The <noun> of <noun> [closed]
Solution 1:
The first noun in the [noun] of [noun] unit is treated as any other noun as regards modifiers, so (barring special cases such as idioms) wherever you would say the [noun1], you can also say the [noun1] of [noun2], etc.
As a corollary, it is also correct to use [noun1] of [noun2] without a the, especially if the wouldn't normally appear before [noun1] alone. Examples:
I drink a cup of coffee every morning.
Strength of will is important in a leader.
