Answer 1

The rising popularity of belly dancing is evidence of turkey's growing cosmopolitanism.

Answer 2

The correct answer is belly dancing.
Turkey is becoming more and more cosmopolitan as time goes by, which means that it is becoming more global. People are starting to like some things that are inherently of Turkish origin, such as belly dancing - this type of dancing didn't use to exist in the West, but now it does, thanks to Turkey.
