Question

____ the problem was ______ he could deal with, he called the police for help.

A．To realize; what	B．Having realizing; more than
C．Realized; more than	D．Having been realized; what

Answer 1

B

意识到问题超出他所能处理的范围，他打电话向警察寻求帮助。more than超过；realize这一动作发生在主句谓语call之前，所以用realize的完成时，且realize和主语he是主谓关系，所以选B。
