Triumba birds reside in the polar regions and need to migrate to warmer areas in winters since winters in the polar regions are not conducive to the survival of the birds. In recent years, because of some unanticipated genetic changes, the flying capability of the birds has been declining and is expected to continue do so in the future.

Which of the following statements is best supported by the passage above?

A)At least one species that resides in the polar regions cannot survive in the summer by migrating to other regions.

B)If Triumba birds don’t develop measures to counter adversarial genetic changes, they face a likelihood of extinction.

C)Over the past few years, some of the Triumba birds would not have flown back to the polar regions because of limited flying ability.

D)Unless Triumba birds develop an ability to live in the polar regions during winter, they will be extinct in some time.

E) The flying capability of Triumba birds is worse than that of other polar region birds that do not migrate to warmer areas in the winter.

Chose B , it speaks about adversarial genetic changes.

Which of the following statements is best supported by the passage above?


A)At least one species that resides in the polar regions cannot survive in the summer by migrating to other regions.
This choice is out of the scope. The argument focuses on "Triumba birds" only, not other species.

B)If Triumba birds don’t develop measures to counter adversarial genetic changes, they face a likelihood of extinction.
Correct. This choice uses "likelihood" that is better than "will" in choice D.

C)Over the past few years, some of the Triumba birds would not have flown back to the polar regions because of limited flying ability.
This choice is out of the scope. No given information indicates that those birds would not have flown back because of limited flying ability.

D)Unless Triumba birds develop an ability to live in the polar regions during winter, they will be extinct in some time.
This choice has problem with "will". "will" indicates really high probability. The given information just suggests that those birds have some problems.

E) The flying capability of Triumba birds is worse than that of other polar region birds that do not migrate to warmer areas in the winter.
This choice is out of scope.

B)If Triumba birds don’t develop measures to counter adversarial genetic changes, they face a likelihood of extinction. -Correct

C)Over the past few years, some of the Triumba birds would not have flown back to the polar regions because of limited flying ability. -May be possible. But the argument is talking about movement FROM colder regions, not TO colder regions.

D)Unless Triumba birds develop an ability to live in the polar regions during winter, they will be extinct in some time. -Exaggerated

E) The flying capability of Triumba birds is worse than that of other polar region birds that do not migrate to warmer areas in the winter. -Out of scope

Very good question

The answer is B
The argument talks about the genetic changes in Triumba birds , reducing the birds' ability to fly .
A is irrelevant to the argument .
B is correct
C It is wrong if they have limited flying ability then they would not have reached warmer areas
D Changes the context of the argument as we are concerned about the migration of the birds .

A does not directly link with the passage. A does not indicate a specific species that relate to the Triump birds.
E is out of scope.
B is better than D b/c D is too extreme. "likelihood" in B is correct.
Stuck with B and C, now I know that C is out of scope, C talks about the summer, and even if C is true, C does not seem like an inference b/c C frankly is stated in the passage.

I believe you can do better in Gmat.
