Why did the Inca engage in continuous expansion?(1 point)
1 The need for laborers after the failure of the mit’a made it necessary to conquer new lands.
2 The Inca lacked resources for their pastoral lifestyle, so they conquered grazing lands owned by other groups.
3 Land could not be inherited by new rulers, so they had to expand the empire to gain more wealth and power.
4 The Inca's conflicts with the Wari and Tikawanu civilizations forced them to grow the empire for more power.
