Prompt

Make a capital cities quiz. Show me country shown, name the capital, covering all of them. Make it a single HTML file that opens in a browser with nothing to install and no other files. Put the CSS and JavaScript inside it. Do not use image files or any external address; use emoji or letters if you need a symbol.

Put the country and capital pairs directly in the code — about sixty of them. Do not fetch data from anywhere.

Give four choices per question. Take the wrong ones from the same region, so the quiz is about knowing rather than guessing by continent.

Keep score as I go. At the end, list what I missed with the right answers so the quiz is also a study sheet.

When you are done, check that the wrong choices really come from the same region as the answer.
