求解大全I－1究竟选B还是D？？

A mail order company recently had a big jump in clothing sales after hiring a copywriter and a graphic artist to give its clothing catalog a magazinelike format designed to appeal to a more upscale clientele. The company is now planning to launch a housewares catalog using the same concept.

The company’s plan assumes that

(A) other housewares catalogs with magazinelike formats do not already exist

(B) an upscale clientele would be interested in a housewares catalog

(C) the same copywriter and graphic artist could be employed for both the clothing and housewares catalogs

(D) a magazinelike format requires a copywriter and a graphic artist（B）

(E) customers to whom the old clothing catalog appealed would continue to make purchases from catalogs with the new format

第一次做的时候选了B，结果补充材料的答案选D，听NN解释了之后终于认可了D，今天再做大全，发现答案竟为B，也有NN说应该选B，究竟选什么？？有没有比较统一的答案？？

B

雇了几个人－－出了一本书－－吸引高消费人群－－销量上升

现在：准备出另一本书，使用相通的概念目的是吸引高消费人群，销量上升

B：富人喜欢将要出的东西

如果富人对houseware没兴趣

这样的方式不赚钱。

D:人已经雇了，D没什么意义了

谢谢

hahaha, very interesting explanation, and very good!
