(A) 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

(D) creating images of Buddha accounted for much of the local artisans’ creative energy, and also constructing and decorating the temples enshrining them
(E) the creation of Buddha images accounted for much of the local artisans’ creative energy as well as construction and decoration of the temples that enshrined them
选项分析：
(A)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
【错误1】 平行结构：“and”两边连接的是“when……”引导的从句和“the creation of……”两者语法功能不一致。
【错误2】 代词指代：“they constructed and decorated the temples that enshrined them”中“they”和“them”指代对象不同，同类代词在句子中发福出现如果指代对象不相同，则存在指代不明的问题，表意不佳。
(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
【正确】 “on the creation of Buddha images”和“on construction and decoration of the temples”正确地用“and”平行在一起。
【大意】 在古泰国，当地工匠大量的创造力发挥在了佛像的建造以及供奉佛像的庙宇的建造和装饰上。
(C)much of the local artisans' creative energy was expended on the creation of Buddha images as well as constructing and decoration of the temples in which they were enshrined
【错误】 平行结构：“contruct”拥有自己的专有名词“construction”，因此应当“construction”和“decoration”平行，无需“constructing”。
(D)creating images of Buddha accounted for much of the local artisans' creative energy, and also constructing and decorating the temples enshrining them
【错误】 平行结构：“constructing and decorating”本应和“creating images”平行在一起，而本选项却错误地将其与“creative energy”平行。
(E)the creation of Buddha images accounted for much of the local artisans' creative energy as well as construction and decoration of the temples that enshrined them
【错误】 平行结构：类似地，见(D)。
解题思路：
只有(B)正确使用平行结构，表达出合理的含义，因此选择(B)。
