谁能解释一下下面这个句子“as”的用法,as是引导一个同位语从句么?

We can't give answers to the question as the extent to which the sea and the coast affected human life in the past,what percentage of the population at any time lived within reach of the sea.
to which是引导一个定语从句么?the extent 是先行词?
上面的句子是我简化的（误删了“such”这个关键的单词）
原文是这样的
We are not yet in a position to make even preliminary estimates of answers to such fundamental questions as the extent to which the sea and the coast affected human life in the past,what percentage of the population at any time lived within reach of the sea，or whether human settlements in coastal environments showed a distinct character from those inland

去查了一下the extent to 发现它通常后面接which从句，比如：At issue is the extent to which exam results a student's ability.意为：考试结果能在多大程度上反映学生的能力是问题的关键焦点。the extent作表语，要反映的事情和程度之间用to链接。放到原句里，the extent 作宾语answer 的补足语，即the answer to the extent to which…（“回答…程度怎样”；而题主问的as在这里的用法，我个人认为，简化原文后出现such fundamental questions as…其实就跟such as 的用法是一样的，后面举例接名词，短语或句子，只是这个名词短语特殊了些还接了定语从句（the extent to which …）到这里应该解释得通了，句意为：我们仍无法对这样一类基本问题做出初步解释，比如过去大海与海岸在何等程度上影响了人类的生活,或者任意时期里沿海居民人口所占的比例是多少，再比如沿海居民与内陆居民是否表现出明显的性格差异。
