问题补充：

the old man’s sons wanted to know was the gold had been hidden.

A. What; where

B. That; what

C. What; that

D. That; which

答案：

(答案→)A. What; where

B. That; what

C. What; that

D. That; which

解析：考查名词性从句。What引导主语从句what the old man’s sons wanted to know在句中做know的宾语。Where引导表语从句where the gold had been hidden指埋黄金的地方。句意：老人的儿子想知道的是黄金被埋的地方。故A正确。
