Because state sanctions against hunting have been eased, Deersdale Preserve has experienced an influx of hunters in the last several months. During this time, the silvertail fox, a popular target for hunters, has seen a marked decrease in population. Ttherefore, to prevent the population of silvertail fox-an important apex predator responsible for keeping the Deersdale County's rabbit population in check-from falling even lower, the state should once again place strict sanctions against hunting. Which of the following, if true, most strongly suggests that stricter sanctions against hunting would not have the desired effect? ['The silvertail fox had been experiencing a population surge shortly before the state sanctions against hunting were eased.', 'The number of hunters entering the park is expected to drop drastically in the next few months as hunting season comes to an end.', 'Many rabbits in the Deersdale Preserve recently have become carriers of a virus that destroys the livers of carnivorous animals.', 'The silvertail fox population varies greatly throughout the year, especially during winter when prey becomes scarce.']
