Answers

Answer 1

Explanation:

. The forced-draught (bellows-operated) shaft furnace known from archaeological studies is usually regarded as the pinnacle of this early smelting technology1-3. Examples of natural-draught furnaces, in which gas buoyancy in a shaft of sufficient height induces a draught adequate to drive the smelting process4, are also known, but are generally regarded as disappointingly inefficient by comparison5. Here I report the discovery and excavation at Samanalawewa, Sri Lanka, of a previously unknown furnace type. The furnaces are all situated on the western margins of hills and ridges, where they are exposed to the strong monsoon winds. Field trials using replica furnaces confirm that this furnace type uses a wind-based air-supply principle that is distinct from either forced or natural draught, and show also that it is capable of producing high-carbon steel. This technology sustained a major industry in this area during the first millennium AD, and

Answers

what is the significance of classifying people in Germany as " without citizenship rights "​

Human rights constitute a concept that is similarly predicated on different

forms of life.52 In other words, the concept of “human rights” intervenes in different activities

human beings, which endow it with meaning. Which does not mean that it has to be put to use.

Indeed, among the main forms of life in which the concept "rights

the dignity of the person, the different “ways of life” where they participate should be considered

human rights. Human praxis in favor of these rights requires reflection

philosophical that accounts for human rights and allows their better understanding; of the

political and pedagogical actions that are carried out in the social sphere; and the instruments

It will be the object of the second chapter of this research to deepen on an understanding

a. What were the two technological inventions during the Industrial Revolution and how did they affect the tourism and hospitality industry?

Answers

Answer:

Steam engine (two inventions/examples)

Explanation:

The steam engine helped tourism because it allowed people to transport from place to place with greater speed, which opened up opportunities for travel. Increased opportunity, or demand, for travel, means increased opportunity/demand for tourism; small towns will be wondering what could attract more people to their area because a higher population means generating a greater profit for the town. One example of the use of a steam engine is Steamboats. This allowed people to travel over water quickly and in great numbers, helping introduce tourists to different sights or interests along the shoreline.  Additionally, there is the invention of railroads and steam-powered trains. Trains could travel wherever tracks could be built, which opened up opportunities for travel and tourism in several mountain towns, such as Georgetown, CO.

On November 9, 1989, demand for change built up in East Germany which resulted in demonstrations in many East Germany cities. Growth in democracy in Hungary meant that East Germans could travel to West Germany via Hungary and Czechoslovakia. As soon as democratic elections were announced in Hungary there was a mass movement of East German citizens through Hungary to West Germany. As a result, the East German government was forced to announce much greater freedom of travel for East German citizens. As part of this decision, the East German government announced that East Germans would be allowed to cross the border with West Berlin. This led to German reunification and East Germany ceased to exist. It also began the "thaw" to the Cold War.

Select the correct answer. Which is the best example of a primary source document useful in the study of history? A. a documentary with expert analysis of the event in question B. a peer-reviewed article written about the event by a respected historian C. a professorial analysis of key battlefield strategies of the event D. a journal excerpt from a person involved in the event in question

Answers

Answer:

D. a journal excerpt from a person involved in the event in question

Explanation:

The person involved in the event would be the best person to know what happened in the event because they were there and could experience exactly what was happening. A documentary, article, and analysis would not be primary source because the people who wrote them were not there at the event.

Answer:

Primary sources typically originate directly from the event, people who took part in the event, an observer who is witnessing the event, or written thereby shortly after the event.

D. A journal excerpt from a person involved in the event in question

In the answer choice of D, it states that 1) The Journal is by a person involved in the event. This is the indication of the person directly participating in the event, thereby making it a primary source.

However, note that just because it is a primary source, does not mean it is the most accurate. Primary sources are heavily influenced by the person's beliefs as well as their perspective, and should not be used as the only basis for conclusion.

Based on these documents, what socioeconomic and sociopolitical conditions in late medieval Europe do you think combined to ‘‘infantilize’’ women and severely limit their legal rights?

Answers

According to the reading of the documents, we can see that the lack of education and the limitation to social and economic experiences were the elements that helped women to be "infantilized" in Europe at the end of the Middle Ages.

As we can see in the documents presented, women were not allowed to participate in courts, to sell and buy goods, to own goods, to sign contracts, or even to receive adequate education. These women were seen as totally dependent on their husbands and incapable of doing anything.

This lack of education and lack of experience with the social and economic sectors of society contributed to women not finding out how to act alone and encouraging concepts that devalued them.

This allowed:

Women were devalued.Women were negatively exploited.Politicians use women's inability to limit rights related to them.Women lived with severe limitations for many years.
