Under which condition can you hold your breath longer?

First breathe in as much as you can and hold your breath, and time it. (Lungs completely inflated)

After, breathe out as much as you can, hold your breath, and time it. (Maximal expiration).

Which condition can you hold your breath longer? Why?

I'm trying to relate all of this with chemoreceptors for carbon dioxide and oxygen. I would really appreciate a useful resource.

Hint: After breathing air, there is still a sufficiently high ration of oxygen in it in order to breathe it two times again.

That makes sense, that there is enough oxygen to supply the body for a longer time, however, I thought the body senses CO2 more, so after maximal exhalation, the CO2 decreases in blood, and you can hold your breath longer?
