We know by the law of contrapositive that this is equivalent to ~q -> ~p
which is
If the camera focus is not on manual, then switch B has not been pressed.
28. p: The student council is right; q: The administration is wrong.

Combining => p <-> q
which is
The student council is right if and only if the administration is wrong.
29. p: The prisoners will be set free; q: there are peace talks.
Given: p <-> q
This can be split as p -> q and q -> p
which are
