Shortly after their daughter claire was born, aurelia and scott moved from nebraska to new zealand to work with the native population. after a few years there, claire began to speak english as well as maori, the language of the native new zealanders. this is an example of grammar.

The correct answer is universal grammar. 

Universal grammar refers to a theory coined by the linguist, Noam Chomsky. According to the theory of universal grammar, language acquisition is an inborn ability in humans with an underlying genetic basis. According to Chomsky, from infancy itself, humans are able to distinguish and identify grammatical patterns (such as frequency, intonation,etc.) that are found in different languages.
