Few linguists would argue against the view that our first language is acquired and not learned. Pre-school children do not study their native tongue nor do they learn grammar rules but, by the time they start school at the age of five or six, the vast majority are competent users of their language. Therefore, when learning a second or additional language, studying grammar is a waste of time and all that is required is exposure to the target language in order to acquire competency in its use.
Which one of the following identifies the underlying assumption of the above argument?
A. Only people who know how to read can learn a second or additional language.
B. Languages are fundamentally different from one another.
C. Children are better at acquiring languages than adults.
D. Learners of second or additional languages should read the target language.
E. Acquiring a second or additional language is the same process as acquiring a first language.
