Answer: variable; fixed
Explanation: In the short run, Kyoko's workers are variable inputs. This is because, the number of workers needed can be varied based on production needs, even in the short run. Examples are energy, labor etc.
Kyoko's ovens are fixed inputs. Fixed inputs are those inputs whose quantities cannot be changed in the short run by a firm as it seeks to change the quantity of output produced. Examples are equipment, land and building.
