First to answer your last question first. A TYPEO on my part, I used answer instead of question. I will go back and edit to correct the post. Thank you for pointing that error out. Sorry to have confused you.

I can see the confusion. You have to have an understanding of SQL (Sequential Query Logic)
SQL is much much faster. It is too complicated a subject to explain here. It would require a thread of it's own.
Go to W3Schools and read up on SQL.
Wordpress is based on MySql. One of the reasons if you choose the right theme, Wordpress is so fast.
Each question is stored in a database and the record id is used as an index to locate the answers(s) to display.
A page designed this way would be unique for the most part about 99 percent of the time, but that would be dependent on the questions asked and the answers displayed.
Not trying to be short, but it really is a complicated subject to discuss if you have no understanding of SQL.
