What is a landmark case?

The correct answer is: "everything has a cost, if not a explicit one at least a opportunity cost".

The opportunity cost has to be considered when making a decision. It is defined as the value of the best alternative rejected when choosing a certain option. This concept shows that every good/service, even when it is consumed at a zero price, entails a cost. For example, there is a free concert in the street, but the time spent on its consumption is a resource that could be dedicated to an alternative activity that has a value and such value is the opportunity cost.

The phrase 'There is no such thing as a free lunch' pertains to opportunity cost, implying that every decision involves a trade-off because using resources one way means giving up the opportunity to use them in another way.

The phrase 'There is no such thing as a free lunch' illustrates the concept of opportunity cost. Opportunity cost refers to the potential benefit that one misses out on when choosing one alternative over another. If one spends their time or resources on one thing, they are sacrificing the ability to spend it on something else. In other words, every decision comes with a cost - even if it's not immediately apparent. Hence, regardless of the choice made, something has been given up - there's no 'free lunch'.

Answer:

The idea of total war existed in all countries involved in World War I. For example, countries used rationing to determine how much food, rubber, gasoline, and other items each citizen could use during the war. In order to draft more soldiers into the military, many of the nations established a policy of mandatory conscription. Some countries also controlled public opinion during the war by using censorship to prevent discouraging news from reaching the public.

Explanation:

The correct answer is (A): The creation of the Children's Bureau, a federal agency.

Progressive reformers such as Jane Addams were instrumental in advocating for social reforms in the late 19th and early 20th centuries. Jane Addams, in particular, is known for her work in settlement houses, which provided support and services to the urban poor. One of her significant achievements was her involvement in the establishment of the Children's Bureau in 1912. The Children's Bureau was the first federal agency in the United States focused solely on improving the lives of children and their families.

Let's examine the other options to understand why they are not the correct answers:

B: The building of more tenement houses in New York City - Progressive reformers actually fought against the spread of tenement housing due to its association with poor living conditions. They advocated for housing reforms to improve living conditions, not for the construction of more tenements.

C: The creation of a 10-hour work day for children - While progressive reformers did advocate for labour reforms, including limiting the work hours for children, the specific achievement of a 10-hour workday for children was not a standalone accomplishment attributed to reformers like Jane Addams. They pushed for broader child labor laws that aimed to regulate and reduce child labor.

D: The building of public transportation in Chicago - While improved public transportation was a concern for progressive reformers as part of their efforts to improve urban living conditions, the building of public transportation in Chicago was a broader civic improvement effort that involved many stakeholders, including city planners and business interests, and was not specifically an achievement of progressive reformers like Jane Addams.

Therefore, the most accurate answer that reflects an achievement of progressive reformers such as Jane Addams is A: The creation of the Children's Bureau, a federal agency. This agency was a direct result of the efforts of Addams and other reformers to address issues of child welfare and advocate for policies that would protect children's rights and well-being.

Explanation:

In his 2005 speech, Larry Summers suggested innate differences might explain why fewer women succeed in science and engineering. Historical and current examples like the Harvard Computers and the gender gap in STEM fields due to stereotypes support this suggestion.

In his controversial 2005 speech, Harvard President Larry Summers suggested that innate differences between men and women might be one reason why fewer women succeed in science and engineering fields. This suggestion provoked much criticism. His remarks can be understood within a broader historical and social context.

For example, the case of Harvard Computers in the late 1800s illustrates how educated women were undervalued in scientific professions. They were hired for one-fourth the salary of men and endured conditions that men would not tolerate.

Another example can be seen today in the STEM field where gender stereotyping persists, causing a significant gap between men and women. This stereotype presents men as the keepers of technological knowledge while women are subordinated.

Further, examples like that of Anita Hill show that women who venture into professions dominated by men often experience forms of harassment, causing further discouragement.

England and France established early colonies in North America, with England along the east coast and France primarily in Canada. Both engaged in trade and sought to expand their territories, influenced by economic prospects and land needs. Correct option is c).

England and France established early colonies in North America. This region was dominated by English settlements along the east coast and French settlements primarily in what is now Canada. Both nations sought to expand their territories and tap into the lucrative fur trade, among other resources. Whereas England started with permanent settlements such as Jamestown in 1607 and Plymouth in 1620, France claimed Canadian territories such as Quebec, founded by Samuel de Champlain in the seventeenth century.

The English colonies developed into a mix of agricultural plantations and trading posts, especially along the Atlantic coast. Over time, English colonization was influenced by various factors, including the economic drive for new markets and the need for land for England's growing population. Similarly, the French focused on trading, particularly in furs, creating relationships with native peoples, that helped them in their economic ventures in North America.

The direction that an ancient Mesopotamia travel to get Nineveh from Nuzi is "North."

If we see the map of ancient Mesopotamia, we can see the many powerful city-states it had across the Sumerian territory that was first established between the Tigris and Euphrates Rivers and spread from there to other regions. We can see in the map the important city.states of Nippur, Kish, Lagash, Ur, Uruk, Eridu, and Larsa.

The correct answer is B) trading cities became more important.

The effect that the Crusades had on trade was that trading cities became more important.

Trade was key during the Crusades. People needed products to be supplied in different war fronts and many cities became important centers of trade. Crusades found new products in the Middle East that later were brought to West Europe and people started to demand them. Muslim people also traded carpets, compasses, and different kind of textiles that when were known in Europe, were totally accepted and trade increased more.

Changes in the power and influence of the U.S. president have been driven by the nation's expansion, major crises, media, and international prominence. Early presidents expanded war powers, while the twentieth century saw presidents' power shaped by Congress, media, and a nation's readiness for change. Civil service reform and rising partisanship also played significant roles.

Several events have contributed to changes in the power and influence of the president of the United States over time. The expansion of the United States and the federal government's power, crises such as the Great Depression and wars, and the advent of electronic mass media have all played significant roles in the growth of presidential power. Notably, early presidents, such as Washington, Adams, and Jefferson, set precedents by engaging in undeclared wars, but it was President James K. Polk's actions during the Mexican-American War that notably expanded presidential war powers. In the twentieth century, circumstances like a supportive Congress, media attention generated by presidential popularity, and a nation's readiness to accept change shaped a president's ability to exercise authority.

Historically, weak presidencies during the Gilded Age, constrained by close elections and a Congress influenced by political patronage, led to limited presidential action. Civil service reforms reducing the influence of patronage, rising partisanship, and internationally significant events further influenced the balance of power, as did the invention and later evolution of the presidency since the Constitutional Convention of 1787. The nature of a president's election, their political circumstances, and the context of their tenure (“political time”) have also crucially impacted their ability to affect change.

Final answer:

The power and influence of the president have changed over time due to various events and factors, including the nation's growth, major events and crises, and the expansion of presidential war powers.

Explanation:

The power and influence of the president have changed over time due to various events and factors. As the United States grew and developed, the complexity of domestic issues and the nation's role on the international stage increased.

This led to people relying more on the president and the federal government for solutions. Additionally, major events and crises such as the Great Depression and the war on terrorism contributed to the increase in presidential stature.

Moreover, the expansion of presidential war powers, the growth of the federal government, and the rise of electronic mass media have also played a role in strengthening the power and influence of the president.
