新GRE小短文阅读练习题五十四
Eve r y fall, thousands of Canada geese migrate from Canada to the eastern UnitedStates.Recently, however, these geese have faced intense competition for food
from a subspecies of Canada goose that lives year-round in the eastern United
States.To prevent the nonmigratory population from endangering the migratory
geese, some groups have proposed allowing hunting of the nonmigratory geese.
But since most hunters cannot visually distinguish the two subspecies, allowing any
hunting is surely unwise.
Which of the following, if true, most seriously weakens the argument?
A Hunting of the migratory Canada geese is permitted in some parts of Canada.
B During the summer, only the nonmigratory geese are present in the eastern
United States.
C The migratory Canada geese do not interbreed with the nonmigratory Canada
geese.
D The migratory subspecies and the nonmigratory subspecies are not the only
two subspecies of Canada geese.
E The groups that have proposed allowing hunting of the nonmigratory geese
have thoroughly studied both goose populations.
