问题补充：
The number of people invited to the wedding yesterday two hundred, but a small
number of them absent .
A. is ; are
B. was ; was
C. was ; were
D. are ; were
答案：
A. is ; are
B. was ; was
(答案→)C. was ; were
D. are ; were
解析：考查主谓一致。The number of…指…的数量。做主语时，谓语动词用单数，故第一空用单数；a number of 许多，修饰可数名词复数形式，做主语时，谓语动词用复数形式，故第二空用复数。句意：昨天被邀请来参加婚礼的人数是200，但是很多人都缺席了，根据yesterday说明使用过去时，故C正确。
