Question

【题目】The number of various educational programs is increasing, _______ important roles have been realized by more and more people.

A. whose B. where C. which D. that

Answer 1

【答案】A

【解析】

试题分析：分析句子结构可知逗号后是一个定语从句，修饰先行词programs，空缺处在该定语从句中作定语，修饰roles ，故用关系代词whose表示所属关系。句意：出现了越来越多的教育项目，越来越多的人已经意识到它们的重要作用。
