Quesion? What criteria trigger a Golden Age?

[Hellion]

Hello,

I've scoured the FAQ and all over, but can't seem to find the answer
to this question. Hopefully someone can point me in the right direction.

I read:
>The game checks the qualifications for a golden age everytime you build a
>wonder (any wonder). If you already control (by capture or culture flips)
>wonders you didn't build, but meets the criteria for your golden age, then
>the next wonder you build will trigger a golden age.

So, what are the criteria that need to be in place to trigger a golden age?

Thanks in advance.

For this example, the criteria are you need to control any wonder or combination of wonders that have the same traits as you. You can also win a battle with your UU.

The wonder GA is that you have to control wonders that fit your traits and build any wonder.
