Q24

I understand why B is right; but can't A, C, E also be right?

Thanks!

A, C, and E can certainly be true, but they do not have to be true like B must be.

x: _ K P _ ...J
y: _ L _ _ ...MN

This is the information we can plug into our diagram. If you did not know that MN must be on Y and J must be on X, please tell me, as it is the must have inference in the game.

So, looking at this setup can yield the inference that R is going to be in slot 1, but whether it is X1 or Y1 is up for debate.

For extra practice, you could pretend that this was a could be true question, or a question wanting a different answer. You could frame this with R going into X1 and then R going into Y1.

X1 frame:

x: R K P _ ...J
y: _ L _ _ ...MN

You know J must now be in X4...

x: R K P J
y: _ L _ O ...MN

You know that O must now be in Y4 since O must be in a four.

x: R K P J
y: _ L _ O ...MN

You know that N must be in Y3 since we have a not rule with M. Which means that M must be in Y1.

x: R K P J
y: M L N O

Y1 frame:

x: _ K P _ ...J
y: R L _ _ ...MN

You know that with the M not rule in Y3, that N must got there and M goes into Y4, which then forces O into X4. Which then forces J into the one and only slot left in X, X1.

x: J K P O
y: R L N M

Thanks! For some reason I thought doing the second frame was enough... but now I totally get it!
