Hello,

I am creating a survey with several levels of randomness, but I want to show the participant the same question later in the survey to validate their sample.

In the survey, the participant is randomly presented 10 out of 20 blocks, and in each block, 1 out of 10 possible questions is randomly presented. (they answer 10 questions in total) I want to have an 11th question, where the user must answer 1 of the previous questions again.

Ideally, this 11th question would be randomly placed within the original 10 questions, but it is acceptable if it is just an extra 11th question.

Is there a way to do this in Qualtrics? (Also, I am just using the free trial account, without the full feature set)
