Final answer:
Norte Chico likely had a monarchic form of government, evidenced by signs of hereditary leadership and social hierarchy within the society. The large-scale activity evident in Norte Chico was farming, based on archaeological findings of domesticated crops.
Step-by-step explanation:
Norte Chico, also known as the Caral civilization, was an ancient civilization located in the Andes region. Evidence suggests that this civilization likely had some type of powerful hereditary leadership and social divisions indicating a hierarchical society. Large-scale architecture and the remains of communal spaces at archaeological sites suggest activities like feasting were common, possibly indicating a form of government that organized such events. Moreover, Norte Chico's reliance on agriculture, indicated by domesticated crops such as squash, beans, avocados, and potatoes, points away from large-scale hunting as a primary activity. Therefore, from the given options, the most likely form of government in Norte Chico was monarchic, and the large-scale activity evident was farming.
