This is inspired by the post about multiple choice tests . I was a nuke in the Navy (Nuclear operator….reactor plants, not weapons). The training was extensive, and there wasn’t a multiple choice test in the entire program. You were graded on knowledge, not trivia. (You got more points for explaining the right answer, without knowing the actual terminology, then just writing down the right answer.)
Anyhow, here is a question I used to ask people that came to me to qualify for a few of the watches (jobs) in the plant. I’ll preface this by saying that the engine room in question supplies all utilities of the ship, from propulsion to fresh water.
Where is the only incandescent lightbulb in the entire plant, and why?
Enjoy!
