34 To ensure consistently high quality in its merchandise,the chain of retail stores became involved in every aspect of their supplier's operations,dictating not only the number  of stitches and the width of the hem in every gament as well as the profit margins of those suppliers.

C.their supplier's operations,dictating not only the number  of stitches and the width of the hem in every gament but also

D.its supplier's operations,dictating not only the number  of stitches and the width of the hem in every gament but also

答案选D

书上说：the chain of retail stores 的核心词是the chain ，表示单数概念.

但是我觉得代词的逻辑意思不合理。应该是the retail stores的supplier，而不是the chain的supplier阿。

茫然中……

我注意到了这个its了。

哦，我知道我错在哪了．把chain理解成供应链而不是作为商品的链条了．汗～

这么说就懂了．

谢谢楼上那位．

是的，supply chain,供应链，逻辑很好！
