Dynamic exclusion of previously seen items

Hello!

I would like some recommendations on an efficient and workable way to build a questionnaire with the following requirements:

1. I have a set of 20 resumes. 10 of them are high quality resumes, and 10 of them are low quality resumes.
2. I would like each participant to read a total of 4 resumes from the pool of 20 resumes, 2 high quality resumes and 2 low quality resumes
   • The resumes are randomly selected from the pool of high and low quality resumes respectively 
   • The order in which the participant sees the high and low quality resumes should be randomised
3. After reading each resume, the participant will respond to 3 questions. The 3 questions are always the same questions.

I am not sure how to do the following effectively and would need your insights on this:

• How to dynamically EXCLUDE a resume from the subsequent resume pools if the resume has already been shown to the participant previously?
• For example, within a session:
  • The participant has seen Resume #4 as the 1st resume. Resume #4 will thus be EXCLUDED from the pool of resumes that could potentially be shown to this participant for the subsequent resumes.
  • For the 2nd resume shown to the participant, Qualtrics will randomly select any resume EXCEPT Resume #4 to be shown to the participant. 
  • Let’s say that for the 2nd resume, Resume #10 was shown to the participant.
  • The logic would then follow that Resume #10 will thus be EXCLUDED from the pool of resumes that could potentially be shown to this participant for the subsequent resumes.

Thank you!
