11. GWD17-Q11:

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.

In each of the past five years, Barraland’s prison population has increased.Yet, according to official government statistics, for none of those years has there been either an increase in the number of criminal cases brought to trial, or an increase in the rate at which convictions have been obtained.Clearly, therefore, the percentage of people convicted of crimes who are being given prison sentences is on the increase.

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



A.In Barraland the range of punishments that can be imposed instead of a prison sentence is wide.

B.Over the last ten years, overcrowding in the prisons of Barraland has essentially been eliminated as a result of an ambitious program of prison construction.

C.Ten years ago, Barraland reformed its criminal justice system, imposing longer minimum sentences for those crimes for which a prison sentence had long been mandatory.

D.Barraland has been supervising convicts on parole more closely in recent years, with the result that parole violations have become significantly less frequent.

E.The number of people in Barraland who feel that crime is on the increase is significantly greater now than it was five years ago.
