选哪个，为什么

Answer 1

答案：C
解释：because

是复合介词，后接名词、代词或者名词性从句。这里接the
fact，that引导的是同位语从句，that不可以省略。

Answer 2

答案C

because of 后面必须接一个独立的名词the fact，that 就可以引导一个修饰fact的定语从句了。这样非常符合because of 这个短语的用法了。

Answer 3

这个不是that的问题，因为because
of后面是跟名词的，he
had
been
working
hard这个从句是修饰这个名词的，所以必须有这个名词出现。选3

Answer 4

C
that是fact的同位语从句

希望能帮到你，
如有疑问，可追问~

Answer 5

c.因为of是介词，后面要加名词，而空格后年又是一个句子，根据意思可以看出，是fact的同位语从句，同位语从句连接词只能用that,
