In the field of archaeology, it has long been accepted that the ancient civilization of Xanadu was characterized by a highly centralized political system, with power concentrated in the hands of a single ruler. However, recent excavations at several sites across the Xanadu region have uncovered evidence of diverse architectural styles and distinct administrative systems, suggesting that there may have been multiple power centers in Xanadu. This raises a paradox: if Xanadu had a centralized political system, why is there evidence suggesting multiple power centers?

Which of the following, if true, would most help to resolve the apparent paradox?

(A) The architectural styles and administrative systems discovered at the different sites are all consistent with what is known about other civilizations with centralized political systems.
(B) The population of Xanadu was highly mobile and often moved from one power center to another as conditions changed.
(C) The diverse architectural styles found at the different sites were all developed during roughly the same time period.
(D) The rulers of Xanadu periodically relocated their capital to different regions in order to maintain control over their vast territory.
(E) The excavated sites are located in areas that were known for their abundant natural resources and strategic importance.

The paradox:

Old belief: Xanadu = one centralized political system (one ruler).
New evidence: multiple sites show different architectural styles and administrative systems, which looks like multiple power centers.

How (D) resolves it:
If the single ruler periodically moved the capital, then:

Each former capital region would naturally develop its own administrative structures and architectural features.
These “multiple power centers” are not independent centers of power — they are sequential capitals of one centralized authority.

Thus, the appearance of multiple centers is fully consistent with a centralized political system.

Paradox resolved.



Why the other choices don’t work

(A) Saying the styles and systems are “consistent with centralized civilizations” does NOT explain why multiple distinct centers exist.
It just says it's possible, not why it happened.

(B) Population mobility does not explain administrative differences or architectural distinctions that look like separate centers of power.

(C) Everything being from the same time period does nothing to reconcile “centralized vs. multiple centers.”
Still looks like decentralized power.

(E)Natural resources and strategic importance explain why sites were occupied, not why they have distinct architectures or administrative systems.

Correct Answer: (D)

(D) The rulers of Xanadu periodically relocated their capital to different regions in order to maintain control over their vast territory.
(E) The excavated sites are located in areas that were known for their abundant natural resources and strategic importance.

The Paradox:
1. Premise 1 (Accepted View): Xanadu had a highly centralized political system (power in the hands of a single ruler).
2. Premise 2 (New Evidence): Excavations show diverse architectural styles and distinct administrative systems at different sites, suggesting multiple power centers.
3. The Conflict: How can a civilization be centralized (one ruler) but leave physical evidence that looks like it had multiple independent power centers (diverse systems)?

We need an option that explains the physical evidence (diverse sites) without contradicting the historical fact (centralized system).

Analysis of the Options:

(A) Incorrect. Stating that the findings are "consistent with other civilizations" might suggest this is normal, but it doesn't explain the logic of why it happened in Xanadu. It appeals to external comparison rather than solving the internal puzzle.

(B) Incorrect. The mobility of the population doesn't explain why the administrative systems and architecture were distinct. If the people moved constantly, we might expect more homogeneity (sameness), not distinct systems.

(C) Incorrect. This option actually makes the paradox harder to resolve. If the diverse styles were developed at the same time, it strongly implies different rulers or independent states operating simultaneously. This conflicts with the idea of a single centralized ruler.

(D) Correct. This resolves the paradox perfectly. If the single ruler periodically moved the capital to different regions to maintain control, there would physically be multiple "capital cities" found by archaeologists. However, at any given point in time, there was only one center of power. This explains the "diverse architectural styles" (built in different regions or times) and "distinct systems" (adapted to local needs) while preserving the "centralized" political structure.

(E) Incorrect. This explains where the sites were located (near resources), but it does not explain why they had distinct administrative systems or architectural styles that suggest multiple power centers.

Answer: D
