GWD17-Q34:
During the month of May, crabs arrive on Delaware’s beaches to lay eggs.  Certain shorebirds depend on these eggs for food during their annual spring migration to their northern breeding grounds.  Delaware’s crab population has declined recently.  This decline, however, poses no serious threat to the migrating shorebird populations:  by remaining longer in Delaware, the birds will be able to eat enough crab eggs to allow them to complete their migration.

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

A.    No other food available to the birds on Delaware’s beaches is as nutritious and accessible as are crab eggs.
B.    The decline in the number of crabs on Delaware’s beaches is due to the harvesting of crabs by humans.
C.    There are more crabs on Delaware’s beaches than in any other area that the migrating birds pass through.
D.    The crabs do not conceal their eggs.
E.    The earlier in the season the shorebirds complete their migration, the more likely they are to breed successfully.

When there is less rainfall than normal, the water level
of Australian rivers falls and the rivers flow more
slowly. Because algae whose habitat is river water
grow best in slow-moving water, the amount of algae
per unit of water generally increases when there has
been little rain. By contrast, however, following a
period of extreme drought, algae levels are low even
in very slow-moving river water.
Which of the following, if true, does most to explain
the contrast described above?
(A)    During periods of extreme drought, the
populations of some of the species that feed on
algae tend to fall.
(B)    The more slowly water moves, the more
conducive its temperature is to the growth
of algae.
(C)    When algae populations reach very high levels,
conditions within the river can become toxic for
some of the other species that normally live
there.
(D)    Australian rivers dry up completely for short
intervals in periods of extreme drought.
(E)    Except during periods of extreme drought, algae
levels tend to be higher in rivers in which the
flow has been controlled by damming than in
rivers that flow freely.

JJ18，鸟吃crab egg是GWD第十套，27题
Mayor:  Migrating shorebirds stop at our beach just to feed on horseshoe-crab eggs, a phenomenon that attracts tourists.  To bring more tourists, the town council plans to undertake a beach reclamation project to double the area available to crabs for nesting.

Birdwatcher:  Without a high density of crabs on a beach, migrating shorebirds will go hungry because shorebirds only eat eggs that a crab happens to uncover when it is digging its own nest.

Which of the following, if true, would provide the mayor with the strongest counter to the birdwatcher’s objection?

A.    Every year a certain percentage of crabs are caught by fishermen as bait for eel traps.
B.    Horseshoe crabs are so prolific that given favorable circumstances their numbers increase rapidly.
C.    On average, tourists who come to the town in order to watch birds spend more money there than tourists who come for other purposes.
D.    The additional land made available by the reclamation project will give migrating shorebirds more space.
E.    Some of the migrating shorebirds make only one stop during their migration form South America to Canada.
