问题补充：

—Is there any possibility you could pick me up at the airport?

—No problem.

A. when

B. whether

C. that

D. what

答案：

A. when

B. whether

(答案→)C. that

D. what

解析：考查同位语从句的用法。that引导同位语从句解释说明possibility的内容。句意：--你有没有可能到机场接我？--没问题。When连接同位语从句，一般同位词是question这样的单词，what在从句中做主语宾语或表语，但是这句话不缺成分，whether是否，不符合句意，选C。
