Microscopic plants called algae grow inside the top layer of sea ice in the Antarctic if enough sunlight reaches that layer of ice and enough seawater, which contains nutrients, reaches that layer after splashing onto the surface. Even though moderate snow cover reduces the sunlight that filters into the top layer, sea ice with moderate snow cover typically contains even more algae in the top layer than does sea ice with less snow cover.

Which of the following, if true, most helps to explain the apparent discrepancy?

(A) As the weight of accumulated snow forces ice lower in the water, more seawater splashes onto the surface and seeps through the snow.
(B) Seawater in the Antarctic often contains higher concentrations of nutrients than does seawater in more temperate regions.
(C) As the air temperature around sea ice decreases during the winter, the likelihood decreases that snow will fall and thus add to any existing snow cover.

當空氣中的溫度在海上的冰塊週遭下降在冬天時, 可能性降低了@#@$%$% 不知道怎樣翻這句話? 倒裝? 又不像? likelihood解釋成前面一整句? 也怪怪的.

(D) The nutrients on which algae rely are common in seawater throughout the Antarctic.
(E) More sunlight filters through a layer of ice than through an equally thick layer of snow.

這一題我答對, 但是想知道C到底在說什麼?

題目問為什麼表面雪層多的藻類比表面雪層少藻類的數量多?

海面溫度下降,減少雪量的可能性會下降,因此增加表面的雪層=>非議題焦點 還是沒解釋到原因

個人淺見

[chris8888]

我懂了, 這是倒裝句
the likelihood decreases that snow will fall and thus add to any existing snow cover.
that萬不可能修飾V -- decrease
=> the likelihood that snow will fall and thus add to any existing snow cover decreases.

所以降雪機率的高低無法解釋此題的問題.

請問這題正確答案是A嗎？
謝謝！
