Why can Q not live on the 5th floor? Please explain

Q must be on three because after assigning PKO to 2, 3, and 4, we only have two completely open spots left in one and five. Since one of those must be L alone and the other must be M and N, q and j must go with either k or o. Since q can't go with o, q must go with k
