问题补充：

There was an oil painting in the corner. It there for several days.

A. laying; had laid

B. lain; had laid

C. lying; had lain

D. laid; had been lain

答案：

A. laying; had laid

B. lain; had laid

(答案→)C. lying; had lain

D. laid; had been lain

解析：考查分词做定语。第一空中的动词lie与an oil painting构成主动关系，故使用现在分词短语lying in the corner修饰an oil painting。第二空根据句意说明使用过去完成时，lie（位于，躺）是一个不规则动词，过去式和过去分词为(lay, lain)；故C正确。
