问题补充：

Every athlete as well as some coaches who to go to the Games asked to be here before 7:30 am.

A. are; are

B. is; is

C. are; is

D. is; are

答案：

A. are; are

B. is; is

(答案→)C. are; is

D. is; are

解析： 考查主谓一致。some coaches 是先行词，who to go to the Games是定语从句，定语从句的谓语动词要和先行词保持一致，所以要用复数are; as well as连接两个并列主语时，谓语动词和前一个主语保持一致， every athlete是句子主语，是单数，所以第二空用is。选C。
