A
在那个学校发生了巨大的变化,不再是20年的样子了,那时配备的很差.
考查两个从句,一个是名词性从句.一个是非限制性定语从句.
名词性从句缺成分,要用WHAT 它20年前是什么样,这个什么要用what充当.
后面有逗号,肯定是非限制定语从句,后面句子不缺主语宾语这种成分,那么就是选择一个关系副词,先行词就是20年前,那个时候管理配备的差.
你问的几道题,我都作答了,你看一下答案,明白不?不明白的话可以和我联系.

选C
第一空what做表语从句的(was的)表语,what引导的从句做is的表语
第二空这个分句缺少状语20 years,which来指代,不用when,因为when指代的是at/... which

what在这里表示the school that,
when 在非限制性定语从句中充当时间状语,故用关系副词when

那所学校已经发生了巨大的变化。它已经不再是20年前那样了,那时设备室那样的差。
第一个空为what连接的名词从句做表语,“学校再也不是二十年前的样子了”;第二个空为when引导的非限定性定语从句,指代“二十年前”.
希望可以帮到你
