The pneumonic form of the plague is spread by droplets - therefore "through the air" is a correct answer. Also catching malaria does afford some degree of immunity, which is why it is generally so much more serious in children (8% of child deaths globally caused by malaria). I think that it is unfair to mark these two answers "wrong".

Thanks I'll make the plague one clearer, but it is a common misconception that you automatically become fully immune to malaria if you've had it once which is not the case.
