Turbidity. As your book/question states it is a measurement of cloudiness in water.
Answer: A belief imbued with the Aztec tradition.
Explanation:
In the "Flower Wars", the Aztecs decimated neighboring tribes, bringing their inhabitants to temples and sacrificing them to their gods. Arriving in the capital of Aztec in 1519, Cortes and his were horrified by the bloody scenes they saw. The unbearable stench of blood spread through the city. It was the tribes who used the Aztecs for their ritual ventures to become allies and spies of the Spanish.
The defeat of the last ruler of Aztec Moktezum II facilitated the traditional belief of Aztec in the return of the god Kuetzalkoatal, which prompted the Aztecs to identify the creed with the arrival of Cortes and see him as their deity. By 1521, Cortes had liquidated his native land and eliminated the possibility of any further rebellion and resistance.
Militarily they gained stronger weaponry and more mass weaponry to attack with, while economically they now had the ability to mass produce things like wool and textiles, but they both wanted and needed more to keep the industry going, and Africa had untapped potential for them.
