Hi, we have our initial setup in which we know that L and M teach the same language, and since that language cannot be f or r, it must be g.

J _ L/M_
S _ L/M_
F g r

For this question we know that p is at the junior school and doesn't teach French, so P must teach R. This also enables us to place N at the senior school.

J _ L/M P
S _ L/M N
F g r

This is why D must be true.
