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.
ANS:B
看過很多帖子的解答~~~大概能了解~B就是強調restriction沒有發揮功效~!
不過~~不懂restriction
是指什麼意思?? 若是指5%的禁令~所以代表不用有restriction ~
就可以很快達到5%嗎?? 還是指hunting season的 期間長短?
感謝指點~~!!
