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.
The correct answer is B.
The interviewer will be taking notes with recommendations for the next person in the process, since the interviewer won't be the sole person making the rejection/acceptance decision.
I looked up the question, since this one is incomplete. I've attached an image of the correct chart. Elvis' marginal benefit of the fourth sandwich is his total benefit of eating 4 sandwich minus his total benefit from eating 3 sandwiches.
Looking at the chart, we see that this gives us 81-75 = 6.
Therefore, the Marginal Benefit of a fourth sandwich is 6.
Answer:
True
Explanation:
Consumer price index measures the changes in price level of a basket of goods.
If consumer price index falls if means price level has fallen , goods become cheaper and the same amount of money can buy more quantities of goods and services.
Conversely if consumer price index rises, price level has increased, goods and services become more expensive and more amount of money would be needed to maintain the same level of consumption.
CPI is calculated as cost of basket of goods in a given year / cost of basket of goods in a base year
