The most likely reason for the difference in world rank for fixed lines and cellular phones in the African countries of Nigeria, Ghana, and Mali is option D. Cell phones are more necessary in countries with a shortage of reliable fixed lines.
There are several factors that support this explanation. Firstly, fixed lines require extensive infrastructure and investments to establish and maintain. In many developing countries, including those in Africa, the infrastructure for fixed lines may be inadequate, especially in rural areas. This leads to a shortage of reliable fixed-line connections, making it difficult for people to access telecommunications services through traditional landlines.
On the other hand, cellular phones provide a more flexible and accessible communication option. The rapid growth of mobile technology has allowed countries to bypass the need for extensive fixed-line infrastructure and directly adopt cellular networks.
Mobile phones can be easily distributed and operated even in areas where fixed-line connections are scarce or unreliable. They offer greater convenience and accessibility, enabling individuals to communicate and access information regardless of their location. The prevalence of cellular phones in African countries is also influenced by factors such as affordability and demographics. Therefore, the correct answer is option D.

December 21 June 21 Discuss how an equinox occurs in 5-8 lines. Explain with respect to equator, length of day and night, both hemispheres and dates. (1x6)
An equinox occurs when the Earth's axis is not tilted towards or away from the Sun, resulting in equal length of day and night at all latitude along the equator.
An equinox occurs twice a year, around March 21 and September 21, when the tilt of the Earth's axis is inclined neither away from nor towards the Sun. In the case of the March equinox, the Sun crosses the celestial equator, and in the September equinox, it crosses back southward.
With respect to the equator, during the equinoxes, the Sun is directly overhead at noon on the equator, resulting in equal length of day and night. This means that both day and night are approximately 12 hours long at all latitudes along the equator.
In both hemispheres, the equinox marks the transition between seasons. For the Northern Hemisphere, the March equinox signals the start of spring, while the September equinox marks the beginning of autumn. Conversely, in the Southern Hemisphere, the March equinox denotes the beginning of autumn, while the September equinox heralds the start of spring.
The dates of the equinoxes, around March 21 and September 21, are determined by the Earth's position in its orbit around the Sun. These dates may vary slightly from year to year due to the complexities of the Earth's orbit.

A government which holds total power over a country, affecting both the economy & society, is know as a_______state.
A government that holds total power over a country, affecting both the economy and society, is known as an authoritarian state.
In an authoritarian state, power is concentrated in the hands of a single individual or a small group of individuals who exercise control over all aspects of governance and decision-making. This type of government often suppresses political dissent, restricts civil liberties, and maintains strict control over the economy.
In an authoritarian state, the government's influence extends beyond political matters and into the economic and social realms. The state exerts control over industries, trade, and resources, often implementing central planning and state ownership of key sectors. Individual freedoms and rights may be curtailed, with limited political participation and freedom of expression. Censorship and surveillance are commonly used to maintain control and suppress opposition.
Authoritarian states can have varying degrees of control, ranging from mild to extreme, but they all share the common characteristic of centralized power and limited individual freedoms. These states often prioritize stability and control over individual liberties and democratic processes, leading to significant challenges in achieving political pluralism, economic diversification, and social progress.
