1 Language Acquisition Almost all humans acquire at least one language before the age of five Although people gain vocabulary throughout their lifetimes even young children are able to understand and produce complex sentences with complicated meanings How do children accomplish this remarkable feat in such a short amount of time Do adults learn language differently from children Linguistic researchers have long debated the answers to these questions but most agree that both nature and nurture are involved in language acquisition They disagree however about how much linguistic knowledge children have from birth and thus whether genetics or experience is more important in language acquisition How do the second and third paragraphs work together They present a scientific debate and then discuss what all linguists agree on They present a specific theory and then propose a novel study to prove it They present a general argument and then explain a specific theory They present a general arqument and then disprove a counterargument
