问题补充：

of furniture have been tested to guarantee good quality.

A. A great deal of

B. A large number of

C. Large quantities

D. A good many

答案：

A. A great deal of

B. A large number of

(答案→)C. Large quantities

D. A good many

解析：本题考查“许多”的区别。furniture是不可数名词，不可用BD项修饰；A great deal of+不可数名词作主语谓语动词用单数；a quantity (of), (large) quantity of 作主语或修饰的名词作主语，其谓语动词应根据quantity 的单复数形式而定。
