Miranda held her breath. Carefully she sniffed for the blegh smell. Hmmm it doesnt really smell like stinky feet anymore! Miranda grinned, she had done it!
But there was still a weird smell lingering, must be the parmesan.
"Odorus Subsisto Parmesan" she said firmly. Oops Miranda had accidentaly jabbed the cheese, poking a hole in it with her wand. Blegh hopefully her wand wouldnt smell bad now. Miranda was lactose intolerant, the cheeses were making her nauseaous.

She heard the professors question and looked up. "Professor, is it so that one doesn't have to get nauseated by the smell of things?" she said raising her hand. "Or maybe so that animals wont get attracted to smells of food that youre keeping somewhere, or maybe so that the smell of the food wont pass onto another food?"
