Are both of these two sentences correct?
I think the usage of an article could be possible in front of an uncountable noun, while the abstract uncountable noun is more specified by an adjective.
But, I've never seen this method used before words like research, evidence, information etc. So I'm confused with my shabby knowledge on the word "construction."
How about the usage of an article in front of "shoddy construction"?
