### HideShow timer Statistics

After observing thirty-year-old albatrosses, biologists determined that migration distance in mature albatrosses is directly tied to the lifespan of other fledglings in their brood. Albatrosses that hatched alone or whose fellow fledglings did not survive after their first molting were observed to follow shorter migration paths after thirty years than those that had been accompanied by one or more other fledglings.

If the biologists' determination is accurate, it follows that

A a few albatrosses who molted before maturity are capable of migrating further after thirty years as a result

B the migration distance of thirty-year-old albatrosses is connected to the migration distance of other fledglings

C it is the survival of other fledglings rather than just the birth of those fledglings that more directly affects the migration distance of albatrosses after thirty years

D albatrosses that migrated long distances after their first molting are more likely to migrate long distances after thirty years as well

E the lifespan of other fledglings is more important to albatrosses after their first molting than it is after thirty years

Was between C and E.

I chose C

E goes too far in saying that the lifespan of other fledglings is more important to albatrosses after their first molting than it is after thirty years.

We cannot infer that the lifespan was important or not. It was just directly related to the migration distance of albatrosses after thirty years.

Maybe the bird doesn't want to migrate and wants to relax

I hope its clear

Thank you

I select option C. I followed option elimination only to arrive at my choice. A can't be inferred from the argument as nothing was mentioned about molding before or after maturity. Choice B seemed close however it is confusing as it relates migrations distance of albatrosses to the migration distance of fledlings but the finding was about fellow fledlings. Option D & E are irrelevant. So it is C for me.
