PrepTest 64, Section 3, Question 1
"Hot spot" is a term that ecologists use to describe those habitats with the greatest concentrations of species found only in one place�so-called "endemic" species. Many of these hot spots are vulnerable to habitat loss due to commercial development. Furthermore, loss of endemic species accounts for most modern-day extinctions. Thus, given that only a limited number of environmental battles can be waged, it would be reasonable for organizations dedicated to preserving species to _______.

Which one of the following most logically completes the argument?
try to help only those species who are threatened with extinction because of habitat loss
concentrate their resources on protecting hot spot habitats
treat all endemic species as equally valuable and equally in need of preservation
accept that most endemic species will become extinct
expand the definition of "hot spot" to include vulnerable habitats that are not currently home to many endangered species
