What is the key difference between arithmetic and physiological population density?
Correct Answer
A. Arithmetic is total population divided by total land and physiological is total population divided by total arable land.
Explanation
The key difference between arithmetic and physiological population density is the type of land that is considered in the calculation. Arithmetic population density takes into account the total land area, including both arable and non-arable land, while physiological population density only considers the total arable land area. This means that physiological population density provides a more specific measure of population density in relation to the land that is suitable for agriculture and food production.
2.
Which of the following would properly express the population pressure in Egypt?
Correct Answer
D. Physiological population density.
Explanation
The physiological population density is a measure of the number of people per unit of arable land. This measure takes into account the carrying capacity of the land and the resources available to support the population. In the case of Egypt, which has a high population density and limited arable land, the physiological population density would properly express the population pressure.
3.
What three areas contain the vast majority of the world's population?
Correct Answer
B. Europe, East Asia, South Asia.
Explanation
The three areas that contain the vast majority of the world's population are Europe, East Asia, and South Asia. These regions have high population densities and are home to several highly populated countries such as China and India. Europe has a long history of urbanization and industrialization, leading to a concentrated population. East Asia, particularly China, has the largest population in the world. South Asia, including countries like India and Pakistan, also has a significant population due to its large land area and high birth rates.
4.
My country is going through a population explosion. What demographic stage[s] is it likely in?
Correct Answer
E. Stage 2 and Stage 3
Explanation
If your country is experiencing a population explosion, it is likely in either Stage 2 or Stage 3 of the demographic transition model.
In Stage 2, birth rates remain high while death rates decrease due to improvements in healthcare, sanitation, and nutrition. This leads to rapid population growth.
In Stage 3, birth rates start to decline as society undergoes industrialization and urbanization. However, death rates continue to decrease, resulting in continued population growth, albeit at a slower rate than in Stage 2.
5.
I pass a billboard on the road in which a small, Causcasian family is smiling and laughing, put up by the government. What logical conclusions can I draw from observing this billboard?
Correct Answer
A. The country is practicing restrictive population policies.
Explanation
C isn't correct because even though the people on the billboard ARE Caucasian, nothing in the billboard suggests that they are being favored OVER other races. (They had to use some race, didn't they?)
6.
What is the root cause[s] of high CBR and CDR in the first stage of demographic transition?
Correct Answer
E. All of the above are correct
Explanation
The root causes of high CBR (Crude Birth Rate) and CDR (Crude Death Rate) in the first stage of demographic transition are lack of food leading to famine, lack of sanitation, and epidemics and instability. These factors contribute to a high birth rate due to the need for larger families to ensure survival, as well as a high death rate due to malnutrition, disease, and unsanitary living conditions. Therefore, all of the above options are correct as they all contribute to the high CBR and CDR in the first stage of demographic transition.
7.
My nation is mainly comprised of young teenagers and young adults- why, I'm one of the VERY few old people. What would my population pyramid look like, you think?
Correct Answer
C. Pyramid
Explanation
The correct answer is "Pyramid" because a population pyramid is a graphical representation of the age and sex distribution of a population. In this case, since the nation is mainly comprised of young teenagers and young adults, the pyramid would have a wide base representing a large proportion of the population in the younger age groups, and it would gradually taper off towards the top, indicating a smaller number of older individuals. This shape is characteristic of a pyramid-shaped population distribution.
8.
Who sounded the 'warning bells' about population in the early 1700s?
Correct Answer
Malthus
Thomas Malthus
Explanation
Thomas Malthus sounded the 'warning bells' about population in the early 1700s. He was an economist and demographer who published his influential work "An Essay on the Principle of Population" in 1798. Malthus argued that population growth would eventually outstrip the availability of resources, leading to widespread poverty, famine, and social unrest. His ideas sparked debates and discussions about the relationship between population and resources, and his work continues to be influential in the field of population studies.
9.
A high birthrate means population growth. True, or false?
Correct Answer
False
Explanation
A high birthrate does not necessarily mean population growth. Population growth depends on various factors such as birthrate, death rate, and migration. While a high birthrate can contribute to population growth, it can be offset by a high death rate or significant outmigration. Therefore, it is not accurate to say that a high birthrate always leads to population growth.
10.
A megalopolis is a large ____ center.
Correct Answer
urban
Explanation
A megalopolis is a large urban center. This means that it is a densely populated area that consists of multiple cities and their surrounding suburbs. Megalopolises are characterized by their high population density, extensive infrastructure, and diverse economic activities. They are often major hubs for commerce, culture, and innovation, attracting people from various backgrounds and offering a wide range of opportunities and amenities.
11.
Stationary population level requires a TFR among women of ____.
Correct Answer
2.1
Explanation
The stationary population level requires a Total Fertility Rate (TFR) among women of 2.1. This means that on average, each woman needs to have 2.1 children in order to replace herself and her partner in the population. A TFR of 2.1 is considered the replacement level fertility, where the population neither grows nor declines over time. If the TFR is below 2.1, the population will gradually decrease, and if it is above 2.1, the population will increase.
12.
My dad's heart failed the week before. He died as a result of a ____ disease.
Correct Answer
chronic
degenerative
Explanation
The given sentence states that the person's dad's heart failed, and he died as a result of a disease. The words "chronic" and "degenerative" both describe long-term conditions that progressively worsen over time. Therefore, it can be inferred that the correct answer is a combination of both "chronic" and "degenerative" to indicate that the disease was a long-term condition that led to the failure of the heart.
