I belive the answer to the first one is no I would have to assume a habitual zone is one area on a planet. for example, an air conditioned building vs. the Savvanah dessert. However I am not sure maybe other answers will help more on this one. Sorry.... Earth-like planet would of course need water, plant life, animals, oxygen, fossil fuels etc. A challenge we would face on a travel to another liveable planet: do we have engough transportation? engough fuel to make it? How long can we live on this planet? Who or what else is present here? etc. Yes I do think they should discover a planet with earth like qualities befor investing in tools to get us to them. So money is not wasted. (make sure to put this into your own words )
The document that's selected based on the information illustrated is The Rule and Grandeur of Moctezuma.
<h3>How to illustrate the information?</h3>
It should be noted that Montezuma was one of the last Aztec emperors and uder his rule, the Aztec empire were at their best conquering other tribes as well as expanding their territories.
During the reign, the Aztec Empire reached its greatest size and through warfare, Moctezuma was able to expand the territory as far as south of the Xoconosco in Chiapas and Isthmus of Tehuantepec. He also incorporated the people of Zapotec and Yopi into the empire. However, he allowed the Spanish to conquer them due to his religious superstition.
Hernán Cortés was one of the many Spanish explorers who would follow in Columbus's wake and he lived in the West Indies for over a decade before violating orders and invading what would become Mexico.
Furthermore, Moctezuma died in the evening hours in 1520, in his palace in the Aztec capital, while a prisoner of the Spanish conquistadors.

Unless extraterrestrial humans enter Earth or people leave to inhabit another planet, net global immigration and emigration are both zero. Thus, to reduce the rate of global population change, the number of births must be reduced or the number of deaths must be increased.
