Why do supervisors like to be asked questions?

Supervisors like to be asked questions for many reasons. Some like to know that their employee's are trying to learn more about their line of work and maybe even help that employee move up in position. Sometimes managers/supervisors like to be kept on their toes when asked something they are not sure of it helps everyone grow. Honestly that is the key role of a supervisor to find ways to make the operation move as smoothly as possible with as little hiccups along the way and your question may be the answer they were looking for. finally a question not asked is a question never answered.
