Hi everyone I'm just a beginner so sorry for my bad english. I bumped into a question on instagram onto a page created for people who want to improve their english skills. The question was " All the lights in the building suddenly went...? A) off B) out C) down " The correct answer was A but I didn't get it. So I was just wondering what is the difference between went out went off and went down. Thank you if you answer.
Lights go off when people (or timers) make that happen using a switch.
Lights go out when there is a power failure or other accident.
Lights go down when they dim. That happens in a theater when the play is about to start.
To me, in your question, the "suddenly" suggests a power failure. The lights went out. I would choose (B).
