I found a sentence on an online English test.
Question: More money is now spent on fuel than before.
Answer: Not as much money was spent on fuel before as now.
I have learnt "comparative structure like "as adjective as ", "adjective than." I found as adj as, as much/many noun as. But I did not know which structures are those sentences? I really want to know this structre "not as adj noun v as noun "
