Our eating habits have changed,___our way of life ,and the fuel we need for our bodies is also different.
A:so is
B:so has
C:which was
D:the same is
为什么选b 啊？其他的不对吗？

Answer 1

Our eating habits have changed,___our way of life...
此处所要表达的是Our eating habits have changed, our way of life has changed too.
表达后者也适用于前者情况，用so + 助动词/ 情态动词/be动词+ 主语，即：so has our way of life.

Answer 2

我们的饮食习惯改变了，生活方式也改变了
这里的也 可用so +do（did/is/have/has）的结构表示，由于该词组的主语是our way of life ，所以用第三人称单数，而前面的语句中用得是have，所以用has
如果用D 应该是the same as

Answer 3

so is it 的倒装形式意思是"...也是这样"
这里用so has 是因为前一句我们的饮食习惯已经发生了变化，用的是完成时态，所以为了保持时态一致性，应该选B：so has "我们的生活方式也是如此"
