Complete Question:
The project represented by this resource load chart (see attached) has a maximum limit of 6 units of resource activity in any day. The first activities that are strong candidates for shifting are:
A) Activity A
B) Activities B and C
C) Activities D and E
D) Activity E and F
Answer:
The first activities that are strong candidates for shifting are:
C) Activities D and E
Explanation:
Activities D and E have a total time of 5 days altogether based on the attached resource load chart. They have the least time and can be shifted to accommodate other activities before they can be tackled sequentially.
A resource load chart displays the total amount of resources required as a function of time in any given project. It is the best method for establishing the existence of some resource conflicts across project activities, especially when compared to Gantt Charts, Network Diagrams, and Pareto Diagrams.
Answer:
Prices ensure an equal distribution of goods and services among consumers.
Explanation:
The price mechanism helps in the efficient allocation of resources. There are a number of functions performed by the price mechanism. Prices send signals regarding resources. An increase and decrease in prices reflect surplus and deficit.
Price balances the demand and supply of a product. Price is inversely related to demand and positively related to the supply of a product. It is determined by the interaction of demand and supply and helps in balancing supply and demand.
For instance, an increase in demand would increase the price, this higher price will motivate the suppliers to increase quantity supplied thus balancing demand and supply.
Price helps in coordinating economic activities and helps buyers and sellers in decision making. However, they do not help in equal distribution of goods and services among consumers.
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:
The right option is option b, which is Ethical dilemmas
Explanation:
Ethical dilemmas are situations in which there is a choice to be made between two options neither of which resolved the situation. It is a decision making problem which is between two possible moral imperatives.
