acknowledge one's debt to的意思？

Question

翻译一下：
He is always ready to acknowledge his debt to his teacher.
别用机器翻啊，应该是acknowledge有致谢的意思，但这个debt?不是债务么？
但是，这样是解释不通的啊。
没有上下文，这是选择题。
A.thank B.acknowledge
主要就是从这两个选项去选，答案也是B.根据类似的题目推知这里考的acknowledge大概就是thank的意思，但具体两者区别在哪，为何要选acknowledge?

Answer 1

acknowledge在这里应该是“承认”的意思，debt也可以表示“所欠的东西”，不单单指债务，联系上下文会比较好理解。be ready to do可以是“乐于做某事”的意思

Answer 2

acknowledge one's debt to one's teacher
