Final answer:
Aging populations and immigration patterns are examples of demographic changes that can influence American politics, affecting priorities and policy debates.
Step-by-step explanation:
Two examples of demographic change influencing American politics are aging population and immigration patterns. An aging population can lead to shifts in policy focus toward healthcare and retirement funding, as older voters have different priorities compared to younger voters. On the other hand, immigration patterns can alter the demographic composition of the electorate, potentially influencing policy debate on topics such as immigration reform, education, and the economy. Technological advancements are not directly a demographic factor but can influence society and politics in various ways. Economic inequality, while significant, is also not a demographic change per se but can be influenced by shifts in demographic factors. Thus, options a) and b) are correct in this context.
