4. 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.

B it is
Density of crabs is a concern of the birdwatcher and B appropriately addresses this.
A. Every year a certain percentage of crabs are caught by fishermen as bait for eel traps.
Out of scope
B. Horseshoe crabs are so prolific that given favorable circumstances their numbers increase rapidly.
Correct choice
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.
Would actually weaken the mayor's proposal
D. The additional land made available by the reclamation project will give migrating shorebirds more space.
The argument does not state whether the shoebirds need more space. Hence out of scope.
E. Some of the migrating shorebirds make only one stop during their migration form South America to Canada.
Totally out of scope

B, which means the "density" of crab will go up, counters birdwatcher's claim.
