If P is alone on 1 of 3 shifts, there are a few things that govern where he must be alone.
(1) the Morning must have more shifts than the Night
(2) If P is alone, then HT are together
(3) P cannot be assigned to a shift later than S

So, P cannot be alone on the first shift, because that would warrant the following: 1-3-1 and the morning would have an EVEN number of shifts as the night.

Additionally, P cannot be alone on the last shift either, because P's shift cannot be later than S.

Therefore, we know P is isolated on the afternoon shift. Which warrants that the HT block are on the morning, along with W, and S is scheduled for the night (again because P at the same time or before S as stated by the rules).
