GWD :12-Q38 Outbreaks of Rift Valley fever occur irregularly in East Africa, several years apart. When outbreaks do occur, they kill thousands of cattle. A livestock vaccine against the disease exists but is rarely used. It is too expensive for farmers to use routinely, and since it is not effective until a month after vaccination, administering it after an outbreak begins helps very little. Nevertheless, experts predict that use of the vaccine will increase significantly within the next few years. Which of the following, if true, provides the strongest justification for the experts’ prediction? A. Rift Valley fever is spread by mosquitoes, but each outbreak is so widespread that it is impractical to control it by using insecticides. B. When an outbreak of Rift Valley fever occurs, unaffected countries often refuse to import livestock from the countries affected by the outbreak. C. It would take less than a month for producers of the vaccine to adjust their production operations to cope with a large increase in demand. D. Many cattle farmers in East Africa are nomadic or live in remote villages, and such farmers, who have little access to modern veterinary medicine, are particularly hard hit by outbreaks of Rift Valley fever. E. Recently published research has shown that certain identifiable climatic conditions are almost invariably followed, within two to five months, by an outbreak of Rift Valley fever. ANS:E 作了那麼多題目後，只要找到KEY"通常可以答題很快但這題我覺得(B)很像KEY，因為我以為這題是針對"$"來的，很快可以削弱。我也了解E對的原因，但是B到底錯的點會是什麼? 無關嗎有些貌似無關的卻也有可能是正確答案。唉~ 謝謝耐心看完^^ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 124.8.5.235
