| Another way to do it is to ask for the city with the largest metro system in each country. Largest could be ridership, length, or number of stations. I'm afraid Wuppertal is destined always to bring up the rear of the most guessed list. Following my suggestion, New York would be the answer for the US, Berlin for Germany, Seoul for South Korea, Brussels for Belgium, etc. If you switch to this scheme I think the time is OK, if you keep the current scheme I think it should be extended a little. |
