Hi Olivia,

For a rule replacement question like this, we need to find a new rule that has the exact same impact- that is, it does not eliminate any possibilities the original rule allowed, and it does not allow any possibilities that were previously prohibited.

(D), that J and M cannot be together, would allow for the following possability.

T: L O K
F: J M N

Since this is not allowed by the original rules, D would not have the same impact as the initial rule.

(A) would, as the initial rule sets up two blocks: L/O M N and L/O K J. A preserves these two blocks.
