Which resources most directly lead to the development of early civilisations in river valleys

Answers

Answer:

Not only do the river valleys provide food resources such as fishing, they also often have a wide, fertile floodplain readily suited for agriculture.

Explanation:

Even the earliest, least advanced farming technology would have been successful in producing a substantial crop surplus from a river valley's naturally fertile soil. Agricultural innovations that had been developed elsewhere were introduced into the valleys of the river and developed on a larger scale. In Mesopotamia,  Nile Valley, the Indus Valley, vegetation, and livestock thrived in the great river valleys in a quite significant form, especially after irrigation technologies were established to maximize the use of the region around the river.

O C. Serve on a jury at least once.
O D. Take an oath of loyalty to the United States.

Answers

The correct answer is D. Take an oath of loyalty to the United States.

According to this, option D is correct.

"Tough Guys 2," the traditional way of looking at violence as something that is_________, should be augmented with a new view that emphasizes that violence is something _________..

Answers

The correct answers to this open question are the following.

Although there are no options attached and no link to the video, we can say the following.

"Tough Guys 2," the traditional way of looking at violence as something that is instinctual, should be augmented with a new view that emphasizes that violence is something acquired.

Every human being has a duality that allows it to perform good deeds and bad actions. On the negative side, every human is violent. Some humans are more violent, depending on the situation. It is just a matter to push the "right" buttons so people could react violently. This aggression is part of humans, but it can also be an acquired behavior if the proper conditions are present. For instance, a youngster that hangs out with gangs or aggressive people. Or children that watch too many TV series full of violence, drama, and aggression.

1)Predict: How will supply and demand and labor substitutes in these job markets affect their pay and likeliness to get a job?

2)How will supply and demand within the job market affect my career choice?

Answers

Answer:

1)Predict: How will supply and demand and labor substitutes in these job markets affect their pay and likeliness to get a job?

Supply, demand and labor substitutes are three variables that will determine the wage.

For the medical field, the demand for doctors tends to be higher than the supply of doctors, because becoming a doctor is costly both in time and money. This means that doctors will be well-paid, according to this model.

Besides, there are not so many labor substitutes for a doctor, increasing the probability of a high pay for them.

The opposite occurs for barbers. Barbers are easier to supply, and demand is not as high for them. This means that a barber salary will be much lower than a doctor's salary. Finally, barbers do have more labor substitutes as well.

2)How will supply and demand within the job market affect my career choice?

Supply and demand within the job market, as explained above, largely determines the quality of the career that you choose. A labor market with high supply and low demand means that the chosen career will be paid less, while a labor market with low supply and high demand means that the chosen career will be paid high salaries.

What is one main reason some governments in the twentieth century began campaigns of genocide?

Answers

Answer:

One thing all governments have in common, is the act of attaining and upholding their ability to wield power, however they may do so. Governments in the 20th century typically rewarded supporters while rooting out any opponents, making them "disappear". The campaigns of genocide was to eliminate as much, if not all, opposition against the government, while rewarding supporters. Anybody on the fence on whether to support or resist, would see the results, and as a result, would themselves accept or support the government, whether whole-heartedly or reluctantly.

With power, a group can attain control, and with control, power.
