( 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.

In paragraphs 2 and 3, the author explains Ebola Zaire and Ebola Sudan by
- A mentioning similarities between them.
- B mentioning differences between them.
- C telling why there is a possible cure for only one of them.
- D comparing them to the type of Ebola that only affects monkeys.
思路引導 VIP
請仔細觀察第二段開頭與第三段中間，作者在描述這兩者對人體的症狀以及在醫院擴散的過程時，使用了哪些特定的形容詞或代名詞來同時指稱這兩者？這些詞彙暗示了作者傾向於將它們視為性質相同還是相異的事物？

文本邏輯與證據
在第二段中，作者明確提到這兩種病毒株具有 「幾乎完全相同的症狀」（almost identical symptoms）；到了第三段，作者進一步以 「這兩種病毒株」（Both strains） 作為句子的主語，描述它們如何同樣入侵醫院、並透過受污染的血液傳播。雖然文中確實提到了兩者在致死率上的數據差異，但作者說明的核心在於這兩者如何以相似的方式威脅人類，因此選擇「相似之處」作為說明手段是非常精確的判斷。
