The Mammillaria cactus M. anniana occurs naturally only in the state of Tamaulipas in Mexico, and the smallness of its range makes it especially vulnerable to extinction. The traditional single-species approach to conservation emphasizes the need to focus on individual species most at risk, like M. anniana, but recently, conservationists have argued that an ecosystem-based approach that incorporates the many interactions between the climate, terrain, and various species of a given geographical area may lead to better outcomes for all the species in a given location. If this view is correct, the single-species approach to the conservation of M. anniana could thus __________

Which choice most logically completes the text?

fail to consider the ways in which the survival of M. anniana may be influenced by changes in the populations of other species that inhabit Tamaulipas.

erroneously shift the focus of conservation efforts away from M. anniana itself.

lead to a better understanding of how the distribution of Mammillaria species throughout Mexico has affected their survival.

allow conservationists to better consider how climatic changes affecting Tamaulipas may reduce the number of species competing with M. anniana.
