Answer:
The demographic transition model is characterized by relatively low growth rates at stage 1 and stage 4.
Explanation:
A is not correct because the demographic transition model has proven to be very reliable over time and that it manages to predict the population dynamics very precisely.
B is not correct because it is not just Russia's population that has been predicted well, but it is the case for most of the countries.
C is not correct because the demographic transition model has more than two stages.
D is not correct because this model doesn't predict that technology will be used to extand the limits of food production, thus it is not portrayed in a negative manner.
E is correct because stage 1 has high birthrates and high death rates, the population is still living in more primitive manner and bad conditions, and the growth is very mall, while stage 4 is the stage where the population is living in good conditions and has a high standard of living, with birthrates dropping, and the population gradually aging.
True. In Western and Central Africa, the lifetime risk of maternal death is 1 in 17.

Because most fossils are a hundred, thousand years old, even a million years old...65 million years, that is for the fossils of dinosaurs
Answer:
Awareness, education, preparedness, and prediction and warning systems can reduce the disruptive impacts of a natural disaster on communities. Mitigation measures such as adoption of zoning, land-use practices, and building codes are needed, however, to prevent or reduce actual damage from hazards.
Answer:
The correct answer is A. Country X has the higher natural increase rate.
Explanation:
Natural increase rate is the excess of fertility over mortality, that is, the difference between the number of births and deaths over a period of time; making the basis for population growth.
As Country X has a crude birth rate of 40 and a crude death rate of 15, its population's natural increase rate is 25. In turn, Country Y has a crude birth rate of 20 and a crude death rate of 9, so its population's natural increase rate is 11. So, as we can see, Country X has a higher natural increase rate.
