In an attempt to attract more tourists, the Swiss government commissioned several life-size fiberglass cow statues, having them decorated by local artists, and set them up on the streets of Zurich.

A. the Swiss government commissioned several life-size fiberglass cow statues, having them decorated by local artists, and
不平衡
B. the Swiss government commissioned several life-size fiberglass cow statues, they were decorated by local artists, and then
C. the Swiss government commissioned several life-size fiberglass cow statues, had them decorated by local artists, and

D. several life-size fiberglass cow statues were commissioned by the Swiss government, decorated by local artists, and then
根據句意主詞應該是the Swiss government 為主詞

E. several life-size fiberglass cow statues, commissioned by the Swiss government, were decorated by local artists, and they
同D

正確選項C
為何用had
想請教一下 B為何錯

[chris8888]

have 使役動詞變成過去是had, 要求他們被裝飾, 被當地的藝術家

[dibert8]

B. the Swiss government commissioned several life-size fiberglass cow statues, they were decorated by local artists, and then set them up

不平衡

用had 是因為過去式囉！
不要把它誤認為是過去完成式喔～～～因為中間有個them 所以可以知道是個使役動詞，had them decorated by ～
就像是剪頭毛…會說：　have one's hair cut　（這裡的cut就是　被動　形式，不是名詞喔！）

因此平行結構如下：
commissioned..........., had........and set ..........

ｂ錯在　they 多餘　而且　3個句子裡頭只有一個連接詞！！ so....
