How does grammar tell me to parse this sentence:
Visualize the relation between two-dimensional and three-dimensional objects.
Are we being asked to visualize the relation between two-dimensional objects and also visualize the relation between three-dimensional objects (each dimension on its own)?
Or, are we being asked to visualize the relation between an object in the two-dimensional group and one in the three-dimensional group?
I think what's confusing me is the interaction between the plural objects and and. So, my question essentially is how to understand this sentence and similar ones having the same construct. Is there a grammatical rule?
