1.
Which of these is a disadvantage of overpopulation?
Correct Answer
A. High cost of living
Explanation
Overpopulation leads to a high demand for resources such as food, water, and housing. As the population increases, the availability of these resources decreases, causing prices to rise. This results in a high cost of living for individuals and families, as they have to spend more money on basic necessities. Additionally, overpopulation puts pressure on infrastructure and public services, leading to higher taxes and expenses for the government, which further contributes to the high cost of living.
2.
What is the process of counting the number of people living in a particular geographical location?
Correct Answer
A. Population census
Explanation
The process of counting the number of people living in a particular geographical location is known as a population census. This involves collecting data on the total number of individuals residing in a specific area, which helps in determining various demographic factors such as age distribution, gender ratio, and population growth rate. The census is usually conducted by government authorities and is carried out periodically to provide accurate and up-to-date information about the population of a given region.
3.
Which of these factors can not affect population?
Correct Answer
D. Continent
Explanation
The factor that cannot affect population is the continent. While emigration, immigration, and natural disasters can all have an impact on population size, the continent itself does not directly influence population. Population is determined by the number of individuals living in a specific area, regardless of the continent it is located in.
4.
What does low labour participation bring to population's economy?
Correct Answer
A. Population ageing
Explanation
Low labor participation can have a negative impact on the economy of a population. As the population ages, there is a decrease in the number of people who are actively participating in the workforce. This can lead to a decline in productivity and economic growth. With fewer people working, there may also be a strain on social security systems and an increase in healthcare costs. Additionally, low labor participation can result in a decrease in consumer spending, which can further impact the overall economy.
5.
Which of these works with population growth and economy development?
Correct Answer
B. Presence of raw materials
Explanation
The presence of raw materials is essential for both population growth and economic development. Raw materials are the basic resources needed for industrial production and manufacturing. They are used to create goods and services, which in turn contribute to economic growth. Additionally, the availability of raw materials can attract investment and stimulate job creation, leading to an increase in population. Therefore, the presence of raw materials plays a crucial role in supporting population growth and driving economic development.
6.
Which of these does not affect the population growth?
Correct Answer
C. Afforestation
Explanation
Afforestation does not affect population growth because it refers to the process of planting trees in an area where there were no trees before. While afforestation is important for environmental conservation and can have various benefits such as reducing soil erosion and providing habitats for wildlife, it does not directly impact population growth. Population growth is influenced by factors such as birth rates, death rates, migration, and socioeconomic factors like labor participation rate and availability of raw materials.
7.
What factor makes Antarctica a very lowly populated continent?
Correct Answer
C. Weather condition
Explanation
Antarctica is a very lowly populated continent due to its extreme weather conditions. The continent experiences extremely cold temperatures, strong winds, and heavy snowfall, making it inhospitable for human habitation. The harsh climate makes it difficult for people to survive and carry out daily activities, leading to a very small population.
8.
What is the head counting of people living in a particular geographical location?
Correct Answer
C. Population census
Explanation
A population census is a comprehensive head counting of people living in a particular geographical location. It involves gathering data on various demographic factors such as age, gender, education, and occupation. This information is essential for governments and policymakers to plan and allocate resources effectively. Population census provides an accurate snapshot of the population size and characteristics, helping in understanding population trends, estimating population growth, and making informed decisions for the development and welfare of the community.
9.
Which of these is not affected by population?
Correct Answer
D. Forestry
Explanation
Forestry is not affected by population because it refers to the management and conservation of forests and their resources, such as timber and wildlife. Population size does not directly impact the growth and maintenance of forests. However, the other options - economy, cost of living, and standard of living - are all influenced by population. A larger population can lead to increased economic activity, higher cost of living due to increased demand, and changes in the overall standard of living in a region.
10.
What is the most populated country of the world?
Correct Answer
A. China
Explanation
China is the most populated country in the world. With a population of over 1.4 billion people, it has the largest population globally. This is due to various factors such as its large land area, historical population growth, and government policies. China's population size has significant implications for its economy, social structure, and resource management.
