单选题 Since the two countries couldn't ______ their differences, they decided to stop their negotiations.
A. rectify B. oblige C. reconcile D. obscure

【正确答案】 C

【答案解析】[解析] 四个选项的意思分别是：rectify改正；oblige满足请求；reconcile使协调，使一致；obscure使模糊不清。句意是，既然两国不能协调其观点分歧，他们决定停止谈判。所以正确答案是C选项，如：The children quarrel but soon reconcile．(孩子们吵架，但不久又言归于好。)
