Hello Everyone,

I would like to know if is possibile obligate someone to answer at only one question in a group of items.

I have a group which contains 10 items and I need to oblige people to answer at only one of these questions.
So they can not answer to more questions and the can not go ahed without answering to at least one.

I know that is possible put the obligation inside on one question's answer but I don't know how to that in a group.


thank you in advance.

I give an example, look at the picture.

there are 4 options but what I need is only one answer because one exclude the others.
So I need that subjects are oblige to answer at only one of these options.

How can I do that?

Help me please!

I would put in a preceding question "What option would you like to answer? and then use relevance to show the appropriate question.

Thank you so much!

How does relevance works?
