I don’t think it easy, even if we work hard, the South Korea and the North Korea to sit down to talk at present.
A. persuaded
B. to persuade
C. persuade
D. persuading

A. persuaded(答案→)B. to persuadeC. persuadeD. persuading解析：考查非谓语动词。两个逗号之间的部分是插入语，做题时可以忽略插入语，think/find it+形容词+to do sth认为......怎么样，it是形式主语，真正的主语是动词不定式。句意：现在，即使我们努力做工作，我认为也很难劝说韩国和朝鲜坐下来谈判。故选B。

哦，回答的不错
