There's a different way to do the same thing, but the game shows it's wrong.

plate apple:only-child, pickle:only-child - does not work

plate pickle:only-child, apple:only-child - works

@LibeerDev the actual answer for the given question is: plate :only-child which is the simplest way to find plate's only child & it works fine as well.
It selects element that is the only element inside of the plate.
