问题补充：

The owner of the cinema needed to make a lot of improvements and employ more people to keep it running, meant spending tens of thousands of pounds.

A. who

B. that

C. as

D. which

答案：

A. who

B. that

C. as

(答案→)D. which

解析：which在此引导非限制性定语从句。注意不能选B，因为that不用于引导非限制性定语从句; 也不能选A，因为who只用于人; 也不能选C，因为as引导非限制性定语从句时，它若用作从句的主语，则其谓语动词通常只能是连系动词。
