Our team has prepared five technical reports that we are going to present to a review committee tomorrow. Each report is very long (about 20 pages). I want to communicate to my colleagues that we should prepare a one-liner description for each report. Here are the two alternative sentences I have.
I need one-liner descriptions for all five reports we are going to present tomorrow.
I need one-liner description for all five reports we are going to present tomorrow.
The difference in the two alternatives is the usage of the word "descriptions" vs. "description". Is singular-form the right choice for a sentence like this, or should I use the plural-form?
Note: The above specific scenario and sentence is a scenario I have cooked up to demonstrate my problem. I am interested to understand the singular vs. plural not just for this sentence but in general for any sentences like these which contain a phrase of the form "<noun1> of <noun2>" where "<noun2>" is plural and I need to decide if "<noun1>" should be written in singular or plural form?
