There are potentially two ways to approach this 25% requirement:
If there's no strict need for randomization of stimuli, then perhaps the easiest way is to use the catch trial feature (https://help.findingfive.com/api/procedu...tch_trials). The downsize is that it will introduce a pattern: a comprehension question pops up every X stimuli.
Alternatively, a hacky way to do it is to tweak the trial template that generates your comprehension question trials so that 75% of them actually a blank trial (or a sentence saying "this screen is intentionally left blank" or something like that). Then when you yoked everything together, it'll seem like only 25% of them have a comprehension question.
