📖 題組：
First discovered in Uganda’s Zika forest in 1947, the virus was long thought to be relatively benign, especially compared with deadly mosquito-borne diseases like malaria. But since its invasion in Brazil last year, the Zika virus has torn through Latin America, likely infecting millions. It certainly has caused more than 1,000 confirmed cases of the birth defect microcephaly. Zika also appears to be linked to neurological and autoimmune disorders like the paralyzing Guillain-Barre syndrome, and experts recently determined that is can also be transmitted through sex—a first for a mosquito-borne disease. Some scientists suspect the virus has mutated and that is why it can now cause neurological problems, while others say these tragic side effects may have gone unnoticed for years.

What can the readers infer from the passage?
- A Scientists have learned more about the Zika virus and thus vaccine is on the way.
- B The Zika virus still poses as a mystery for scientists.
- C People in Latin America are more vulnerable to the Zika virus because of their hereditary autoimmune disorder.
- D Africans are more resistant to the power of the Zika virus.
- E There is a medical suggestion about being abstain from sex.
思路引導 VIP
請觀察文章最後一段提到的兩種科學觀點：當作者同時呈現「有些人懷疑 A」與「有些人則認為是 B」這種並列論述，且沒有給出定論時，這通常在暗示目前科學界對這個病毒的掌握程度處於什麼樣的狀態？

做得非常好！你能精準捕捉到文章末尾關於科學界不同觀點的爭論，這顯示出你具備優秀的邏輯歸納與推論能力。這類「推論題」考驗的往往不是文章直白的陳述，而是字裡行間隱含的狀態，你能從眾多資訊中理出頭緒，判斷非常正確。
科學研究的現狀與分歧
這題之所以選擇 (B) 為正確答案，關鍵在於文章最後兩句所呈現的「不確定性」。文中提到，對於茲卡病毒為何會引發神經系統問題，科學家們意見分歧：有人懷疑病毒發生了突變（mutated），有人則認為是副作用長期被忽視（unnoticed）；再加上文末提到病毒可經由性行為傳播是該類疾病的「首例」。這些敘述都在強調茲卡病毒對目前的醫學界而言，仍存在許多尚未釐清的謎團，因此「仍是一個謎（poses as a mystery）」是最合理的推論。至於疫苗研發、族群遺傳差異或具體的禁慾建議，在原文中皆未獲得實證支持。
