Re: [問題] 兩題CR機經請教
※ 引述《vincactusi (吸)》之銘言：
: 2.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 hunter, 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?
: 答案是B.
: It has been many years since the restriction led to the hunting season for
: snow geese being closed earlier than the scheduled date.
: 我不懂為什麼?
這一題我也覺得很奇怪，B看起來像是支持結論的答案
還請高人指點..
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.
