Select from each of the following pairs of Lewis structures the one that is likely to make the dominant contribution to a resonance hybrid. Explain your selection.

Unfortunately, I can't include the structures, but I'm confused about the answers given in the book. Can you explain the resonance hybrid theory in this context?

You want the formal charges as close to 0 as possible on all of the atoms. Once you have that, you can switch the bonds around, while still keeping the same formal charges, to find the resonance structures which you would then use for the resonance hybrid.
