Explanation:

Lacking resistance to Old World pathogens conveyed by the Spanish, Hispaniola's indigenous occupants succumbed to horrible sicknesses of smallpox, flu, and different infections.  

In April 1520, Spanish powers arrived in what is presently Veracruz, Mexico, accidentally carrying along an African slave tainted with smallpox. After two months, Spanish troops entered the capital of the Aztec Empire, Tenochtitlán, and by mid-October the infection was clearing through the city, killing about half of the populace, which researchers today gauge at 50,000 to 300,000 individuals.

The dead incorporated the Aztec ruler, Cuitláhuac, and a large number of his senior consultants. When Hernán Cortés and his troops started their last ambush on Tenochtitlán, bodies lay dispersed over the city, enabling the little Spanish power to overpower the stunned safeguards.

the correct answer is “opportunity cost”. opportunity cost is what a company misses out because it decided in one option over another one. in this case, the company decided to invest in building a factory so it gave up another possible benefit or profit in order to achieve success with the factory.  

trade-off is not the correct answer since it is a situation in which you accept losing something in return for benefits in other areas.

and finally, consequence is a general term used to accept what it comes when you make a decision. it can be a positive or negative consequence depending if the decision you took was the correct one.
