I was going to comment the same. Also, "basílica" instead of "basilica". I know I'm splitting hairs though, these are just minor details on an otherwise great quiz!
I got three the first time I took it. Today, I was able to up that to 4/10. Still worth zero points, though. This one just seems much harder than the other city quizzes.
Short, ten questions including picture type Ques, mcq format. 🫡
Easter egg with my home city (not that far from Barcelona) in the picture question. ;-)
A little observation would be that in Catalan, so more official, would be "Avinguda Diagonal".
