About the "difference"
I need to know which one is correct as below:
1) There are many differences between.......
2) There is not much difference between....
3) There is much difference between.... ( or maybe it is better with " so much difference")
The word "difference" is a countable noun as well as uncountable noun, right?
I also have problem to define which is countable noun and which is not... how to figure them out?
