A．They taught the Mesopotamians about square numbers.
B．They were less advanced in mathematics than the Mesopotamians.
C．They did not use square numbers.
D．They knew how to measure angles.
参考答案D
解析: What does the professor imply about the ancient Greeks?
推断题。根据Because we discovered that Mesopotamians didn ’t know how to measure angles，which is acrucial element in the whole process of triangle calculations．和In all likelihood. it was the ancient Greeks who first calculate the link of triangle’s sides using square numbers．And this was hundreds of years after the Mesopotamians可知。三角形运算过程的关键因素是要知道如何量角，古希腊人十分有可能是第一个运用平方数计算三角形边长关系的，由此推断古希腊人知道如何量角。因此，正确答案是D。
