Amsterdam has launched a quiz to encourage people to stay away from the city's notorious red light district. The city has also introduced a ban on the use of drugs in public places.

It remains to be seen whether the quiz will have a positive impact on public opinion. The quiz is available in English, with versions in French, Italian and Spanish. It is also available in Spanish, with a Spanish version to be released later this year. For more information on the quiz, visit: http://www.justgiving.com/Amsterdam- quiz.
