Conditional Randomization based on previously randomized question (whichever wasn't picked)

How do I pick a question at random from a group of questions and then afterwards ask another question from the same group that excludes whichever questions was already asked?

Would they be one right after another in the survey? Then you could put them in a block together and use the randomizer to randomly pick a question without repeating. If you want this to be a bank of 10 and only ask 2 that's doable by putting them all in the same block and using advanced randomization to display a random subset.
Technically no, since there are a series of questions (also randomized) that they need to see after each of the questions.

To be specific, I have 16 images total.
1a-h and 2a-h. A participant should be randomly exposed to any one of those images (say 1b), then given 5 questions in random order, then exposed to the corresponding image in the 2 category (in this case 2b), then given the same 5 questions in random order.

There needs to be just as many instances of participants seeing 1b then 2b as 2b followed by 1b. Does that make sense?

@TysonGersh this does make sense. In that case I would use Survey Flow for your randomization. It will pick A-H for the condition and use branching logic to show the appropriate questions.

In your survey editor you will have a block that is 6 questions long for each of your 16 conditions. E.G. Block Condition 1A will show that image, and then have the 5 questions and be set to randomize those 5 questions but always leave the image first.

You can find an example attached (I only built out two conditions). In the Survey Flow I gave you an example of how you can randomize whether 2A or 1A comes first. But if 1 should always come first then you will use the set up for 1A and 1B.

Areas to look at:
* Block randomization
* Survey Flow
I'm trying to figure out how to open this file right now. I've created a new blank survey and am trying to import it via the tools-> import option, but it doesn't actually load anything?
Wait, just kidding, Apparently I had to exit and re-enter the survey from the home page for the changes to take effect.

Working through it now. Will confirm when I've got it all worked out thank you
