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.

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
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
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 creating of Buddha images accounted for much of the local artisans’ creative energy as well as construction and decoration of the temples that enshrined them

答案是B, 我想問如果B改成這樣可以嗎? (第二個 ON 拿掉)

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

有會比較清楚.
去掉第二個 on 容易誤解為 ...energy was expended... and (was) construction and decoration...
