They definitely wrote this question so it's confusing to see what's going on! However, I think if we set it up as an ordering game with multiple subjects in each position then it becomes clear that we can work it out as a sequencing game. Try working it out like this: _ _ _ _ _ A B C D E where we use the grade as the position instead of a number. I would say it's not really a multi-linear question because for those we have multiple variable sets that we are assigning. For example, the paradigmatic ML question is ordering five musicians and also deciding whether they play cello or violin. Here, we are just ordering (albeit in a difficult to see way). Hope this helps!
