Question

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.
order the key details to create a summary of the text.
studying language acquisition will help us understand
language and the brain more broadly.
some experts focus on the role of environmental factors
in language acquisition.
some experts believe innate factors explain childrens
language development.
acquiring a language is complicated, and it involves both
nature and nurture.

Explanation:

The text first presents the phenomenon of language acquisition (almost all humans acquire at least one language before five, children can understand and produce complex sentences). Then it poses questions (how children achieve this, do adults learn differently). It mentions that linguistic researchers agree nature and nurture are involved but disagree on the proportion. The key details should be ordered starting from the general statement about language acquisition being complex (involving nature and nurture) which is the main conclusion. Then the two - opposing views (innate factors - nature, environmental factors - nurture) follow. The last detail about understanding language and the brain more broadly is an extension that is not directly related to the main debate in the text.

Answer:

1. Acquiring a language is complicated, and it involves both nature and nurture.
2. Some experts believe innate factors explain children's language development.
3. Some experts focus on the role of environmental factors in language acquisition.
4. Studying language acquisition will help us understand language and the brain more broadly.
