Please specify your methodology and source. And does this relate to total GDP? GDP per capital? Nominal or PPP? All of Europe or only EU?
I also see clear inaccuracies. If Paris and Madrid are so high I imagine this is due to total GDP, which is fine. But how come cities such as Dortmund or Stuttgart are higher than Frankfurt? There are many other examples. So please try to stick to one reliable source without contradicting information.
I believe that with this feedback, you have the potential to make this a great quiz. Thanks for your time.

Otherwise, Frankfurt would be higher, Lyon above Marseille etc
