  1. The country with the largest population in Africa is Algeria. Egypt. India. Nigeria. South Africa.

  2. The country with the largest population in Africa is Algeria. Egypt. India. Nigeria. South Africa. Explanation: Nigeria is Africa’s population leader. India is not located in Africa. South Africa is an economic leader.

  3. The number of people per unit of arable landis the arithmetic density. physiological density. agricultural density. land-use density. population density.

  4. The number of people per unit of arable land is the arithmetic density. physiological density. agricultural density. land-use density. population density. Explanation: This is the definition of physiological density which is different from arithmetic and agricultural densities.

  5. The spread of the Avian flu through Egypt and Sudan is most closely associated with which geographic feature? A major interstate highway The Nile River The ridgeline of a mountain range The Trans-African railway The Orinoco River

  6. The spread of the Avian flu through Egypt and Sudan is most closely associated with which geographic feature? A major interstate highway The Nile River The ridgeline of a mountain range The Trans-African railway The Orinoco River Explanation: The Nile is the major north-south transport route in Egypt and Sudan.

  7. Which of the following is the least significant factor affecting population growth rates? Doubling times Sex ratio Total fertility rate Crude death rate Crude birth rate

  8. Which of the following is the least significant factor affecting population growth rates? Doubling times Sex ratio Total fertility rate Crude death rate Crude birth rate Explanation: Sex ratio refers to the percentage of men and women born in a country. The other terms are closely related to the rise and decline of population size.

  9. Which of the following countries has the highest infant mortality rates? Venezuela Greenland Iceland Mali Saudi Arabia

  10. Which of the following countries has the highest infant mortality rates? Venezuela Greenland Iceland Mali Saudi Arabia Explanation: Like its neighbors in Saharan Africa, Mali has some of the highest infant mortality rates in the world.

  11. In which stage of the demographic transition are birth rates stable and death rates declining? Stage 1 Stage 2 Stage 3 Stage 4 This situation does not occur in any of the four stages.

  12. In which stage of the demographic transition are birth rates stable and death rates declining? Stage 1 Stage 2 Stage 3 Stage 4 This situation does not occur in any of the four stages. Figure 2-14 clearly shows stable birth rates and declining death rates in stage 2.

  13. Population growth rates are lowest in _________ of the demographic transition. stage 1 stage 2 stage 3 stage 4 stage 5

  14. Population growth rates are lowest in _________ of the demographic transition. stage 1 stage 2 stage 3 stage 4 stage 5 Explanation: High birth and death rates negate one another in stage 1 and result in very low population growth.

  15. Dependency ratios are highest in Africa. South America. Europe. North America. East Asia.

  16. Dependency ratios are highest in Africa. South America. Europe. North America. East Asia. Explanation: With the highest birth rates, Africa—and other places in stage 2 of the Demographic Transition—has a large proportion of dependents among its population.

  17. Which stage of the Epidemiologic Transition is characterized by a decreasing number of deaths from infectious diseases and a rising toll from degenerative diseases? Stage 1 Stage 2 Stage 3 Stage 4 Stage 5

  18. Which stage of the Epidemiologic Transition is characterized by a decreasing number of deaths from infectious diseases and a rising toll from degenerative diseases? Stage 1 Stage 2 Stage 3 Stage 4 Stage 5 Explanation: Infectious diseases characterize stages 1 and 2. Stage 5 marks the resurgence of infectious and parasitic diseases.

  19. The most lethal global epidemic disease in recent years has been tuberculosis. malaria. AIDS. SARS. Ebola.

  20. The most lethal global epidemic disease in recent years has been tuberculosis. malaria. AIDS. SARS. Ebola. Explanation: While tuberculosis and malaria are deadly killers, none of the choices exceeds the global destruction caused by AIDS.

  21. Which of these continents has the highest agricultural density? Asia Australia Europe South America North America

  22. Which of these continents has the highest agricultural density? Asia Australia Europe South America North America Explanation: China, India, and other Asian countries still have a large percentage of the workforce that are farmers.

  23. Which of these continents has the highest crude death rate? Asia Australia Europe South America North America

  24. Which of these continents has the highest crude death rate? Asia Australia Europe South America North America Explanation: Europe’s overall population is older than any other continent.
