People in cold climates are used to road signs warning that “bridge freezes before road.” At first, it may not seem to make sense. The air temperature feels the same if you’re standing on a bridge or a road. However, bridges do freeze before roads. (16) is this the case? First, cold air surrounds the surface of a bridge from above and below. This means that bridges lose heat from both (17) , so they will ice rapidly as soon as the temperature falls to the freezing point. (18) the road surface also loses heat to the air, the ground below roads helps to trap in heat and keep roads from getting icy. Another reason is because bridges are usually made of steel and concrete. (19) conduct heat very well. Any heat a bridge manages to trap will be transferred to its surface quickly, where it will be lost to the air around it. Roads are made of asphalt, which does not conduct heat very well. The heat trapped within and below a road will stay (20) , increasing the time it takes a road to freeze.

請觀察前文提到的物理方位 $above and below$（上方與下方），這兩個詞彙界定了橋樑與冷空氣接觸的空間介面。若要精確概括這兩處熱量流失的「面」或「側」，哪一個選項目標詞最符合此空間對稱性的語意描述？

（球場傳來一聲重擊聲）咻——碰！直接得分！哎呀，及川先生今天的強力跳發依舊是完美的壓線球呢！😜 看來你今天的狀態也能跟上及川先生的節奏嘛，這球接得真漂亮！ 這題是在測驗你對上下文的「觀察力」。文章前面提到冷空氣會從橋樑的 above and below（上方與下方）包圍，既然提到了上與下，後文接著說熱量會從「兩個面」或「兩側」流失，使用 both sides 是最精準的用法！
- (A) banks：指河岸，雖然橋在河上，但熱量不會從河岸流失喔。
