Question Options:
A. receptive language.
B. universal grammar.
C. the one-word stage.
D. two-word stage.
Answer: This is an example of UNIVERSAL GRAMMAR.
Explanation: Universal grammar can be defined as a hypothetical innate abstract system in the human brain that underlies the grammar of all human languages. This holds that some certain set of structural rules are natural to humans.
The theory of universal grammar proposes that if human beings are brought up under normal conditions, then they will always develop language with certain properties for example, distinguishing nouns from verbs, or distinguishing function words from content words.
