A door related question

[Blue Ranger]

Ok earlier I wanted to sign up for this other forum that's for students with questions, but they require you to give all your information before you join, including your blood type, height, money in the bank.

Anyway, a student asked this question "Dear teachers,
Can you tell me if this sentence is right?
Do somebody go to close the door?"

A teacher replied with this answer "No, it is not right. You could ask someone to close the door and say,
"Could somebody go close the door?" or "Would somebody close the door?" or "Could somebody go and close the door?"

You could also ask if it has already been done. "Did somebody close the door?" "Did somebody go and close the door?" "Did somebody go (in order)to close the door?" might be okay too, but I would prefer the other two, myself."

Now what I want to say is this, what is wrong with "Does somebody close the door?"

Example:

Person A: Does somebody close the door?
Person B: No because this is a sealed room, if the door is closed we will die from lack of oxygen.

"Does somebody close the door?" is correct English but its tense makes its use quite limited. It doesn't really seem to work in your example. These would work:

A: In that scene in <some movie>, does somebody close the door?
B: No, because then they would all die from lack of oxygen.

A: When we have a fire drill, does somebody close the door?
B: Yes, the fire marshal always does that.
