Linkage

[ChicaRosa]

I got confused with the example on the example that states:

1.W and X cannot speak consecutively

2. X must speak third or fifth


then after this there was a diagram linking the two rules where X was given a split dual option for the 3rd and 5th space and W being crossed out underneath the 4th space.

I understand why W cannot be in the 4th place but wouldn't that mean that W cannot be in the 2nd and 6th space as well since it would break the rule about W and X not being able to speak consecutively?

Thank you!

Hello ChicaRosa,

But you don't know that for sure. What if, say, X were in 5th place? There would be nothing preventing W from being in 2nd place. (Though it sure couldn't be in 6th place!) So, the only definite thing you know is that W can't be in 4th place.

Hope this helps,
David

Hi Chica,

The key here is to see that W can't be in 2 in some cases, and in other instances W can't be in 6. So, you are partially correct, but instead of it being a constant thing, those cases are dependent on where X is. Because X moves around, the limitations on W move around. The restriction on W being in 4 is constant however, because it's the one point that overlaps in all the scenarios for where X is placed.

I hope that helps. Thanks!
