The male Druicing Songbird is known for its elaborate mating call in the springtime. Researchers have concluded that the Druicing Songbird's mating call is actually a culturally acquired, rather than a genetically transmitted trait. Researchers base this conclusion on the fact that different local populations of Druicing Songbirds sing mating songs with different melodies and cadences.

Which of the following, if true, would most strengthen the conclusion drawn by the researchers?


A) There are more common characteristics than there are differences among the mating song styles of local Druicing Songbirds.

B) Young male Druicing Songbirds are inept at mating calls and apparently spend years listening to their elders before perfecting the local mating song.

C) The songs of one sub-species of Druicing Songbirds are notably less melodious than all the other sub-species.

D) Druicing Songbirds are only found on an archipelago of islands in the South Pacific, and are therefore isolated by portions of the ocean from each other.

E) Druicing Songbirds are considered to be some of the most intelligent of all songbirds.

IMO it’s B, since B indicates that Druicing Songbirds perfect the mating calls by training, so that the differences should not come from the genetic differences

Answer B
Perfecting the local mating song is culturally acquired by young male Druicing Songbirds from years of listening to their elders.

A) There are more common characteristics than there are differences among the mating song styles of local Druicing Songbirds. - thus doesn't indicate whether the song is learned or genetically adapted.

B) Young male Druicing Songbirds are inept at mating calls and apparently //spend years listening to their elders before perfecting the local mating song.// - they spend years listening until they perfect at it. Thus, it means they learn it over time. Hence, it cannot be genetically adapted. It is instead learned in the local area. Looks good. Keep.

C) The songs of one sub-species of Druicing Songbirds are notably less melodious than all the other sub-species. - Irrelevant.

D) Druicing Songbirds are only found on an archipelago of islands in the South Pacific, and are therefore isolated by portions of the ocean from each other..... Ok. So what ??

E) Druicing Songbirds are considered to be some of the most intelligent of all songbirds. - intelligence is not the concern. Irrelevant.

Thus, B is best.

To strengthen the conclusion we need a factor which will signify the importance of after birth parameters which affect the elaborate mating calls of these birds.
So, let's find a factor in the same direction.


Quote:
A) There are more common characteristics than there are differences among the mating song styles of local Druicing Songbirds.
This option doesn't tell us anything about a parameter which affects the mating calls. Negate this option, you won't weaken the conclusion. Out of Scope.

Quote:
B) Young male Druicing Songbirds are inept at mating calls and apparently spend years listening to their elders before perfecting the local mating song.
This is an option which tells us something about their habits and relations with their elders which affect their calls. If we negate this option, then our conclusion is weakened. Good option. Let's keep it.

Quote:
C) The songs of one sub-species of Druicing Songbirds are notably less melodious than all the other sub-species.
This is totally irrelevant to our conclusion. If we negate it, we don't get anything. So it's irrelevant.

Quote:
D) Druicing Songbirds are only found on an archipelago of islands in the South Pacific, and are therefore isolated by portions of the ocean from each other.
This is not telling anything about any parameters which will affect these birds' habits. So it's irrelevant.

Quote:
E) Druicing Songbirds are considered to be some of the most intelligent of all songbirds.
Totally irrelevant.

So the best answer is B.
