The disappearance of the glaciers will also leave a significant 29 impact.
答案：(A) cultural
下一句說明冰原對巴布亞原住民而言是神聖象徵，可知冰河消失帶來的是「文化」層面的衝擊；句中的 also 也顯示這是有別於前文環境衝擊的另一種影響，故 environmental 不合，moral（道德）與 political（政治）都無文內依據。
答對率 35%。
題目在講冰河消失，你大概直覺選 environmental。但句中的 also 是關鍵——它代表「除了前面已經談過的影響，還有另一種」，前文談的正是環境層面，所以這一格必須是環境以外的。
For many indigenous Papuans, the ice sheets represent a sacred symbol.（對許多巴布亞原住民而言，這些冰原是神聖的象徵），下一句還說山谷是神的四肢、冰河是神的頭——這些都屬於文化層面。
看到 also、another、in addition，先問「前面講過哪一種了」，答案通常是還沒講過的那一種。
have a significant impact on（對…有重大影響）、cultural／environmental impact（文化／環境衝擊）、indigenous people（原住民）。
Glaciers are usually associated with colder climates. But some mountain ranges of South America, Africa, and Indonesia are also 26 glaciers and ice sheets. These tropical glaciers serve as a major source of water supply to one-sixth of the world's population.
A newly published study, however, revealed that rising temperatures are posing an 27 threat to the last tropical glaciers in Indonesia's Papua region. The ice sheets, which once spanned 20 square kilometers, are thinning over five times as quickly compared to a few years ago. 28 already shrunk by 85 to a mere 0.5 square kilometers, Papua's glaciers will completely disappear within a decade, researchers have predicted.
The disappearance of the glaciers will also leave a significant 29 impact. For many indigenous Papuans, the ice sheets represent a sacred symbol. "The mountains and valleys are the arms and legs of their god and the glaciers are the head," explained the head researcher. The study warned that Papua's glaciers are only the "first to go" if greenhouse gases are 30 and temperatures continue rising. And this is certainly a serious warning about the depressing fate of other glaciers around the world.
