Some species of Arctic birds arethreatened by recent sharp increases in the population of snow geese, whichbreed in the Arctic
and are displacing birds of less vigorous species. Although snow geese are a popular quarry for hunters in the southernregions where they winter, the hunting season ends if and when hunting hasreduced the population by five percent, according to official estimates. Clearly, dropping this restriction would allow the other species torecover.
Which of the following, if true, mostseriously undermines the argument?
A.Hunting limits for snow geese were imposed many years ago in response toa sharp decline in the population of snow geese.
B. It has been many years since the restriction led to the hunting seasonfor snow geese being closed earlier than the scheduled date.
C. The number of snow geese taken by hunters each year has grown every yearfor several years.
D. As their population has increased, snow geese have recolonized winteringgrounds that they had not used for several seasons.
E. In the snow goose’s winter habitats,the goose faces no significant natural predation.
