问题补充：

It was in the lab, was taken charge of by Professor Curie, they did the experiment.

A. where; that

B. that; that

C. which; that

D. which; where

答案：

A. where; that

B. that; that

(答案→)C. which; that

D. which; where

解析：第一空考查非限制性定语从句，先行词为the lab，从句中缺少主语，所以用which，第二空是强调句型，用that是强调句型的标志。句意：就是在由居里教授负责的实验室里，他们做得试验。所以选C。
