Explanation:
eliminate tariffs on intra-Africa trade, making it easier for businesses to trade within Africa and benefit from their own growing market; introduce regulatory measures such as sanitary standards and eliminating non-tariff barriers to trade; establish, in the future, a Common Continental Market.
Answer:
The correct answer is letter "B": personal ethics.
Explanation:
Personal ethics refers to the moral principle people consider inherent in themselves that drive their behavior. These principles extend to every aspect of their lives and are mainly noticeable in the professional field. Respect, honesty, integrity, and fairness are some examples of personal ethics.
Answer:
(a) (i) Define the term "Green Revolution" as used during the period 1945 to 1985.
- The use of modern agricultural techniques became widespread around many regions in the world. This led to higher yields through the use of fertilizers, pesticides, genetically modified seeds and mechanical machinery.
(ii) Explain the principal agricultural practices/technologies associated with the green revolution.
- extensive use of fertilizers, pesticides, genetically modified seeds and mechanical machinery.
(iii) Name TWO regions, in different parts of the world, where the green revolution has had a significant impact on crop yields.
- In North America, Mexican food production increased and they stopped importing food. Although currently that has reversed, and it is importing even more food than before.
- In Brazil, agricultural production increased dramatically. Both total farmed area and yields have continued to increase in the past years becoming a threat to the amazon basin.
(b) Identify and discuss TWO social, political, or cultural conditions necessary for the success of the agricultural practices/technologies of the green revolution.
- Emigration from rural areas to urban areas which resulted in a rapid expansion of urban centers. Since less labor was needed in farms, many people left rural areas due to lack of jobs.
- People started accepting genetically modified crops, which were not well accepted at first. A lot of money was invested in research and development of new seeds, fertilizers and pesticides.
(c) Identify and discuss TWO significant economic or ecological factors that may limit the long-term success of the agricultural practices/technologies of the green revolution.
- Many new agricultural techniques have resulted in a decrease of soil fertility. In many places crops cannot grow unless a lot of fertilizer is used.
- Countries were the green revolution was originally successful, like Mexico (where it started), have reduced the total area dedicated to crops. As the yields increased, the price of food started to decrease and many small farms could not keep operating.
If the marginal product for that employee is greater than for the previous employee hired, it must be that there are gains from specialization
<h3>
What is marginal product ?</h3>
- The marginal product or marginal physical productivity of an input (factor of production) in economics, and particularly neoclassical economics, is the change in output that results from using one more unit of a specific input (for example, the change in output when a firm's labor is increased from five to six units), assuming that the quantities of other inputs are kept constant.
- The marginal product is the mathematical derivative of the production function with respect to that input if the output and the input are infinitely divisible, in which case the marginal "units" are infinitesimal.
- When more of one input, such as labor, is used while maintaining a constant level of the other input, such as capital, the marginal product initially rises according to the "rule" of declining marginal returns.

Answer:
X=97.24
Explanation:
PV = Present Value = X+2000 by the 16th years
PMT = Payments = $100
FV = Future Value = 2000 at the end of 16 years
n= number of years
Applying the equation of future value for annuity
FV = pmt* ((1+r)ⁿ - 1
)/r
Inputting the values;
2000=100*((1+r)¹⁶-1)/r
Solving for r, gives r = 2.9%
Therefore using the formula for PV for annuity;
PV=PMT*(1-(1/1+r)/r)
X=100*(1-(1/1.029)/0.029
X=100*((1-0.9718)/0.029)
X=100*(0.0282/0.029)
X=97.24
