Final answer:
The correct answer fills the blanks with political, religious, and cultural life, representing the spheres where upper classes historically held top positions.
Step-by-step explanation:
The upper classes historically have enjoyed significant advantages in various areas of society. Upper classes were able to avoid physical labor and occupied top positions in political, religious, and cultural life. This separation is evident in various aspects of lifestyle, including their attire, their homes, and even the rituals surrounding their burial practices. These social distinctions were often exacerbated by the economic changes brought by the Industrial Revolution, creating new class divisions and cultural identities.
