Another must be true question. When a game has many of these, it’s a sure sign you need to have made many deductions.
A doesn’t have to be true. In scenario 1, V is on the first shelf.
Scenario 3 proves B doesn’t have to be true. We could fit V, W and F on the third shelf.
C doesn’t have to be true, the scenario from question 15 proves both grammars can be on the same shelf.
D doesn’t have to be true. The scenario from question 15 proves we can put W on the second shelf with either monograph (S or P.)
E is CORRECT. If we put W on shelf one then we can’t put P, S and V on separate shelves.
