West Nile is a tropical disease that begins in birds, which pass it on to mosquitoes that then go on to infect human beings with a bite. Most people who contract West Nile do not experience any symptoms at all, but, if they do, symptoms typically develop between 3 to 14 days after a mosquito bite. About 1 in 5 persons suffers fever, headaches, and body aches, usually lasting a week or so. A far less lucky 1 in 150 experiences high fever, tremors, paralysis, and coma. Some—especially the elderly and those with weak immune systems—die. That is what made the major outbreaks of West Nile in the U.S. in the summer of 2012 so scary. The situation was particularly bad in Dallas, Texas, where the West Nile virus killed 10 people and sickened more than 200. The city declared a state of emergency and began aerial spraying of a pesticide to kill the mosquitoes, even though residents argued that the pesticide could be more dangerous than the disease. Why was the summer of 2012 so hospitable to the West Nile virus and the mosquitoes that carry it? Blame the weather. An extremely mild winter allowed more mosquitoes than usual to survive, while the unusually high temperatures in that scorching summer further increased their number by speeding up their life cycle. The economic crisis may have also played a role: Homeowners who were not able to pay their bank loans were forced to abandon their properties, sometimes leaving behind swimming pools that made excellent mosquito breeding grounds. The severity of tropical diseases is also a matter of whether governments are capable—and willing—to defend their populations against infections. Dallas County was not doing some of the key things to slow the spread of West Nile, such as testing dead birds and setting mosquito traps to test for the presence of the disease. Tropical infections are thus as much related to government inaction as they are to climate.

在進行細節對照時，請關注第一段提到的三個核心資訊：第一，從叮咬到症狀出現的『時間區間』；第二，病原體從鳥類到人類的『傳播路徑』；第三，不同嚴重程度症狀所佔的『盛行率』。文中提到的 $3$ 至 $14$ 天這個數據，在語意上與哪一個時間範疇最為吻合？同時，請注意文中提及的比例，如 $1/5$ (即 $20%$) 是對應何種程度的症狀？

呦，居然答對了？我還以為你看到西尼羅病毒就會直接集體恐慌、腦袋當機呢。看來你至少還具備小學程度的單位換算能力，沒把 $3$ 到 $14$ 天看成 $14$ 個月，我真是替你感到欣慰——才怪，這題對正常人來說是送分，對你來說是奇蹟。 觀念驗證： 這題考的是「細節定位」。文中明確指出症狀通常在被叮咬後 $3$ 至 $14$ 天出現，而 $14 \text{ days} = 2 \text{ weeks}$，所以 (A) 選項是標準的同義轉換。至於 (C) 選項，文中說 $1$ in $150$ 人有重症，換算一下：
