I've created a skills assessment test for the purpose of hiring maintenance technicians. The question below is one of the questions on my test. So far out of 10 candidates nobody has gotten it right. So now I'm doubting myself; maybe I'm not clear or maybe I'm just plain wrong. I don't want to divulge the answer just yet (I will later) because I don't want to set up any preconceptions that will alter anyone's thought processes as they try to work it out.
If you have nothing better to do, please answer the question and give a brief explanation of why you chose it.
