Professional Cook Level 1 Practice Test

The key idea here is how vegetables are classified in plant families. Broccoli, cauliflower, cabbage, and kale are all cultivars of the same species, Brassica oleracea, which places them in the cabbage family, Brassicaceae. Because they come from the same species and share many characteristics—like cruciferous flavors, crisp textures, and similar cooking methods—they’re considered closely related. So there isn’t actually a vegetable in this list that isn’t a member of the cabbage family; the statement in the question doesn’t fit the botanical reality.
