I need hlep with archaeology homework

i have reading to read and answer 4 questions in one page with 11 hours.

1) Who were the Lapita Culture and why are they important to the history of the peopling of the Pacific Islands?  Where do we think the Lapita language came from?  Where do we think their pottery style came from.

2) How far into the Pacific did the Lapita make it?

3) When did the “Second Wave” of exploration into eastern Polynesia occur?  Why would this wave of exploration and settlement have been more difficult than the voyages made by the Lapita people?

4) According to the article, what role does Anderson think El Niño events played in the dispersal of people to the far eastern Polynesian Islands?  Why might this theory be controversial to modern Polynesians?
