Infants younger than six months who have normal hearing can readily distinguish between acoustically similar sounds that are used as part of any language-not only those used in the language spoken by the people who raise them. Young adults can readily distinguish between such sounds only in languages that they regularly use. It is known that the physiological capacity to hear begins to deteriorate after infancy. So the observed difference in the abilities of infants and young adult to distinguish between acoustically similar speech sounds must be the result of the physiological deterioration of hearing.
The reasoning in the argument is flawed because the argument
A. sets an arbitrary cutoff point of six months for the age below which infants are able to distinguish acoustically similar speech sounds
B. does not explain the procedures used to measure the abilities of two very different populations
C. ignores the fact that certain types of speech sounds occur in almost all languages
D. assumes that what is true of a group of people taken collectively is also true of any individual with that group
E. takes a factor that might contribute to an explanation of the observed difference as a sufficient explanation for that difference

OFFICIAL EXPLANATION
(A) No. While the passage discusses infants younger than six months, there is nothing in the passage that states this ability disappears immediately at six months of age.
(B) No. This is irrelevant. The passage is about similar but different speech sounds.
(C) No. This is irrelevant.
(D) No. There is no discussion of individuals in the passage.
(E) Yes. There might be several factors that contribute to the observed difference in ability to distinguish similar sounds. For example, perhaps the tion of the brain that identifies and interprets sounds responds differently in infants than in adults.

We are given an explanation here about the deteriorating of hearing with age.
But there can be other reasons too for this. Thus we cannot conclude the age is the only factor that is responsible.
Option E says the same thing hence the correct answer.
