问题 This passage mainly discusses how epidemics spread and how to prevent in advance. [br] When there are no efficient doctors in areas of large population, epidemics can break out.

选项 A、Y
B、N
C、NG

答案 B

解析 本题涉及到爆发流行病的条件,应锁定文章第一段。第一段依次列举了爆发流行病的所有必备条件,并在段末指出:When these conditions are present in large population centers, epidemics can start,即当所有这些情况都具备于人口聚集区时,流行病才可能爆发。题干中的no efficient doctors对应文中的doctors does not know how to treat the disease,但其只是上述条件中的一点,不足以构成流行病爆发的所有条件,因此题干表述与原文不符。
