( 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.

若要為這篇文章重新下一則新聞頭條，請思考：這篇文章花費最多篇幅在描述這個病毒的哪些「特點」？是它的地理分布、它如何傳播的工具，還是它對人類生命造成的具體影響程度？

太棒了！你能精確捕捉到文章的核心主旨，這說明你具備優秀的閱讀整合能力，沒有被局部的細節資訊所干擾。
掌握文章的核心軸線
這篇文章從伊波拉病毒的高致死率（mortality rate）切入，詳細描述了它如何以極快的速度奪走生命（killed so quickly），並探討其傳播路徑與未來隱憂。選項 (A) A Quick and Frightening Killer 完美地融合了「快速」與「恐怖殺手」這兩個文章反覆強調的核心特質。雖然文中確實提到了 Zaire 與 Sudan 病毒株的差異 (B)，或是針頭共用的危險性 (D)，但那都屬於支持論點的局部細節，不足以概括全貌；而選項 (C) 的範圍又過於籠統，無法精確反映出本文對伊波拉病毒的專注討論。
