Perhaps, rather than using a validation condition, under Look & Feel you could set Questions per Page to be 1. That would be easiest, I would think.
I've done this where in one question, I put the code: [a href="#money">More >></a] and then the Money question has [a name="money"></a] in its code. (Just replace the [ and ] with < and >.) The two questions have to show on the same page to work. The More >> link then moves the survey to the Money question/text/info.
I've done something similar, but put all the questions in the same block. I then used Block Options > Question Randomization > Randomize the order of all questions. Then, for each question, I did Choice Randomization > Advanced Randomization and set up advanced randomization. (I had 106 choices.) I then set up Custom Validation so that users would have to meet some condition before moving onto next page, which functionally only shows one question per page. I specifically designed this for mobile, so it might work for you.
I created an "app" to help teacher candidates prepare for the Foundations of Reading Test. Students can "install" it on their phones, and then study on the go! See Get the App! > our FoRT 'app' at: http://uwm.edu/education/academics/resources/foundations-of-reading-test-fort
