Using drop down question types
I am having difficulty with a question type which uses drop down options for answers. If you have two answers that are identical how can the system differentiate between the right choices?
For instance, in a hypothetical question, the choices are:
a.) oxygen = increase
b.) nitrogen = decrease
c.) carbon dioxide = decrease
Currently when I test this the system reads each "decrease" answer as different. Thus c.) decrease cannot be selected for b.) answer option.
Hope this is clear.
