问题补充说明：The school board listened quietly as John read the demands that his followers____ for.A.demonstrate B.be demonstrating C. had demonstrared D.should demonstrated 请问正确答案是哪个，并且说明选择的原因，谢谢！
应选A，实际上是should demonstrate，should被省略了。that his followers ______ for是一个定语从句，修饰demands。demand的表语从句、同位语从句、定语从句以及作动词时的宾语从句中的谓语要用“should+动词往端原形”的形式，should可以省略。
