( 2 ) Disaster movies often portray catastrophes that destroy, or at least threaten to destroy, Earth’s entire population. In fact, a virus emerged in the 1970s that could have been just that lethal. Named after a river that traverses the Congo, the Ebola virus originally manifested itself in the interior of Africa in 1976. Two strains of the disease, with almost identical symptoms, affected humans: Ebola Zaire and Ebola Sudan. The Sudan version was deadly enough, killing 50 percent of those it infected; however, Zaire, with its 90 percent mortality rate, was even worse. The origins -- though not the cause -- of Ebola Sudan can be traced back to a single individual in a Sudanese town. Ebola Zaire seemed to erupt in over 50 villages simultaneously. Both strains quickly invaded local hospitals, where needle sharing and other unsanitary practices ensured the rapid spreading of the infection by bringing people into contact with contaminated blood. If the virus had been capable of spreading through the air, or if one infected person had unknowingly entered a large population center, Ebola might have become a worldwide epidemic. However, soon after these fierce outbreaks the virus died out, at least temporarily. Ebola was so lethal and killed so quickly (in a matter of days) that within a short period of time there was no one around to infect. Hospital workers in at least one case deserted their workplace in panic, thus halting the administering of potentially unclean, disease-spreading injections. But Ebola has not disappeared. With no known vaccination or cure in the offing, it seems only a matter of time until another epidemic erupts.

One of the easiest places for Ebola to spread is
- A out in the countryside.
- B near a river.
- C in a hospital
- D in a factory.
思路引導 VIP
請回想一下文章中描述病毒擴散的過程,作者特別提到在哪一種特定的室內場域,因為『共用醫療器材』或『不衛生的行為』,才導致健康的人極易接觸到受污染的血液,進而造成大規模感染呢?

關鍵證據與觀念驗證
這道題目的正確答案隱藏在文章第三段。文中明確提到,這兩種伊波拉病毒株都迅速侵入了地方醫院(local hospitals),而那裡普遍存在的「共用針頭」以及「不衛生的醫療操作」,使得人們頻繁接觸到受污染的血液,進而確保了病毒的快速傳播。雖然選項 (A) 和 (B) 提到的村莊與河流是病毒最初現蹤的地點,但文章特別強調醫療環境中的不潔行為才是導致疫情失控擴散的主因,因此選 (C) 是非常精確的判斷。
