After the first bite, the Mystery Recipe Contest judge has detected cumin, red pepper flakes, and lemon grass in the winning dish. These seasonings have a tendency to be potent, producing distinct flavors. Since the quantity of any seasoning in a recipe depends directly on how potent that seasoning tastes in the dish, the judge has determined that the dish contains cumin, lemon grass, and red pepper flakes, in order of decreasing relative quantity. The judge's argument relies on which of the following assumptions? ['The winning dish contains at least one other seasoning ingredient besides cumin, lemon grass, and red pepper flakes.', 'The judge was unable to detect any other seasonings in the winning dish.', 'The bite that the judge took was representative of the whole dish.', 'Recipes that contain cumin generally contain other spices that are more potent.']
