Some species of Arctic birds are
threatened by recent sharp increases in the population of snow geese, which
breed in the Arctic and are displacing birds
of less vigorous species.  Although snow
geese are a popular quarry for hunters in the southern regions where they
winter, the hunting season ends if and when hunting has reduced the population
by five percent, according to official estimates.  Clearly, dropping this restriction would
allow the other species to recover.

    

 

    

Which of the following, if true, most
seriously undermines the argument?

A.   
Hunting limits for snow geese were imposed
many years ago in response to a sharp decline in the population of snow geese.

    

B.   
It has been many years since the restriction
led to the hunting season for snow geese being closed earlier than the
scheduled date.

    

C.   
The number of snow geese taken by hunters
each year has grown every year for several years.

    

D.    As their
population has increased, snow geese have recolonized wintering grounds that
they had not used for several seasons.

    

E.     In the
snow goose’s winter habitats, the goose faces no significant natural predation.
