E. THERE WAS A SURPLUS OF LABOR BUT NO AVAILABLE JOBS

Who ever gives me the right answer will be given the brainiest

Answers

The correct answer is letter B

The Black Death was a pandemic, that is, the widespread proliferation of a disease caused by the bacillus Yersinia pestis, which occurred in the second half of the 14th century, in Europe. This plague was part of the series of events that contributed to the Crisis of the Lower Middle Ages, such as the peasant revolts, the Hundred Years War and the decline of medieval cavalry.

The Black Death has its origin in the Asian continent, precisely in China. Its arrival in Europe is related to the commercial caravans that came from Asia across the Mediterranean Sea and arrived in European coastal cities, such as Venice and Genoa. It is estimated that about a third of the European population has been decimated because of the plague.

The disease spread, initially, through rats and, mainly, fleas infected with the bacillus, which ended up being transmitted to people when they were bitten by fleas - in whose digestive system the plague bacteria multiplied. At a more advanced stage, the disease began to spread by air, through sneezing and droplets. The precarious conditions of hygiene and housing that medieval towns and villages contributed to the spread of the disease - which offered conditions for the infestation of rats and fleas.

Answers

Answer:

Explanation:

Final answer:

The overproduction of goods in the 1920s contributed to the Great Depression through underconsumption and the unequal distribution of wealth.

Explanation:

The overproduction of goods in the 1920s contributed to the Great Depression in several ways.

Firstly, U.S industry had grown significantly and was producing consumer goods at an unprecedented rate. However, consumers both at home and abroad were unable to purchase these goods due to financial hardships, resulting in underconsumption.

Secondly, the unequal distribution of wealth meant that the majority of American families had no savings, leaving them vulnerable to job losses and leading to homelessness and hunger.

Why was the battle of the bulge important

Answers

The Battle of the Bulge was the result of a last ditch effort by the Germans to turn the tide of battle back in their favor in the West. The German plan was to drive through the Ardennes and capture the port of Antwerp vital to the Allied war effort.
Final answer:

The Battle of the Bulge, a major World War II battle fought between 1944 and 1945, was significant due to it being the last major offensive from the Germans and the resulting depletion of German forces leading to their inability to resist the final push of the Allies. It also showcased the durability and resolve of the Allied forces.

Explanation:

The Battle of the Bulge, occurring during World War II, was important for several reasons. The battle got its name from the 'bulge' in American frontline on maps, caused by the surprise German offensive. It was fought late in the war, occurring in the winter months between 1944 and 1945. It signifies the last major offensive effort by the Germans to halt Allied forces on the Western Front.

Strategically, it was important for a couple reasons. One, it severely depleted the German forces, rendering them less capable of resisting the final Allied push into Germany. Two, it further united Allied forces, showcasing the durability and resolve of the American forces despite the surprised attack and initial setbacks. In essence, the Battle of the Bulge marked a definitive turning point in the war in favor of the Allies.

Andrew Carnegie gained control of a large percentage of the steel industry by doing all of
the following EXCEPT (1 point)
buying out his competitors
underselling his competitors
O cutting the quality of his products
buying out his suppliers

Answers

The correct answer is cutting the quality of his products

Andrew Carnegie was a Scottish businessman, responsible for founding Carnegie Mellon University, an educational institution located in Pittsburgh, in the United States.

Carnegie started working as a picker when he was a child. He became the richest man in the world.

Already on North American soil, he started working as a bobbin picker and thread spools in a cotton factory. At the company, Andrew Carnegie caught the eye of a coil manufacturer, who offered him a more advantageous job. Then he was a messenger for another company. His insight helped him to understand the city map and the faces of important people - and so he made several contacts. Little by little Andrew Carnegie grew in the company. In 1953, he left to work on a railroad. At 24, he was superintendent. At the post, he brought his younger brother and a cousin to work with him. In 1865, Andrew resigned to start his own company, the Carnegie Steel Company, which built Ohio's first steel bridge, and Union Iron Mills. Through the Carnegie Steel Company and applying the knowledge he acquired from Thomas Scott, his former boss, he invested in the steelmaking process. This dominated the metallurgical industry in the city of Pittsburgh.

Final answer:

Andrew Carnegie improved his hold on the steel industry by buying out competitors, underselling them, and purchasing his suppliers. He did not, however, compromise on the quality of his products.

Explanation:

Andrew Carnegie, a pivotal figure in the American steel industry, used a strategic approach to dominate his sector. He implemented various strategies such as buying out competitors, underselling his competitors, and even acquiring his suppliers. However, what he did not do to expand his reach within the steel industry, was cutting the quality of his products. This option does not align with the business growth measures undertaken by Carnegie.

Which is true of Adam Smith's “laissez faire” (hands off) capitalism?
Select one:
a. government should own major industries
b. the economy should be controlled by the ruler
c. all citizens should be equal
d. government should have a limited role in the economy

Answers

Answer: D) government should have a limited role in the economy

Explanation: The whole idea of laissez-faire economics is that the government should stay away (hands off!) from the economy. The first two are obviously eliminated, and the third one has nothing to do with economics, so that one is eliminated as well.

Final answer:

The true statement regarding Adam Smith's 'laissez faire' capitalism is that the government should have a limited role in the economy. This approach emphasizes minimal government intervention in markets, advocating for economic self-regulation and the invisible hand to guide efficient resource allocation.

Explanation:

The correct answer to the question “Which is true of Adam Smith's “laissez faire” (hands off) capitalism?” is d. government should have a limited role in the economy. According to Adam Smith, the “father of modern capitalism,” a laissez-faire economy means that the markets should function with minimal government intervention, allowing private markets to operate efficiently. Smith’s laissez-faire economics advocated for the principle that the invisible hand of the market, rather than government policy, should dictate production, pricing, and distribution of goods. Proponents of this theory believe that the government’s role should be limited to protect the freedom of the marketplace, which in turn promotes competition, drives innovation, and leads to a more efficient allocation of resources. The philosophy suggests that when the government refrains from heavy regulation or control, market forces are able to self-regulate, thus creating a cycle of economic growth and natural contraction which adjusts over time without the need for intervention.
