I am currently getting familiar with problems using Scaffolding.po (see the attached .pg file). I want to split a sample problem on matrix multiplication, into two (possibly scaffolded) parts:

1. Given matrices A and B, determine the size of the Matrix C = A * B

2. (if 1 was answered correctly): Give the actual result of the multiplication.

The problems is the following (see the attached screenshot): While previewing the answer for part 1, the matrix structure needed for part 2 is already revealed, even though the part 2 is not visible yet.

Do you have an idea of how to fix this problem, or an even better approach?

Best wishes, Fabian
