A. Using information in the graph shown, compare the data trend from 1960 to 2015 for sub-Saharan Africa to the trend shown for Europe.
B. Using the data for ONE of the regions shown in the graph, explain why the trend may have an effect on the number of farms in developing countries.
C. Explain the degree to which the changes in grain yields may affect rural populations in countries in stage 4 of the demographic transition
D. Explain ONE limitation of the data in describing food insecurity at a regional scale.
Answers
Answer:
A. From the information given in the graph, we have;
The grain yield in pounds per acre for Europe in 1960 is approximately 1,600 Pounds per Acre
The grain yield in pounds per acre for Europe in 2015 is approximately 5,100 Pounds per Acre
The rate of change of grain yield in Europe ≈ (5,100 - 1,600)/(2015 - 1960) = 63.[tex]\overline{63}[/tex] Pounds per Acre per year
The grain yield in pounds per acre for Sub-Saharan Africa in 1960 is approximately 800 Pounds per Acre
The grain yield in pounds per for Sub-Saharan Africa 2015 is approximately 1,250 Pounds per Acre
The rate of change in grain yield in Sub-Saharan Africa ≈ (1,250 - 800)/(2015 - 1960) = 8.[tex]\overline{18}[/tex] Pounds per Acre per year
Therefore, the grain yield per acre per year in Europe is increasing approximately 8 times the increase in Sub-Saharan Africa
B. Given that the rate of increase in the pounds of grain per Acre per year in Europe is progressively increasing above the average rate of world rate, the market for the grains produced in Europe will be partly the developing countries, thereby reducing the number of farms found in developing countries
C. In stage 4 demographic transition the population growth is stabilizing and therefore where there is an increase in grain yields, there will be an increase in farming and economic activity and a reduction in population growth
Where there is a decrease in grain yield, there will be an increase in activities to restore supply and therefore, a reduction in population
D. One limitation of the data in describing food security at a regional scale is the information required on the population figures in a given region involved in grain farming
Explanation:
Answer: According to the graph, the grain yield in Europe is approx. 1600 (PPA) compared to the 2015 grain yield of 5100 (PPA), which would create an annual grain yield change of 63.6 pounds yearly. For Sub-Saharan Africa, the 1960's grain yield is 800 (PPA) compared to the modern 2015 grain yield of 1250 (PPA) which would create an annual grain yield change of 8.1 pounds yearly. Due to the data stating that the PPA rate of Europe is steadily increasing above the global rate, the agricultural (produce) market for European grain would be saturated with an unnecessary amount of produce, resulting in the reduction of the number of farms found in developing countries. In the demographical transition to stage 4, population growth is stabilizing and an increase in both farming and economic activity paired with a reduction in population growth will also see an increase in grain yields. One limitation of the data in terms of describing regional food insecurity at a regional scale is the lack of population data (growth and decline) to provide more accurate information/data on a region involved in agricultural farming.

Why was industrialization concentrated in the northern United States until the mid-twentieth century? The South lacked infrastructure. Northern governments subsidized industry. Pay rates were lower in the North. Unions prevented industry from moving south. The South was politically isolated.
Answers
Answer: The South lacked infrastructure.
Explanation:
The Northern part of the United States was much more industrialized than the South and this contributed in no small part to the Union victory during the Civil War.
The major reason for this was the extensive infrastructure that had been built in Northern states such as Railroad network and the ship building industries of New England. With such infrastructure providing access to markets, more industries were set up in the North to take advantage of this accessibility.

Read this excerpt from "Four Types of Volcanoes"
Volcanoes are structures formed around openings (vents) in the ground where molten lava, ash, or gas escape from inside the Earth. We have all heard of lava, but not everyone knows how it forms. Deep inside the Earth, rock that melted long ago beneath the Earth's crust forms magma, a very hot liquid that mixes with dissolved gases and crystals. When this magma flows up above Earth’s surface, it is called lava. Volcanoes can erupt continuously or only once in a while. They can erupt violently or slowly. As lava spews out of an opening, it lands, cools, and builds up hills or mountains around the vent. Therefore, volcanoes are usually found on top of hills or mountains.
What is the connection between magma and the hills or mountains around a volcano vent?
Magma that is underground pushes up against land from beneath it, so hills or mountains form over the magma.
Lava is part of magma, and it destroys the mountains and hills that are around a volcano vent.
Magma comes out of a volcano vent, becomes lava, and then cools and becomes part of the land around the vent.
Lava rises up above ground, cools into magma, and then fills the volcano vent so that a hill or mountain forms.

Why does economy doesn't work with a strong middle class?
Answers
There are essentially tiers to the social pyramid, throughout history and even today. The social pyramid typically is comprised of tiers, or classes, in which certain people would fall under. Historically (as it is easier to understand), the social pyramid would comprise of the King or government on the top, followed by the nobility, clergy and lesser nobility, soldiers and traders, commoners, and then slaves. Understanding the economic prospects was easy. The top tiers typically were born into their power, and reaped the most benefits from the labors of the merchant and commoner classes.
However, this mostly changed after the Black Death and the rise of the Renaissance, in which the old serfdom was almost instantaneously replaced due to the sharp decline of available manpower, resulting in the rise of the merchant class, in which people took up jobs that dealt with trade, either being a merchant, a producer of goods, or some form of laborer. This, in effect, was what comprised of the middle class, and the steady growth of people that fell into this category strengthened it.
The second reason that the economy doesn't work without a strong middle class, lies (in name only) on the type of economical structure the country uses. The middle class can be eliminated in name only, but structurally it still plays an important role in allowing for the cash flow to continue, which sustains the economy as a whole. What exactly, you may wonder, does this class comprise of? The middle class comprises of all the key aspects in allowing an economy to flourish, from the creation of products through production jobs, to small time business owners transacting products which, in turn, is a small part in propping up the economy.
The only time the economy fails to work with a strong middle class, is when an unexpected event occurs, whether as a natural, financial, or foreign relations development. A strong middle class is sustained through the protective layer of laws from the government that keeps the rich from exploiting the working class, as well as a stable economy, a stable foreign and domestic relations within the government, a stable governmental system in itself, etc. Even with a failure of one or a few, if corrected soon, the economy can still sustain. On a long term run however, with major upsets, a strong middle class is not enough to sustain the economy.
I'll admit, the wording of this question is weird, and can technically be interpreted both ways, hence the different explanations. A strong middle class is the basis in helping the economy thrive by providing goods, services, jobs, and other securities. On the other hand, a strong middle class is not enough in being a security against failures that result outside of the economical sphere that can, in turn, impact the economic sphere. This is typically the reason to the failure of an economical plan, even with a strong middle class.
which product was lead removed from in the United States cell phones plastics gasoline computers electrical cords
Answers
Lead was removed removed from cell phones, plastics, gasoline, computers, and electrical cords in the United States.
What is Lead?Lead is a heavy metal that is toxic to humans and other organisms. It has been used for thousands of years for a variety of purposes, including in plumbing, paint, and gasoline.
However, exposure to lead can have serious health effects, particularly on the developing brain and nervous system.
In the United States, lead was removed from gasoline and some types of plastics. Lead was used as an octane booster in gasoline until it was phased out in the 1970s due to environmental and public health concerns.
Lead was also used as a stabilizer in some types of plastics, but this practice had largely been phased out by the 1990s due to concerns about lead exposure.
In the United States, lead was not commonly used in the manufacture of cell phones, computers, or electrical cords.
Lead, on the other hand, was used in some electronic components, such as cathode ray tubes (CRTs) in old televisions and computer monitors. These products have largely been replaced by newer lead-free technologies.
Thus, the answer is lead.
