How can prehistoric sites have geographic ‘place’?

The correct answer to this open question is the following.

Prehistoric sites have geographic ‘place’ because archeologist, anthropologists, historians, and other scholars have studied the places and text that refers to ancient civilizations, and that is why we can know and identify the location of determined civilization.

For instance, the Sumerians clay tablets that were written in the cuneiform language, clearly establish the story of the Sumerians, their city-states, their gods, and part of their life. That is how archeologists and historians have proved that they existed, they settled in the middle of the Tigris and Euphrates River in modern-day Iraq, in the Middle East. Due to this information, historians know that they formed great city-states such as Kish, Nippur, Eridu, or Lagash, and the archeological ruins and texts show that they built impressive buildings called Ziguratts.

The same happens with other civilizations such as ancient Greek, China, Rome, and Mesoamerican civilizations.

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.
