2b) "Success in business
requires a knowledge of human nature and an acceptable personality." => The indenifite article

requires a knowledge of how social classes act." => The indenifite article
My assumption is that in the first three sentences the word "knowledge" is not specified by any further details whereas in the three senteces (1b-3b), the word "knowledge" is referring to the words following it and therefore is specified and thus countable.Could anyone; however, try to offer me a better (or correct) explanation of this phenomenon?
I am much obliged to anyone for helping me.
