His studies of ice-polished rocks in his Alpine homeland, far outside the range of present-day glaciers, led Louis Agassiz in 1837 to propose the concept of an age ( in which great ice sheets had existed in now currently temperate areas. )
A in which great ice sheets had existed in now currently temperate areas
B in which great ice sheets existed in what are now temperate areas
C when great ice sheets existed where there were areas now temperate
D when great ice sheets had existed in current temperate areas
E when great ice sheets existed in areas now that are temperate
答案是D,错选了B。BD纠结,不知道该如何判断。第二遍做这道题还是把握不好句意,麻烦老师讲解。

请问这题中“explore”的动发者为什么是“Lina”呢?我在读A选项时总觉得选项中explore的动发者是“A group of films” 因为觉得explore前面的主体是“A group of films”, 而 in 1970 和 Lina 都是修饰films的。
