It's the purpose and type of writing in this passage:
"While many people believe the tomato is a vegetable, it is, in fact, a fruit. The tomato fruit is consumed in diverse ways, including raw, as an ingredient in many dishes and sauces, and in drinks. While it is botanically a fruit, it is considered a vegetable for culinary purposes (as well as by the United States Supreme Court, see Nix v. Hedden), which has caused some confusion. The fruit is rich in lycopene, which may have beneficial health effects."
What is "to inform: expository"?
