Children develop the ability to form the sounds necessary for speech between the ages of two and five. A team of linguists studied groups of children between two and five years of age in several regions of Australia and found that children pronounced certain phonemes differently in different regions. For example, children from a rural town in the South consistently pronounced the phonemes differently from their counterparts in Sydney. The linguists concluded that pronunciation of these phonemes is learned from contact with adults and other children and not inherited genetically.
Which of the following, if true, would lend the most support to the linguists' conclusion?
A. There are more similarities than differences found in the pronunciation patterns of any two groups of Australian children involved in the study.
B. Compared to the younger children in the study, the older children who had begun preschool were consistently better able to pronounce the phonemes.
C. Children from one of the regions studied had more difficulty pronouncing certain phonemes than did the children from every other region.
D. Australian children under the age of six have little contact with adults or children outside their region.
E. It has been proven that young children acquire social behavior patterns from contact with others and not through genetics.

Only answer choice (B) gives us more reason to believe that pronunciation is learned rather than inherited. If older children who have had more contact with others in a school setting demonstrate better pronunciation, then we have more reason to believe that pronunciation is learned.
Answer choices (A) and (C) are irrelevant comparisons. Neither answer gives more credence to learning or genetics as an explanation of how pronunciation is acquired. Choice (D) is out of scope since without more information we don't know what effect contact with people outside the region might have on pronunciation. Answer choice (E) is also out of scope because it refers to social behavior, which has no clear link to pronunciation.

B has a fault : The ARGUMENT is about "DIFFERENTLY" pronouncing phonemes and NOT ABOUT "BEING better able to pronounce the phonemes"
to prove that this PROCESS IS not GENETIC but is learned the AUTHOR should have studied THOSE AUSTRALIAN babies who have settled in some other region .
B DOES not prove that THIS PROCESS is NOT GENETIC . B just claims that older kids are BETTER ABLE to PRONOUNCE the phonemes ---->this could very well be a genetic development, a tendency that develops with age . case in point : diabetes is GENETIC disorder but it is MORE PRONOUNCED with AGED people or in there words it gets MORE DEVELOPED in OLDER PEOPLE than in TEENAGE PEOPLE ---->by this we cannot conclude that OLDER PEOPLE GETS this DISEASE from OTHER PEOPLE around them !!

Hi aditya8062,
Few more points to add.
Option B talks about older people (We don't care about them)
The argument is concerned with younger children and that too between 2 to 6.
I don't see any valid answer in this.
I really wish that gmatclub should also have some prerequisites before posting any question.
Because of limited resources, its very difficult to practice within scope of GMAT standard questions
