Great vs great

[lycongvinhto]

Hi teachers,
I have a trouble in using the word "great". It seems that "a" usually precedes "great" in most sentences. For ex:
The earliest steam-driven vehicles produced (great)/ (a great) amount of noise.
Is there any difference between two choices? what case should we use "a great" or "great"
Thank you so much.
Best wish.

It has nothing to do with "great". In this case, it's "amount". They produced an amount of noise.
They could have produced a small amount, a large amount, a negligible amount, or really any amount at all. But you still have to use an article before a noun, even if it has an adjective before it.
