Powers and duties of the United States government are divided among two branches of government. C. Powers and duties of the United States government are chosen entirely by the President of the United States. D. Powers and duties of the United States government are decided by a system of direct democracy.

Answers

Answer:

The correct answer would be option A, Powers and duties of the United States Government are divided among the three branches of government.

Explanation:

Separation of powers means that the duties of government are divided among different parts of the Government. The purpose of this system is to make sure that power is not held by the central government only and is properly distributed among all the branches to serve all aspects of the society.

In the US system, there are three branches of federal government between which the power exists. The Executive Branch is the president and their staff including the Cabinet. The Legislative Branch is the two houses of Congress: the House of Representatives and the Senate. The third branch is the Court with the Supreme Court at the head and district level courts throughout the country.

Each branch has separate roles and each branch can check the power of other one.

What caused the decline of the Spanish Empire?​

Answers

Explanation:

The decline of the Spanish empire was brought about by many factors. Money was tight for the Spanish during the 17th century, despite that galleons filled with gold were sent from the Americas (though many were raided by pirates or were wrecked in storms). But conquering and forming an empire is one thing; maintaining it quite another. Often the natives of a conquered land are not happy with the conditions they're subjected to by the conquerors, just as often those conditions are brutal and unfair. So they rise up in arms, and that means that empire has to spend a lot of money on armies and weapons to extinguish it.

This is more or less what happened when the Dutch revolt, which finished during the 17th century. The Spanish colonies in the Netherlands rose because their Spanish rulers were not really interested in their needs and didn't solve any of their problems. Besides Calvinism was starting to spread like fire on hay and the Spanish were not only Catholic, but liked everybody in their territories to be Catholic as well.

Dutch revolt

The Dutch didn't exactly get their independence right away, but the way was paved. After the revolt a 12 year truce ensued, but as soon as Spain felt ready it attacked again, without much success. But war, beside expensive, is unpredictable. Who knows what might have happened if the French hadn't got involved? France and Spain had a strong mutual hatred and the French would befriend any of Spain's enemies. It became more of a war between France and Spain. Spain lost the war and territories and the right to be called a world power, bringing about the decline of the Spanish empire which the Anglo Spanish war helped cement.

On the home front things weren't going so great either. There were several revolts, including the Catalan revolt and the the Basque revolt among others, when the Count Duke of Olivares proposed raising taxes. For whatever reason the King relied completely a man with a record for causing trouble (his decisions had lead to the war with the Dutch and later France).

The last stroke would come from their neighbours. For some time now, Spain and Portugal had been joined in the Iberian Union, under Spanish rule. However when the Portuguese nobility began to lose their influence and power, when the Cortes and Portuguese posts were being occupied by the high Spanish classes, and when the taxes were raised by the Count Duke of Olivares, the Portuguese had had enough. How did they show their displeasure? By crowning their own king and expelling the Spanish from their country. They also befriended one of Spain's biggest enemies, England. In the end Spain was forced to recognize the Portuguese independence.

C. Belita sends a letter to her grandmother asking how to paint a picture.

D. Gary leaves a voicemail for his brother to remind him where to meet after school.

Answers

Answer:

B

Explanation:

It is B I think Because documentary movies are usually long and take a while. (I said I think so it may not be the right answer but it should be)

Option B is the case where mass media is used, as Eliji is watching a documentary film - a medium intended for the public. The concept of mass media encompasses a range of platforms like TV and newspapers, serving entertainment, education, and information purposes. The correct answer is option B. Eliji sees a documentary movie about historical sites in California.

In the provided case, mass media is being used in option B, where Eliji sees a documentary movie about historical sites in California. Mass media refers to various platforms used to communicate with a large audience, including television broadcasts, radio programs, newspapers, and the internet. In this example, the documentary movie is a form of mass media, as it is likely being broadcasted to a large public audience, possibly through TV channels or online streaming services.

To further explore the role of mass media, one could examine two different types of mass communication. For instance, television broadcasts often serve as a source of entertainment as well as a channel for news and educational content. On the other hand, a newspaper could provide in-depth analysis, local updates, and advertising apart from just the headlines. Understanding the multiple roles filled by mass media helps us recognize its impact on our daily lives and society at large.

Answers

Answer:

The growth in trade with Canada B. The completion of the Erie Canal C. The growth of the automobile industry

The correct answer is C) the growth of the automobile industry.

The occurrence that most likely explains why Detroit appears on the list of most populous U.S cities in 1950 is "the growth of the automobile industry."

In that time, Detroit was the 5th most populous city in the United States, just behind New York, Chicago, Philadelphia, and Los Angeles. It was known as the "Motor City" due to the many automobile manufacturing plants that were located in Detroit. These factories opened new jobs and living opportunities and many people decided to move to this place. Indeed, the headquarters of great automobile companies are in Detroit, such as General Motors, Chrysler, and Ford Motor Company.

The other options of the question were A) the growth in trade with Canada. B) the completion of the Eire Canal. D) the end of the severe drought in the Midwest.
