问题 The passage suggests that a lack of modern sanitation would make which of the following most likely to occur? [br] Which of the following can most reasonably be concluded about the mosquito Aedes albopictus on the basis of information given in the passage?

选项 A、It is native to the United States.
B、It can proliferate only in Asia.
C、It transmits the dengue virus.
D、It caused an epidemic of dengue hemorrhagic fever in the 1950’s.
E、It replaced Aedes aegypti in Asia when ecological changes altered Aedes aegypti’s habitat.

答案 C

解析 The best answer is C. Lines 26-29 state that the presence of Aedes albopicturs creates the risk of a dengue epidemic, thus implying strongly that the mosquito is a carrier of the disease. Choices A and B are directly contradicted by the passage, which states that the mosquito was introduced into the United States inadvertently and that it has proliferated widely there. The passage attributes the dengue epidemic of the 1950’s to Aedes aegypti, not Aedes albopitus, making choice D incorrect. Choice E is incorrect because the passage does not discuss the ecological relationship between the two mosquitoes.
