Suppose The following is a recipe for making chocolate chip cookies: Preheat oven to 350°F. Mix 1 cup of softened butter with 1 cup of sugar until creamy. Add 2 eggs and 1 teaspoon of vanilla extract, then mix in 2 1/4 cups of flour and 1 teaspoon of baking soda. Stir in 1 cup of chocolate chips. Drop spoonfuls of dough onto a baking sheet and bake for 10-12 minutes. Let cool before serving.
Can we infer that "the recipe calls for 1/2 cup of butter"? Yes, no, or maybe?
