This probably has been asked before but I don't know exactly what good keywords are to search for an answer. I wonder if the plural form has to follow a list of descriptors.
Given the following sentences:
A) You will find screws in the red, green, and blue boxes.
B) You will find screws in the red, green, and blue box.
I tend to think that A) is the valid form because we talk about several boxes here, one red, one green, one blue. However, how would we know that there are not multiple red boxes? Equally confusing - would B) mean that there is one box, and it is red, green, and blue? Or is B) simply an invalid construct?
I am specifically interested in lists connected with "and". For "or", I found this thread which is imho reasonably answered.
Thank you for taking the time to read this.
