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.

Hi, Neil,

Unfortunately, the system can't tell that either instance of "decrease" should be acceptable for items b & c. 

I suggest you use a multiple choice/response question instead. Either do a single-response question that asks which of the following should be increased, or do a multiple-response question that asks which of the following should be decreased.

Another option would be to create a freeform question that includes 2 radio buttons (Increase and Decrease) for each of the options. (In essence, that'd be a type of multiple-response question. It'd just look different than the built-in versions.)
