问题补充：

The number of the people invited to the meeting about 100, but a number of them late because of the heavy snow.

A. were; was

B. were; were

C. was; were

D. was; was

答案：

A. were; was

B. were; were

(答案→)C. was; were

D. was; was

解析：考查主谓一致，a number of+可数名词复数，表示“很多“，后面的谓语是复数，the number of+可数名词复数，表示“…的数量”后面的谓语是单数，所以第一空填was第二空填were，，句意：被邀请参加会议的人的数量是100人，但很多人因为大雪迟到了。
