Croatia, question by question

Slovenia is a wrong choice for Zagreb and again for Croatia's flag and outline. Slovakia, Serbia and Slovenia sit beside Croatia in the flag round. For the outline, the other choices are Serbia, Bosnia and Herzegovina and Slovenia. Serbia and Slovenia are on both lists.

Trivia asks: “Which country joined the EU most recently?” The answer is Croatia. It also asks: “Which currency did Croatia use before it switched to the euro in 2023?” (Kuna). Korčula and Plitvice Lakes National Park, two of 20 Croatia photos, are marked easy; Ugljan is marked hard.
