LG Game 3 Question 18 Explanation, by LSATHacks
P can’t go on Wednesday. So there are only two possibilities here for the divisions toured on Tuesday and Wednesday: SS or OO.
We can also figure out that P has to go on Monday.
Why? Well, O can never go on Monday.
S also can’t go on Monday, because then S would also be inspected on Tuesday. But the local rule says that whoever is inspected on Tuesday has to be inspected on Wednesday, too. S can’t be inspected on three days (rule 4).
So P has to go on Monday. This is testing the same deduction as in questions 16 and 17! If S doesn’t go on Monday, P goes there.
Here are the two possibilities. In the first diagram, Thursday-Friday could be OP or PO.
A is CORRECT.
B doesn’t have to be true in the first diagram.
C doesn’t have to be true in the second diagram.
D doesn’t have to be true in the first diagram.
E doesn’t have to be true in the second diagram.
