HIV/AIDS as an epidemic has the potential to: A. increase the human population B. stabilise the human population C. wipe out the human population D. accelerate human reproductive capabilities

Here are the solutions to questions 4, 5, and 6.

Question 4:
HIV/AIDS as an epidemic has the potential to:
A. increase the human population
B. stabilise the human population
C. wipe out the human population
D. accelerate human reproductive capabilities

• Explanation: HIV/AIDS is a deadly disease that increases mortality rates, especially among the reproductive-age population. This leads to a reduction in population growth or even population decline. Options A and D are incorrect as they suggest an increase or acceleration. Option B, "stabilise," is generally incorrect as an epidemic destabilizes population dynamics. While "wipe out the human population" (C) is an extreme and hyperbolic statement for the entire global population, it is the only option that points to a severe negative demographic impact consistent with a widespread, deadly epidemic, implying a significant reduction in population.

The correct option is C.
C) $\boxed{\text{wipe out the human population}}$

Question 5:
HIV/AIDS is mainly spread through
A. blood transfusion
B. having unprotected sex
C. sorcery and cannibalism
D. sharing eating utensils with infected persons

• Explanation: The primary mode of HIV/AIDS transmission globally is through the exchange of bodily fluids, most commonly during unprotected sexual intercourse. While blood transfusions can transmit HIV, they are not the main route of spread in most regions due to screening. Options C and D are incorrect.

The correct option is B.
B) $\boxed{\text{having unprotected sex}}$

Question 6:
Between which groups does socio-economic disparity exist?
A. Groups of people only
B. Widows and sex workers
C. Orphans and beggars only
D. People and groups of people

• Explanation: Socio-economic disparity refers to the unequal distribution of wealth, income, opportunities, and resources. This inequality exists both between different categories or groups of people (e.g., based on race, gender, class) and among individuals within a society. Therefore, the most comprehensive answer is that it exists between people and groups of people.

The correct option is D.
D) $\boxed{\text{People and groups of people}}$
