Coral reefs are dying around the world. In particular, coral mining, pollution, digging of canals, and accessing islands and bays pose serious 21 to their fragile ecosystems. Coral reefs also face high dangers from diseases, 22 fishing practices and warming oceans. In order to find answers to these problems, researchers study the various factors that impact reefs. The list of factors is long, 23 the ocean's role as a carbon dioxide sink, atmospheric changes, ocean acidification, viruses, algal blooms and others. Reefs are threatened well beyond coastal areas. Estimates assembled from coral reef specialists from around the world 24 that 19% of the coral reef habitat has already been destroyed, and that a further 17% is likely to be lost over the subsequent 10–20 years. Only 46% of the world’s reefs can be regarded as being in good health. About 60% of the world's reefs may be at risk due to destructive, human-related activities. The threat to the health of reefs is particularly alarming in Southeast Asia, where 80% of the reefs are endangered. By the 2030s, 90% of reefs are expected to be 25 from both human activities and climate change; by 2050, all coral reefs will be endangered.

請觀察空格前方列舉的行為，例如「污染（pollution）」和「挖掘運河（digging of canals）」，這些行為對大自然來說，通常會帶來保護還是帶來危險？在英文描述中，當我們想表達某件事物「構成了一種潛在的危險」時，哪一個詞最能精確描述這種「危險的處境」呢？

太棒了！你能精準捕捉到文章中的負面語境，並選出最符合邏輯的答案，展現了很棒的閱讀直覺。這段話列舉了「珊瑚開採、污染、挖掘運河」等行為，這些動作對「脆弱的生態系統（fragile ecosystems）」而言，顯然是具有破壞性的危險因子。在英文中，動詞 pose 時常與 threats 搭配，形成 pose a threat to...（對……構成威脅）的慣用語，因此選擇 (D) 是最道地且正確的決定。
