Marks: +1, -0

The Burmese ferret badger burrows its home in the ground. Based on the fact that different local populations of Burmese ferret badgers of the same species dig homes of different styles, zoologists have concluded that the badgers building
styles are a culturally acquired, rather than a genetically transmitted, trait.
Which of the following, if true, would most strengthen the conclusion drawn by the zoologists?

There are more common characteristics than there are differences among the Burmese ferret badger’s styles of the local Burmese ferret badger population that has been studied most extensively.
Young Burmese ferret badgers are inept at digging burrows and apparently spend years watching their elders before becoming accomplished in the local style.
The homes of one species of badger lack the characteristics of the homes of most other species of badger.
Burmese ferret badgers are found only in Burma and India, where local populations of the badgers apparently seldom have contact with one another.
It is well known that the squeals of some badgers are learned rather than transmitted genetically.
