关于名词性从句和定语从句,都是我有困惑的题目.

A that B which C where D what （我选A,为什么答案是C?）

3.It is in this very village,①__Mary was born 35 years ago,②__she will build her first school,③__inspires everyone to help her.
答案是where ,that,which（请问这三个空格都带着3个从句么?我认为①是同位语从句,②是③的主句么?③是定语从句.）
4.Mary is the only one of those ladies___bridge well.
A who B who plays C that play D which plays
（我糊涂了,在定从中先行词被the only修饰时不是只能用that吗?所以我觉得答案应该是that plays)

A in which B at which C by which Dfrom which
(为什么C不可以呢?）
6.The poor young man is ready to accept___help he can get,

答案是whatever.（天哪我真的被whatever和whichever搞晕了）
12.You can watch _没有范围的,表示任何一个_program you like .You are no longer a child .
答案是whatever.（老问题）
再问： 请问为什么第1题不可以是同位语从句呢？而且我觉得第4题答案不是who plays而是that plays.
再答： 你好。第一道不是同位语从句，是定于从句。 第四道：如果用了that play,就等于修饰后面的复数名词，如果是that plays就对了。
