谢谢 ,这个解释可以理解为什么不选d 了。。但是 og vb 16 又解释这个选项:This sentence is a little awkward (the article a in a part is unnecessary) and says something rather different; as a part of a deal to make suggests that the deal itself includes making the company the largest manufacturer rather than its being the outcome of the deal.又晕了。。
