Q12:
A mosquito bite can transmit to a person the parasite that causes malaria, and the use of
mosquito nets over children’s beds can significantly reduce the incidence of malarial
infection for children in areas where malaria is common. Yet public health officials are
reluctant to recommend the use of mosquito nets over children’s beds in such areas.
13
Which of the following, if true, would provide the strongest grounds for the public health
officials’ reluctance?
A. Early exposure to malaria increases the body’s resistance to it and results in a
lesser likelihood of severe life-threatening episodes of malaria.
B. Mosquito bites can transmit to people diseases other than malaria.
C. Mosquito nets provide protection from some insect pests other than mosquitoes.
D. Although there are vaccines available for many childhood diseases, no vaccine
has been developed that is effective against malaria.
E. The pesticides that are most effective against mosquitoes in regions where malaria
is common have significant detrimental effects on human health.

怎么还能reluctance呢？增加抵抗力，导致致命疟疾发生的可能性更少?

不是么？

答案给的a

我选的c

是不是C? 因为原文是"and the use of
mosquito nets over children’s beds can significantly reduce the incidence of malarial
infection for children in areas where malaria is common" 没有说可以防蚊.
