Correct Option: A. Family Planning Unit of Nigeria Explanation of the Correct Answer: The question asks which option is NOT a cause of high population growth in Nigeria. To understand this, we need to analyze each option in the context of population growth.

1. Family Planning Unit of Nigeria (Option A):
2. The Family Planning Unit is designed to provide education and resources to help families plan the number and spacing of their children.
3. Effective family planning typically leads to a reduction in population growth rates because it allows families to make informed decisions about childbearing.
4. Therefore, rather than being a cause of high population growth, the Family Planning Unit aims to mitigate it. This makes Option A the correct answer, as it does not contribute to high population growth.

Explanation of the Other Options:

1. Improved Medical Facilities (Option B):
2. Improved medical facilities lead to better healthcare services, which can reduce mortality rates and increase life expectancy.
3. While this can contribute to population growth by allowing more people to live longer, it does not directly cause high birth rates. However, it can indirectly lead to higher population growth if birth rates remain high while death rates decline.
4. Thus, this option is a factor that can contribute to population growth, making it a weaker choice compared to Option A.
5. Reduction in Death Rate (Option C):
6. A reduction in the death rate is a significant factor contributing to population growth.
7. When fewer people die due to improved healthcare, nutrition, and living conditions, the population increases, especially if birth rates remain unchanged or high.
8. This option is a direct cause of high population growth, making it a strong contributor.
9. Improved Hygiene (Option D):
10. Improved hygiene practices lead to better health outcomes, reducing the incidence of diseases and infections that can cause death.
11. Similar to improved medical facilities, better hygiene can lower the death rate, contributing to population growth.
12. This option also directly contributes to high population growth, making it a valid cause.

Summary of Key Points:

• Correct Answer: A. Family Planning Unit of Nigeria is NOT a cause of high population growth; it aims to reduce it.
• Improved Medical Facilities and Improved Hygiene both contribute to lower death rates, which can lead to higher population growth.
• Reduction in Death Rate is a direct cause of population growth, as it allows more individuals to survive longer.
• Understanding the role of family planning is crucial in discussions about population control and growth.

Revision Summary:

• Family planning aims to reduce population growth, not increase it.
• Improved medical facilities and hygiene lower death rates, contributing to population growth.
• A reduction in the death rate directly leads to higher population numbers.
• Recognizing the difference between causes of growth and measures to control it is essential for understanding population dynamics.
