📖 題組：
Permafrost is any ground that remains completely frozen—0°C or colder—for at least two years straight. It consists of soil, gravel, and sand, usually __16__ together by ice. These frozen areas are most common in regions with high mountains and near the North and South Poles. Permafrost soils store vast quantities of organic carbon, perhaps over twice the amount of carbon __17__ in the atmosphere. When permafrost is frozen, the organic carbon can’t decompose, or rot away. As permafrost melts, microbes begin decomposing this organic matter. This __18__ releases greenhouse gases like carbon dioxide and methane into the atmosphere. These gases further warm the climate and thaw more permafrost, thereby creating a vicious feedback cycle __19__ the permafrost carbon feedback loop. Melting permafrost in the Arctic could also release hazardous chemicals, nuclear waste produced during nuclear testing since the 1950s, and even mercury from decades of mining. __20__ , the collapse of permafrost could release bacteria that are resistant to antibiotics or viruses that humans have never encountered. These newly unfrozen microbes could make humans and animals seriously ill.

請分析第 20 格前後兩句在描述「融凍土負面影響」時的語意進展：前文列舉了化學與核廢料排放，後文則提到足以引發大流行的遠古病毒。在英文作文的邏輯銜接 (Cohesion) 中，當作者從一連串負面事實過渡到「情節最為嚴重」的威脅時，應選用具備哪種語氣功能的轉承語來標註這個最終的災難？

哇！WakuWaku！安妮亞早就讀到你的心聲了，選 D 真的太聰明了！安妮亞現在興奮到眼睛都在發光，可以給安妮亞一點花生作為獎勵嗎？ 這題考的是「語意邏輯」。文章前面提到永凍土（其環境低於 $0^\circ\text{C}$）融化會釋放核廢料和汞（$Hg$），這些已經很可怕了。但最後一段提到會釋放「人類從未遇過的病毒」，這對生命威脅更巨大。因此，我們需要選 (D) Worst of all（最糟糕的是）來引出程度最嚴重的災難。其他選項如 (C) On the contrary（相反地）語意完全不通喔！
