What was the outcome of the Battle of Kettle Creek?
A. The colonists were victorious and Patriot morale improved.
B. The colonists were defeated and Britain recaptured Georgia.
C. The colonists were defeated and Georgia declared its loyalty to England.
D. The colonists were victorious and the last British forces left Georgia.

Answers

Answer: The answer is D

Explanation:

I believe the answer is A. Explanation: A militia force of Patriots decisively defeated and scattered a Loyalist militia force that was on its way to British-controlled Augusta. The victory demonstrated the inability of British forces to hold the interior of the state, or to protect even sizable numbers of Loyalist recruits outside their immediate area. (Note that the Loyalist militia were American colonists who stayed loyal to the British Crown during the American Revolutionary War. The Loyalists were opposed by the Patriots, who supported the revolution.)

US Navy Rear Admiral asked naval historians to investigate the Maine’s sinking.
Answer: Rickover

Answers

The correct answer to this open question is the following.

The US Navy Rear Admiral who asked naval historians to investigate Maine’s sinking was Admiral Rickover.

In 1898, during the actions of the Cuban independence movement, a big war American ship was anchored on the harbor of Havana City, the capital of the Island of Cuba. On February 15, 1898, the Maine ship was attacked -some say it was a mine- and destroyed the ship, killing 260 people. The United States reacted swiftly and this incident represented the beginning of the Spanish-American War of 1898.

Let's end this comment by adding that nobody has been able to satisfactorily explain what really caused the sinking of the Maine ship.

Rickover, dressed in full Hyman garb George Rickover, and American naval officer and engineer, was born in Markov, Russia, on January 27, 1900, and died in Arlington on 1986.

Admiral Rickover

Admiral Rickover rose to prominence as the man who oversaw the building of the first naval reactors. Many believed Spain was responsible for the primary sinking at the start of the investigation. Spain was absolved of suspicion during Rickover's investigation, and it was determined that spontaneous combustion in the ship's coal bins was the primary cause of the explosion.

What are the characteristics of a civilization and why can that turn be problematic

Answers

The correct answer to this open question is the following.

Although there are no options attached to further context or reference, we can say the following.

The characteristics of civilization are they have cities, a form of government, the presence of religions, solid culture and art, defined social structures, record keeping of time and events, education, and the presence of certain kinds of technology that allows the civilization to prosper.

The turn of civilizations can be problematic in that the evolution of man and its social structures is not an easy task to accomplish because humans have different interests regarding politics, and power.

Unlike most countries in the world what do the citizens of the US not share?

A. Desire for freedom

B. common ancestry

C. Responsible for government

D. Aspiration for our young

Answers

B. common ancestry because immigrants have in the past (think Ellis Island) and still do come from many different countries to live in the U.S.

Common ancestry do the citizens of the US not share unlike most countries in the world. Hence, option B is correct.

What is Common ancestry?

The connection between two people who are related by blood. An ancestor that two or more descendent lineages share, or an ancestral organism that they both share, will cause the children of two parents to be inbred.

Instances of common ancestors include the parents and grandparents of two biological siblings; the first canine and the first mammal, respectively, are examples of common ancestors for coyotes and wolves.

Despite the fact that common ancestry—the idea that all currently existing organisms on Earth and all modern fossils can be traced back to one or a small number of "original progenitors"—is a key element of the Darwinian picture, most commentators agree that Darwin's theory is more commonly known as the theory of evolution by natural selection.

Thus, option B is correct.

What phrase from paragraph 3 is an example of something that is being described as “perennial “ ?

Answers

This question is incomplete. Here's the complete question.

"Nature is a setting that fits equally well a comic or a mourning piece. In good health, the air is a cordial of incredible virtue.

Crossing a bare common, in snow puddles, at twilight, under a clouded sky, without having in my thoughts any occurrence of special good fortune, I have enjoyed a perfect exhilaration. I am glad to the brink of fear.

In the woods too, a man casts off his years, as the snake his slough, and at what period soever of life, is always a child. In the woods, is perpetual youth. Within these plantations of God, a decorum and sanctity reign, a perennial festival is dressed, and the guest sees not how he should tire of them in a thousand years. In the woods, we return to reason and faith.."

-From "Nature" by Ralph Waldo Emerson; 1836

What phrase from paragraph 3 is an example of something that is being described as "perennial"?

Answer: perpetual youth

Explanation:

In this context, the word 'perennial', used to describe the festival that is nature, means that something is continuing, permanent.

Youth is described as perpetual, a synonym of perennial, to explain that in nature, humans, and animals, such as a snake, become young forever, 'always a child,' meaning that they are pleased in that environment and can never get tired of it.

What imperial nations had colonies in Africa in 1900?

Great Britain, France, and Germany

Answers

Answer:

D: Great Britain, France, and Germany

Explanation:

In 1900, Germany, France, and Great Britain all had colonies in Africa. As a result, choice (D) is the best one.

What is a colony?

A colony is a territory that is currently administered by another nation. The term "colony" comes from the term "colonia," which refers to a particular type of Roman settlement.

Since the early modern period, historians, executives, and political theorists have frequently used the term "colony" to refer to the different foreign possessions of nations, mainly those of Europeans, between the 15th and 20th centuries CE, with colonization and decolonization as associated occurrences.

Despite the fact that commercial outposts and territorial claims frequently served as the impetus for colonization, these areas are not invariably the site of colonization or the development of colonially structured territories.

Some historians refer to a country that is de facto ruled by another state by using this phrase, though it is commonly disputed.

Hence, Option (D) is correct.

Cattle drives were long and difficult: cowboys spent months on the trail, helping cattle to reach their destination while looking out for many obstacles. Why were cowboys and ranchers eager to meet these challenges? What motivated them to use trails to drive herds north from Texas to Kansas? Explain your answer in a paragraph of no fewer than five sentences.

Answers

Answer:

Responses may vary but should include some or all of the following motivation: The biggest factor motivating ranchers and cowboys was a chance to make a profit on selling their herds. Following the Civil War, Texas experienced a large surplus of cattle. This meant that prices were very low. However, ranchers realized that they could sell their cattle for much higher prices in railroad cities, where high demand would send these cattle to Eastern and Midwestern states. Cattle drives led thousands of livestock north to railroad towns, and ranchers made huge profits on these herds.

using slaves in Europe to manufacture good to sell to colonists.

banning colonists from fishing or trading in animal furs.

having to pay high duties on foreign sugar and molasses.

Answers

Answer:

Having to pay high duties on foreign sugar and molasses.

Explanation:

During the colonial era, especially from the mid-1700s, Britain began to carry out increasingly protectionist policies regarding its production, framed in the mercantilist concept of economic production. Mercantilism, in short, established that the wealth of a country is mediated in terms of its production of resources and its territorial extension, which allowed nations to accumulate wealth.

In this context, the British government began to prohibit its colonies from trading with other European nations (as this would benefit their economies), establishing commercial monopolies in the colonies, which implied a huge loss of rights on the part of the colonists, harming their economic and political freedoms.

Answer:

Jefferson believed that this rights are the right  to life, liberty, and the pursuit of happiness. Centuries later they are the foundation of American society. On the other side I don't believe that Jefferson believed in equality as he was holding slaves himself, thus showing that he don't believe in that idea truly.

Explanation:

Jefferson was obviously really affected by Locke's idea, as he incorporated many of those ideas in the Declaration of Independence. Actually, right to life and liberty are ideas proclaimed by Locke, while Jefferson added a part about pursuit of happiness. We can't say that Jefferson really believed in the equality of all people, as he owned plantation in which hundreds of slaves worked.
