Top Law Schools

For this must be true Q I've diagrammed a senario which seems to conform to all the rules, yet none of the answer choices indicate this. I've got

L/PTH(F/S)/I(F/S)... in this senario it appears that family law and securities can clearly be on separate floors.

Alternatively we can have H(F/S)/PTI(F/S)/L. Still family law and securities are not forced to be on the same floor.

What am I doing wrong?

Thanks

Realized my mistake. I was slotting 3 additional slots of the middle floor instead of two.

It has to be 1/3/3 or 3/3/1 not 1/4/2 or 2/4/1.

Derp.
