*Questiоns 27-29 аre bаsed оn the fоllowing: In Wisconsin аnd other places, “garlic mustard”—a plant introduced from Europe—is considered an “invasive” species. According to the United States Department of Agriculture (USDA), an invasive species is a species “that (a) is non-native (or alien) to the ecosystem under consideration, and (b) whose introduction causes or is likely to cause economic or environmental harm or harm to human health.” Garlic mustard is particularly problematic because it quickly takes over in areas where it is dispersed, crowding out or inhibiting the growth of native plant and tree species.
