Can you make sure ___________? A. that he will come here today B. when he will come here today请教高人请问此题选什么，为什么？请具体解释一下

Answer 1

Can you make sure…… 你能确定 ……选A. that he will come here today？
你能肯定他今天会来这里吗？因为是make sure所以后面用that。 如果想要问 ‘你肯定他今天什么时候来这里吗？’应该是are you sure when he will come here today?

Answer 2

选A。因为这是一句宾语从句，意思是你能确信今天他会来这？
