问题补充：
made her succeed later on was the kindness and consideration she showed to all her patients.
A. That; what
B. What; what
C. That; that
D. What; /
答案：
A. That; what
B. What; what
C. That; that
(答案→)D. What; /
解析： 考查主语从句和定语从句。 made her succeed later on是主语从句，且从句缺少主语，要用What; she showed to all her patients是定语从句，先行词是the kindness and consideration，在定语从句中作showed的宾语，要用that/which/省略。所以选D。
