Suppose you are learning how to bake a cake. Start by preheating the oven to 350°F and greasing a cake pan. Then, mix together flour, sugar, baking powder, and salt in a large bowl. In a separate bowl, whisk together eggs, milk, and vanilla extract. Combine the wet and dry ingredients, pour into the cake pan, and bake for 30-35 minutes until a toothpick inserted comes out clean.
Can we infer that "It is necessary to preheat the oven before baking a cake."?
