the presence of the bee.  

    E.The onset of the allergy is usually caused by the flower even if the pollen is not present.

A

研究发现

一种新型的过敏并不仅仅是由花粉引起的,而且花粉靠蜜蜂传播引起过敏,问结论。

过敏由花粉引起,花粉由蜜蜂带来,因此能够得出蜜蜂才是导致过敏的原因

A 没有蜜蜂,花粉不会导致过敏。正确,因为花粉并不是导致过敏的真正原因

B 蜂蜜在花产生的过程中起着重要作用。花的产生,无关选项

C 过敏案例在蜜蜂在的时候才被研究。明显实验方法的错误,既然蜜蜂是关键原因,那必定有蜜蜂在或者不在的对比实验

D 没有过敏的时候,没有蜜蜂花也会生长。未知

E 即使没有花粉,过敏也可能由花直接导致。未知
