Running down the good old road

0Hi,02br
02br
00Am I correct in laying out the following explanations?02br
02br
001. I got these two sentences from online sources like google and NY times.02br
02br
01i00Look no further Jeff has 01u00a superb coverage02u00 with insights from a VC perspective.02i02br
02br
01i00The BBC had 01u00superb coverage02u00 of the Soviet Crisis. 02i02br
02br
00Why, one has the article, whereas one doesn't? I think, eventhough, I don't fully get it is that, as Clive said in one of his responses, once you start to qualify it, it is OK to place 'a'.02br
02br
002. But if I was using the word like 'knowledge' or 'understanding', some more work is needed like this to make the situation OK for the placement of 'a', I think.02br
02br
01i00I have01u00 a great understanding02u00 of medieval history.02i02br
02br
01i00I have 01u00a great understanding02u00 of human nature.02i02br
02br
00See, now you need to add something behind like 'of medieval history' or 'human nature' and just an act of qualifying with the placement of the right kind of adjective wouldn't do.02br
02br
003. Now for the uncountable nouns like 'uneasiness', it is a different matter than the above two.02br
02br
00I think Clive used this sentence in one of his responses.02br
02br
01i00I had 01u00a lousy uneasiness02u00 in my mind this morning.02i02br
02br
00Now, even more effort is exerted to make the sentence somewhat distinguishable by type or degree. 02br
02br
00Now, my position is that it is the nature of the uncountable nouns that a person is using that determines the level of effort needed to make the transformation from countable to uncountable work?02br
02br
00Right? Wrong?02br
02br
00Sorry if my questions on articles are too boring. 0-
