Volcanic eruptions can wreak havoc, but some regions are more vulnerable than others. Indonesia has the most active volcanoes and the highest death tolls due to the prevalence of violent composite volcanoes like Mount Marapi, which killed 23 in late 2022. Composite volcanoes spew thick lava that hardens rapidly, creating steep, cone-shaped mountains prone to explosive eruptions. In contrast, shield volcanoes like those in Iceland produce fluid lava that flows farther, forming gentle slopes. This makes eruptions less catastrophic. - [1] - Still, Iceland is not immune to volcanic impacts. When the Laki fissure erupted in 1783-84, the resulting pollution and famine killed over 20% of Iceland's population. Today, Iceland utilizes technology to monitor volcanoes and warn residents of impending eruptions. - [2] - Seismometers detect tremors signaling magma movement while satellites measure landscape changes. While these systems facilitated evacuation prior to the 2021 Fagradalsfjall eruption near Reykjavik, avoiding loss of life, the eruption still forced hundreds of residents to move away from their homes. -[3] - For communities living near volcanoes, establishing robust early warning systems and evacuation plans is crucial to reduce risk, as in Iceland. - [4]- Even when no lives are lost, longtime residents lament the destruction of their homes and way of life, as Grindavik native Siggeir experienced after the 1973 Eldfell eruption on Heimaey Island. Ultimately, while warning systems help communities physically survive eruptions, emotional and communal impacts still take a toll. - [5]-

What is the main idea of Paragraph 2?
- A Despite mitigation, Iceland is still volcanic-risk prone.
- B Unlike Indonesia, Iceland continues to face volcanic threats.
- C Because of attempts to minimize dangers, Iceland is free from the risk of volcanic events.
- D Apart from seismometers, Iceland use satellites to predict volcanic eruptions.
- E Despite preventive measures, Iceland remains susceptible to earthquake hazards.
思路引導 VIP
請觀察第二段的第一句話與最後一個例子：既然文中提到了冰島擁有先進的監控科技與預警系統，為什麼作者還要特別強調 2021 年居民仍被迫搬離家園的現況呢？這兩者之間的關係，如何對應到該段想要傳達的核心訊息？

段落主旨與論點推導
這段文字的開端以「Still（儘管如此）」作為轉折，銜接前一段對冰島火山性質較溫和的描述，隨即點出冰島並非對火山威脅免疫。文中雖然詳述了冰島如何利用地震儀（seismometers）與衛星（satellites）等高科技來監控並預警，但最後仍以 2021 年的噴發為例，說明即使避免了人命損失，居民仍被迫撤離家園。這正呼應了選項 (A) 的核心：即便有各種緩解措施（mitigation），冰島依然處於**火山風險（volcanic-risk prone）**之中。
