Hello,

I am using Moodle version 3+ (I do not know the exact version as it is hidden) and I would like to create a multiple-choice question using the Formulas plugin (I do not have many available unfortunately). Depending on the chosen answer, I would like the students to fill an answer box, for example: what is the domain of function \(f\) ?

- option A: all reals numbers.
- option B: all real numbers except "answer box" (students have to fill it)
- option C: all real numbers except "answer box 1" and "answer box 2" (students have to fill them both)

Do you know how I could do that ? I want them to choose an option first and then fill the answer boxes accordingly. So if they choose option A, they do not have to fill any box, if they choose option B, they have to fill the corresponding box (and only this one) and finally, if they choose option C, they have to fill the two corresponding boxes.

Thank you !
