The answer is D. The Palaeozoic era was characterized by the supercontinent of Pannotia which was located at the current position where Chile is, 500 million years ago. There is evidence that shows that central Africa was once at the polar regions due to evidence of glaciers in its geological rocks. Due to tectonic movement, the Appalachians and the Ural Mountains were formed in the resulting Pangea supercontinent.
Answer:
B. Geocentric solar system
Explanation:
The scientific community is the one that accepts or dismisses theories. Some theories are accepted, and that is because there are enough evidence that support them, while some theories are dismissed as they have been proven over time that they are not correct.
One of the theories that is outdated and has been dismissed by the scientific community is the theory of the geocentric solar system. This theory has been in place and widely accepted for a very long time, pretty much two millenniums.
This theory was basically suggesting that the Earth is the center of the solar system. The Sun, Moon, all the other planets that were known, as well as the stars, were all orbiting around the Earth. This has been proven as wrong (except that the Moon is orbiting around Earth), and that the theory is far away from the truth, so naturally once there were enough evidence it was dismissed.

Answer:
The planning of governments when it comes to running their countries is always based on demographics, and this is because the characteristics of the population are crucial for the planning and which direction it will go.
Explanation:
Every government makes plans about running the country based on the demographic characteristics of its population. The reason for this is that the characteristics of the population are crucial for developing and focusing on certain sectors or avoiding others. Each country in the world has its own unique population with unique characteristics and this brings in a lot of different policies by the different governments.
If a population is highly educated, the government can focus its planning on the territary and quaternary economic sectors, as it will primarily have a labor force that would be most efficient in these sectors. If a population is very young, uneducated, and with a low level of skills, the chances are that the government will focus the country toward agriculture and extraction of natural resources, thus the primary sector. If a population is old and it is projected to get older then the government would most probably adopt a policy to invite people from other countries to move in that will contribute to its socio-economic development.
