Accepted Answer

# Brief Explanations:
Davis and his colleagues think the rigid attitudes and militaristic metaphors in the debate about exotic species make for poor science and policy - making. This implies that non - native species management programs should be more strategic in resource use. There is no evidence in Passage 1 for the other options. For example, there is no mention of non - native species dying out quickly, stiff penalties, or ecosystems not changing without non - native species introduction.
# Answer:
Nonnative species management programs should consider more effective ways to use resources to protect the environment.
