loveflora1229

The normative model of strategic decision-making suggests that executives examine a firm’s external environment and internal conditions, and in using the set of objective criteria they derive from these analyses, can decide on a strategy.
(A) conditions, and in using the set of objective criteria they derive fromthese analyses, can decide
(B) conditions, and they use the set of objective criteria derived from these analyses in deciding
(C) conditions and, in using the set of objective criteria derived from these analyses, deciding
(D) conditions and, using the set of objective criteria derived from these analyses, decide
(E) conditions and, in their use of the set of objective criteria they derive from these analyses, they decide

答案是选D，说examine与decide并列，那么我就不懂了，conditions后面为什么要加个and呢，假如是verb并列，为什么不是在decide前面加呢。我选了B,当作两个独立句子了（虽然按照ron神的说法答案中有不用pronoun就不用pronoun,但百思不得其解），谢谢坛子里各位NN观帖指导

这个中间的插入语可以忽略，没有任何问题

...that executives.......and they这里的they是多余的，前面已经有唯一的主语了，后面也不需要重复，简洁原则
