......does it take to

I would say your guess is pretty good.

Take here means Requires. How many of them are required to physically change the light bulb.

Although it's a joke, of course, because I'm sure they'd have a whole lot of discourse first on whether the lightbulb was considered to be out, how they feel about it being out, should it be replaced, how they feel about replacing it... do any of them have any issues with darkness that they want to discuss, etc etc... and in the end they'd just call a janitor to change it.

Thank you very much!

"It takes how many councelors to change a light bulb."

This version is still a question and requires a question mark. In fact, this is sentence structure makes the question even more emphatic.

Here is my attempt to make the sentence into a declarative statement:

"It takes counselors to change a light bulb." Even more basic might be, "the light bulb needs changing."

Why don't they simply switch to natural candles and eliminate the light bulb issue entirely? This would be better for the environment as well.

It's very helpful indeed. Thank you Asherman!

And thank you NickFun, a candal party is a good idea for those counsellors!
