求翻译。这句英语中亮个that是怎么用的？均表示什么意思，详细帮分析一下句型,结构主谓宾补定状都是怎么划

Question

Is it an inescapable fact that the older you get ,the less you remember ?Well sort of.But as time goes by,we tend to blame
age for problems that are not necessarily age related.

Answer 1

你好。
第一个是同位语从句的连接词
第二个是定语从句的连接词，也是这个从句部分的主语

Answer 2

Is it an inescapable fact 【that the older you get ,the less you remember这个that引导的是同位语从句，就是fact的内容 】?这句话中it是形式主语，真正的主语就是that引导的从句。
Well sort of.But as time goes by,we tend to blame
age for problems 【that are not necessarily age related这个that是引导定语从句，用来修饰problem的】.这句话tend to blame是谓语 age是宾语 for后面的是状语
