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:
0.875
Explanation:
The income elasticity of demand measures the responsiveness of quantity demanded to changes in income.
Income elasticity of demand = percentage change in quantity demanded / percentage change in income
14% / 16% = 0.875
Demand is inelastic because the coefficient of elasticity is less than one.

Answer:
$800
$1,000
The quantity of money demanded decreases as the interest rate rises.
Explanation:
a
To calculate the opportunity cost on government bond at 8%, we use the following method
Opportunity Cost for 8% interest rate on Government Bonds
= (8/100)%× $10,000
= 0.08% ×$10,000
= $800
To calculate the opportunity cost government at bond on 10%, we use the following method
Opportunity Cost for 10% interest rate on Government Bonds
= (10/100)%× $10,000
= 0.1%×$10,000
= $1,000
b. The quantity of money demanded decreases as the interest rate rises.
The inflation rate was 5.9 percent between the first and second years, and 8.3 percent between the second and third years. Hence, A is the correct option.
When we compare the values for any two periods or locations it reveals the average change in prices between the two periods or the average difference in prices between locations, the price index is a measure of relative price changes.
Take the Market Basket's price for the interest-bearing year, divide it by the Market Basket's price for the base year, then multiply the result by 100 to get the Price Index.
Price indices typically pick a base year and set that year's index value to 100. As a proportion of that base year, every other year is expressed. Let 2000 serve as the basis year in this illustration: In 2000, the index's initial value was $2.50; since $2.50/$2.50 = 100%, the index's current value is 100.
