The correct response is: Australia promoted the use of scientific racism when determining who would receive rights, while France used a policy of intermarriage.
This reflects the fundamental differences in the approaches of the two countries towards assimilationist policies regarding Indigenous peoples. Australia’s policies were characterized by a focus on race and the promotion of "scientific" criteria for determining rights and privileges, while France pursued a more integrationist policy that encouraged intermarriage and the incorporation of Indigenous peoples into French culture.
