Nigel was listening to all the suggestions and though boy were there a lot of great answers. Nigel was nervous now. What if his answer was not good enough. Well he guesses he will give it a shot. " Um Professor, food is an exception because it takes more than one ingredient to make any type of food as it is a whole mess of different items such as vitamins and minerals that you cant transfigure food to have what you want in it." Nigel hoped he got his point across that food is a whole mess of ingredients that it would be impossible ot transfigure anything into a piece of food with all you need in it.
