Letter to the editor: Your article was unjustified in criticizing environmentalists for claiming that more wolves on Vancouver Island are killed by hunters than are born each year. You stated that this claim was disproven by recent studies that indicate that the total number of wolves on Vancouver Island has remained roughly constant for 20 years. But you failed to account for the fact that, fearing the extinction of this wolf population, environmentalists have been introducing new wolves into the Vancouver Island wolf population for 20 years. Which one of the following most accurately expresses the conclusion of the argument in the letter to the editor? ['Environmentalists have been successfully maintaining the wolf population on Vancouver Island for 20 years.', 'As many wolves on Vancouver Island are killed by hunters as are born each year.', 'The recent studies indicating that the total number of wolves on Vancouver Island has remained roughly constant for 20 years were flawed.', "The stability in the size of the Vancouver Island wolf population does not warrant the article's criticism of the environmentalists' claim."]
