I would think "世界有什麼有名的地方？" ("The world has what famous places?") would also be accepted. ("世界有名的地方有什麼？" is "There are what world‐famous places?")
世界有什么有名的地方 was just accepted in the "word bank" module, 2018年6月15日
That is my solution but it was not accepted.
And the given solution is not even correct!
Why is 世界有名的地方是什么 not correct?
