How to randomize questions?

Hi all,

My questionnaire looks like the following:

I want the order of Qc, Qd, and Qe fixed, which means respondent should see Qc first, then Qd, then Qe. Then I need to randomize the order of Qa, Qb, and (Qc, Qd, and Qe).

For example, respondents should see the following order:
Qa, Qc, Qd, Qe, Qb
Qc, Qd, Qe, Qb, Qa
Qb, Qa, Qc, Qd, Qe

I guess I need to use constructed lists. Any one could help me with that? Many many thanks!

Lighthouse Studio supports this using randomized blocks.  Within the Randomize Blocks window, set one block from Qa to Qa, one block from Qb to Qd, and one block from Qe to Qe.  Respondents will see all three blocks of questions in a randomized order.
