GWD3-Q41

GWD3-Q41:  

In ancient Thailand, much of the local artisans’ creative energy was expended for the creation of Buddha images and when they constructed and decorated the temples that enshrined them.

B.       much of the local artisans’ creative energy was expended on the creation of Buddha images and on construction and decoration of the temples in which they were enshrined

 答案是B,

 其中THEY指代什么？ 请NN帮个忙。 

这里的they应该优先指代主语

但是主语energy（单数），故不成立

如果无法指代主语，接着优先指代的应该是宾语，这里的宾语是images

images在逻辑上可以被enshrined修饰，故they指代images

they指代images。

当然，选项B也可以根据平行结构进行选择。
