If anything gets in the way of our good eating, it’s lifestyle. When you get home from work late, why spend an hour in front of the stove when you can spend two minutes at the microwave? And doesn’t that oatmeal box claim to be a good source of calcium for our kids, never mind the small print listing 14 grams of sugar? A small soda at the movies could satisfy a family of four. Even schools have vending machines. What would make the author's argument more effective?
offering a reason to support her opinion

providing a quotation from a credible source

recognizing and refuting a counterclaim

motivating readers with a call to action
