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.
Answer: $59,780.65
Explanation:
To find out what she would accept today, we need to apply the present value formula which is= V.P(1+i)^-n
So, $80,000(1+6%)^-5= $59,780.65
Income elasticity of demand measures the receptiveness of the quantity demanded for a good or service to a change in income.
It's calculated as the ratio of the percentage change in quantity demanded to the percentage change in income.

Hope this helps!!
Answer:
The answer is 5.47 percent
Explanation:
Firstly, we find coupon payment (PMT).
it can be gotten from the price (present value) of bond formula:
PV = PMT/(1+r)^1 + PMT/(1+r)^2 ....... PMT + FV/(1+r)^n
N = 10.5 years
1/Y = 6.2 percent
PV = $945
PMT = ?
FV = $1000
Using a Financial calculator to input all the variables above,
Annual PMT = $54.72
Semi annual will be $54.72/2= $27.36
Coupon rate is Annual PMT /par value
= $54.72/1000
0.0547 or 5.47 percent
