I am working through the logic games bible (just started) and hit a bit of a snag. Here is the game

A doctor must schedule nine patients L,M,O,P,R,S,T,V, and X - during a given week, monday through Sunday. At least one patient must be scheduled for each day, and the schedule must observe the following constraints:

M and S must bed scheduled for the same day

On the day P is scheduled, P must be the only patient scheduled to see the doctor.

Exactly one patient is scheduled for wednesday

T cannot be scheduled for thursday

if P is scheduled for MOnday, then V and X must be scheduled for Saturday

R is not scheduled for thursday unless L is scheduled for Monday

question

If L is scheduled for monday, which one of the following must be true?

the correct answer is - P is not scheduled for monday

I understand this, as it is fairly simple, but I dont understand why another option they threw in is wrong.

That option is - R is scheduled for thursday.

I took the final rule to be similar to a "you will not get an A unless you study" IT seems that as L is scheduled for monday, the sufficient condition is satisfied, and R must be schedule for thursday
