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.

Conclusion which needs to be strengthen:
Druicing Songbird's mating call is actually a culturally acquired, rather than a genetically transmitted trait.
A) There are more common characteristics than there are differences among the mating song styles of local Druicing Songbirds.
It can be because of any reason which includes genetically acquired trait also. So, No.
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 clearly tells us that the acquired characteristic is because of culture than genetics. Exactly what we were looking for.
C) The songs of one sub-species of Druicing Songbirds are notably less melodious than all the other sub-species.
How does it help us in the conclusion.
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.
Still we are not getting any information regarding the transfer of the trait.
E) Druicing Songbirds are considered to be some of the most intelligent of all songbirds.
Irrelevant.

This strengthen question was quite easy, perhaps because there is an OG question with a similar ideology ( about birds and their nests) and also cause Gmatninja has solved that one exquisitely
Conclusion: the Druicing Songbird's mating call is actually a culturally acquired, rather than a genetically transmitted trait.
Pre-think: find answers that suggest they inherit other traits or skills culturally.
B is completely in line with pre-thinking hence is the correct answer!!
B is the correct answer !
