The Sponge Equilibrium Question

This is a simple question. What is the moisture content of the two sponges at equilibrium? Please think about your answer carefully, before moving forward.

Basically, we want a room temperature closed box that has an inch of pure water at the bottom. We then hang a wet sponge and a dry sponge in the box and wait until they reach equilibrium. There aren't any details that are hidden, there are no tricks here. Just an honest box with a couple of sponges. We could have used one sponge of any saturation level, but I think that two sponges helps to visualize the outcome. Let's specify the details:

Three possibilites: Pick your answer.

What will the final moisture content of these two sponges be at equilibrium?
