B. occurred before the rise of the first sedentary communities.

D. involved no food plants, but instead was used to increase the production of utilitarian plants such as bottle gourds and hemp.
E. was begun but then abandoned before there was a chance for societies to develop into states.
Question 2
What have new dating techniques applied to plant remains revealed about the origins of domestication in the New World?
A. Evidence of Mexican peanut hulls dating back 15,000 years confirms that the origin of domestication in the New World preceded food production everywhere else in the world by more than 5,000 years.
B. Evidence of Peruvian squash seeds dating back 10,000 years that were found but were not domesticated in the highlands are proof of even earlier New World domestication, probably in South America's tropical lowlands.
C. Evidence of Ecuadorian potatoes dating back 5,000 years suggests that food production originated in the New World as the result of growing population pressures, particularly in the South American Andes.
D. Food production in the New World was a result of knowledge brought by the first settlers to the Americas, who crossed Beringia approximately 18,000 years ago.
E. Food production had originated independently in five different regions of the Americas by 12,000 B.P.
