the highest birthrates?
A. Low economic status, more access to technology
B. High economic status, more access to technology
C. Low population density, less access to technology
D. High population density, low economic status
Answer:
A human community with high population density and low economic status will have the highest birthrates.
Explanation:
A is not correct because usually, these are populations in countries that are transitioning from one political to another political model, and these populations actually tend to decline, mostly because of immigration.
B is not correct because such populations tend to have low birthrates, often even below the bar for simple replacement of the population.
C is not correct because such populations tend to live in very bad conditions, so despite having relatively high birthrates, they stagnate in their growth.
D is correct because such populations have both the numbers needed and also live in more traditional societies, leading to very high birthrates, as can be seen with Nigeria, Ethiopia, Pakistan, Indonesia, etc.

What is the name of the country labeled with the number 1 on the map above?
Answer:
Number one is Mexico
The name of the country labelled with the number 1 on the map above is Mexico.
What is the prehistory of Mexico?The prehistory of Mexico stretches back millennia. The earliest human artefacts in Mexico are chips of stone tools found near campfire remains in the Valley of Mexico and radiocarbon-dated to circa 10,000 years ago.
Mexico is the site of the domestication of maize, tomato, and beans, which produced an agricultural surplus. This enabled the transition from paleo-Indian hunter-gatherers to sedentary agricultural villages beginning around 5000 BCE. In the subsequent formative eras, maize cultivation and cultural traits such as a mythological and religious complex, and a vigesimal numeric system, were diffused from the Mexican cultures to the rest of the Mesoamerican culture area. In this period, villages became denser in terms of population, becoming socially stratified with an artisan class, and developing into chiefdoms.
The most powerful rulers had religious and political power, organizing the construction of large ceremonial centres.
