Contrary to popular belief,the Mayans were not united as one empire is
<em>(A) TRUE.</em>
The <em>Maya</em> lived in three separate sub areas with distinct environmental and cultural differences.The Maya civilisation was never united,rather it consisted of many small states ruled by kings,each apparently centered on a city.At times, a stronger Maya state would dominate a weaker Maya state and be able to exact tribute and labour from it.
The Maya is a Mesoamerican civilisation noted for Maya script,the only known fully developed writing system of the pre Columbian America,as well as,for its art,architecture and mathematical and astronomical systems.
The Maya had <em>no central king ruling</em> their big empire.Instead,there were 20 different states,similar to ancient Greece city states.

A consequence would be a loss of diversity among the world. By making everyone westernized we lose a lot of culturally unique parts of the world. I hope this helped.
