「東はどちらですか/ひがしはどちらですか」 should be accepted. どちら is more formal than どっち. Reported on Oct. 28, 2017.
If "east" and "which" are swappped, isn't that still correct?
You can't use the topic particle は with question words such as どっち or なに. So simply swapping 東 and どっち without making any other changes to the sentence would definitely be incorrect. ^^
I was given both どちら and どっち as options, and the former was marked incorrect. It should also be correct, right?
What is the difference between docchi, and dochira?
