Making a nice home and securing a good future for your famil

Making a nice home and securing a good future for your family is _____as pursuing any career success.
A.a mission as much B.as much a mission C.as a much mission D.much a mission
答：B
译：为家人营造一个安逸的家与追求事业的成功同等重要.
析：根据语法,同级比较as...as,排除D
根据语感,排除C.
根据逻辑,排除A：这个思维程如下：
1.我有很多书：I have many books.
2.我有多达1000本的书：I have books as many as 1000.
3.我有和彼得一样多的书：I have as many books as Peter (does/has).
4.这句话不能表达成：I have books as many as Peter.
同理：
1.我有很多水.I have much water.
2.我有多达10公斤的水.I have water as much as 10 kilograms.
3.我有和彼得一样多的水.I have as much water as Peter( does/has)
4.这句话也不能表达成：I have water as much as Peter.
再来分析与本题类似的句型：
Doing A is a mission.V
Doing B is also a mission.V
Doing A is as much a mission as doing B.V
Doing A is a mission as much as doing B.X
最后一句逻辑不对：as much as doing B.是以much为中心词的一个后置定语.既然mission在这里是一个可数名词单数,就不可能用much来修饰它:X Doing A is a much mission.
我们可以用形容词great来修饰它,且有两种说法：
Doing A is a great mission.
Doing A is a mission as great as doing B (is).
Doing A is as great a mission as doing B.
所以我认为这个题目的最佳答案是B不是A.
这一题可能在BA之间谁是最佳方面有争议.

B

答案是A，is前面是主语,a mission 是宾语，as much as 和。。。一样是宾语的同位语，修饰宾语的。

我也觉得是选择A

选B,C中much不能修饰名词，排除；A代入后翻译于原句意思不同，D中还没有as。

A

选A. 前面可以理解为： .... for your family is a mission 。。。是一个任务。 后面是修饰语：as much as.... 如同。。。一样
