However, to prevent there being two answers for the final category I've reworded the 4th clue to remove Tbilisi as a possibility.
Tbilisi fits all descriptions.
Edit: Okay, due to countries and capitals being possible, I think this is the clearest and most accurate explanation now. "... which is landlocked and whose country/capital is"
So perhaps technically not incorrect, but not clear. I ll see if I can find a way to rephrase it so it flows better, (so you instantly get it and not as something you ll have to untangle first ;))
But please dont be discouraged from making these, :) one of my favourite types
Might not be perfect but atleast it is clear and cant be totally misunderstood.
I could not get the Singapore quiz, so I paused while I ate my tea. It suddenly sprung to me: SINGAPORE!

You could otherwise write "Has Star(s) on them". That would avoid confusions.
Has a star is perfectly fine. Now if it said has one star, I would tend to agree (though technically still true, it is not what it implies and would be like : "which month has 28 days. All of them" which is technically true, but not what is implied and just people trying to be a smartass imo)
