问题补充：

you can say about London People for sure is they talk a lot about weather.

A. Which; what

B. What; that

C. That; what

D. What; which

答案：

A. Which; what

(答案→)B. What; that

C. That; what

D. What; which

解析：考察名词性从句。What引导主语从句what you can say about London People for sure，并在句中作主语。第二孔的that引导表语从句，that起连接作用，没有任何意义。句意：关于伦敦人你能说的确定的事情是他们谈论天气很多。
