Matching Drop-Down Question

Hi Richard and welcome to the community!

I'm afraid it's not possible to filter out duplicate responses for this type of question. You could be more specific in some answers, however, and that may help with the selection and also help avoid confusion. 

For example, for "San Francisco" you could have "Northern USA" and for "San Diego" you could have "Southern USA", etc. 

Another option would be to use a different type of quiz question. For example, you could create a freeform drag and drop quiz with multiple answers landing on the same location. 

I made a very quick drag-and-drop example using Quizmaker '13, if you'd like to check it out:

Example for Richard

You could even get a little more creative and use shapes that are similar to the countries, or you could create labels for the states and drop those on the city names. 

I know that's not what you were looking for, but I hope it helps! I'd love to hear some additional suggestions, as well.

Thanks and good luck with the project!

Great, thank you Christine - this definitely gives me some ideas of how to approach this quiz question!  Thanks for creating the example as well - much appreciated!

Excellent! :) Happy to hear that, Richard.

I'd love to hear about your project, if you get time to share an update when it's finished. 

Have a great day!

Christine
