______down, she bricks up the firebox as well, sealing the remaining heat inside. (A question from an ACT English test)
"Once the blaze dies" is the correct one to fill in the blank, which I can understand grammatically, but I still think the other option, With a blaze that dies, could also be fine. What's the nuance that makes the difference between these two options?
I want to know why "with a blaze that dies down" is not idiomatic? I think it is correct in terms of both syntax and semantics. Or simply I should learn it by merely memorizing such non-idiomatic error because that's how English speakers are used to say.
