Randomize based on slider value

I have 8 elements in my slider question, each of which need to be rated on a scale of 1 to 100 (let's say the elements are called A, B, C, D, E, F, G, H). Imagine a participant rates A, F, and H below 25 (this is what I'm interested in). For each element A, F, and H there is an associated follow-up question. I want to _randomly_ assign the follow up question for A, F, _or_ H (one question) to the participant. In essence this boils down to: IF 1 one or more elements are rated BELOW 25, assign associated follow up question RANDOMLY from all elements rated below 25. I tried to do this with if branches, then randomization. However, there are so many possible combinations of ratings (a participant could rate all elements below 25, or just A and E, or A, E and H, or A, E, G, and H, etcetera). I was wondering if there is an easier way to do this, for example associating a follow-up question block with a slider element IF it is rated below 25, and randomly choosing which (out of all slider elements rated below 25) to present. I only need to present one. Hope this makes sense, sorry if it is unclear!
