first greets all the faithful teachers hereQuestion (copied from my accounting exercise book):
Lana Emerick handles cash receipts and has the authority to write off accounts receivable. This violates
separation of (1)
A.
custody (2) of assets from accounting.
B. operations from accounting
C. duties within the accounting function
D.
authorization (3) of transactions from
custody (4) of related assets.
1. How come there's no 'the' before 'separation'? Since 'separation' is a countable noun, 'a' or 'the' must be used in front of it, or we'll have to use 'separation
s'. I thought 'of' makes 'separation' definite
2. How come there's no 'the' before custody? Ok 'custody' is not countable, so we use either 'the' or nothing before it. But in the case, I thought 'of' makes custody definite, so why didn't they use 'the'?
3. The same for 'authorization', it's countable, and 'of' makes it definite
4. Again the same for 'custody'.
My explanations for the four cases above are what I have leanred about articles. I thought any countable noun must be modified with an article or used in its plural form rather than preceded by nothing. ie. "the University of blah blah", "the city of blah blah." "a friend of mine"; on the other hand, I thought any noncountable noun must be preceded with 'the' if it's followed by 'of'.
However, the case above proved me wrong, and I think I must have got it wrong somewhere. (unless the person who wrote this question was trying to be lazy)

Teachers, please shed some light!
