正确答案应为A， 我错选成C,请教C 为何不对？

OG 11^th，36

 King Henry have his marriage annulled so as to marry Anne ,(does not identify who will marry Anne)  应改为  (So that he could marry )

问题：这里C 为什么不对啊 ，根据og中一题， C 中 把distinguished 保留动词，增加了文中的否定含义，应保留，

问题：这里C 为什么不对啊 ，根据og中一题， C 中 把distinguished 保留动词，增加了文中的否定含义，应保留，

如OG11TH 中 8题 rising inventories ,when unaccompanied correspongdinly by increases in sales, can lead to ...划线部分应为

（if not accompanied by corresponding increases in sales, can lead）

og中解答中写道；  unaccompanied  is not wrong but not accompanied puts greater emphasis on the negative , better

请高手解答,谢谢

OG10提问总结

OG11th对比OG10th新增题目讨论汇总

they are unable to be disinguished 逻辑意思不对。unable表示能力，不表示可能性，于是就变成了 shifts are unable to be disinguished. 原文要表达的意思是不可被辨认。

另外，这里用so as to 没有问题，因为不是双重宾语，不存在so as to短语逻辑主语的歧义。
