making question sentence by using "COULD" (as past ability)


Stone age man could only sleep in the dark at night because there was no sunlight.

I think, "could" is used to express past ability, in above sentence.


Is it correct when I make question sentence from above sentence, like this:

What could stone age man do in the dark without sunlight, other than just sleeping?
