Hi, anybody wants to play a pop quiz?
The rules are simple, you take the hot seat. You answer my questions. If you get five right ones in a row, you get to ask the questions. If you are wrong, you let someone else take the hot seat.
Anybody game?

I'll do it.

The first question is:

Which country hasn't a single woman living in it?

Hints?

Would that be a country with no women in it or a country where all women have boyfriends/husbands?

A country, where no women are permenantly living.

The Vatican?

(I know there are nuns living there but there might be some strange law about them)

That is correct.
The Vatican has the population of 1000, no more no less, and only these 1000 people are officially residing in Vatican and they are all males.

Congratulations.

Which is the only men-made object, that can be visable from sapce?

How far away (space is very vague)?

If the answer you want is The Great Wall of China then you can't actually see that because it is too thin.
