Everyone hates rule substitution questions. But they’re not that hard if you consider that the only way to replace a rule is to use the other rules.
Looking at the full effect of all the rules helps you decide how to replace the rule. For instance, look at the setup diagrams for this game:
W is pretty restricted. They can only go first or second. Who can go in front of W?
- Not K and L. Rule 3 says they go after.
- Not T. It goes after K.
- Not Y, because Z needs to go before Y.
(Don’t worry, I explain the third bullet below)
So only Z can go before W. A is CORRECT.
The final bullet point is the hardest to understand, so I made a diagram to show what happens if we put Y before W:
Putting Z and Y before W pushes W third, and this pushes L fourth, which isn’t recorded. So that violates the rule from the setup that L must be recorded. You get the same result with K.
(K and L can’t go sixth. See the setup for the full explanation. But basically, you either have KT in 5th and 6th, or L in 5th, and K somewhere earlier, because it goes before T)
