Final answer:
Political barriers, characterized by conflicts emerging from power relationships, are indeed true. These barriers manifest in internal and external struggles over power, control, and wealth, thereby influencing political dynamics and outcomes such as government shutdowns and the rise of alternative political movements.
Step-by-step explanation:
Political barriers indeed refer to conflicts arising from power relationships. This is a true statement in the context of political science and sociology. Modern-day conflicts are fueled by the quest to gain or protect power and wealth, which can manifest in various ways, including the control over land, resources, liberty, and autonomy. Internally, groups such as political parties and factions contend to achieve their preferred outcomes within a governmental system. A prime example illustrating this dynamic is how political differences over budget issues can lead to substantial impacts, such as the shutdown of the federal government, reflecting the intense power struggle within political relationships. Added to this, the rise of alternative political movements, such as the Tea Party, signifies how various groups vie for influence and control within the political landscape.
